Wide vs Narrow Winter Tires Tested - What's REALLY Better on Snow and Ice?

[@tramvaj12]

It is a thread difference, smaller tires have the benefit of going through deeper snow ( much less power is needed ) You might have frosty snow ( it is painful to break icy patch with wider tires)

[@GMT439]

Rally Cars use narrower studded tyres for snow conditions. It's already a proven design.

Does tire pressure make a difference?

[@tramvaj12]

@@apocalypse487 depends of Snow condition. If it is powder. Doesn't matter. If it is packed or iced or in un even surfaces. Can help you get going ( the length of tire is matters not width) the more length you have the more acct as track.

I'm really disagree with your statement about the size of winter tyres! Coming from a country were we have 4 season's, mildly hot summer's and winter that lasts at least 4 months and were winter tyres are obligated by law in winter months. Winter tyres should always be two sizes narrower then summer tyres (225 in summer/205 in winter) the reason is simple, half of the time you won't get just ice or nice pressed snow surface as in your test track. Half of the time there will be melting snow slush, mixed salt/gravel and snow slush, fresh snowing snow and good luck getting any kind of grip in a 245 wide tyre, doesn't matter what brand it is,it will just float. Winter tyres are about safety on the road.

[@noahnovotny2100]

In my experience, in northern Minnesota people are much less concerned about turning and braking quickly than they are about getting stuck. I really wish you would do deep snow testing as a result. I’m sure it is difficult to find spots to get a consistent surface with 6-12 inch snow, but that is what matters to most people who have to go to work before the side roads and driveways get plowed. That is where the narrow tire would show the greatest advantage as well. I still appreciate all the in depth reviews! The best tire reviews on the planet currently.

[@ronboe6325]

Growing up in eastern Montana where snow plowing was iffy and rare tall narrow blocky snow tires were the bomb. Especially on ranch pickups. Deep to "deep" snow on paths and "roads" with no packed snow was the norm. Moving to northern Minnesota plowing was more reliable but we still had the problem with getting around in virgin snow before the plows hit (along with the problem of steep hills). Rear drive, rear engined or front wheel drive and front engined cars had real advantages. Again, tall narrow tires were preferred as the conventional wisdom that the tire wouldn't float but dig down to the road surface where the traction was. This test didn't answer that question; however, the packed snow conditions probably covered the conditions most folks will find today. But if this test could be replicated in deep virgin snow it would test the extreme boundary conditions. And who doesn't like testing snow tires?! :D

[@G5Hohn]

Grew up in WI and ND and second this stongly. Braking performance is a luxury of those who aren't stuck and are actually moving. For many of us, we can coast to a stop on rolling/plowing resistance alone in 6" of overnight snow.

The advantages of a narrow tire show up more in "slush planing" and pushing through deeper snow.

Which helps with acceleration, but during braking actually it helps to displace more snow with the wider tires.

[@gad63511]

This test was performed in a very cold place where the snow is basically ice-gravel. My intuition is that you'd see more differences between the widths if you tested on fresher, wetter, deeper snow. For me, my main motivation for winter tires is to not get stuck in fresh snow, especially when climbing hills. I'm not all that concerned about braking and handling differences because where I live, any time there's snow on the ground you're driving slowly anyway.

Absolutely. My city in Canada is avg. 0 to -10c in winter, lots of slush and fresh snow days. See lots of cars getting stuck on our steep hills and trucks with wide tires crawling on the highway as they're slushing all over the road. My van with 205/85 will go anywhere, no problem.. and they're not even snow tires, just All-Season AT. My buddy spun his 4runner into the ditch on 265/70 on packed highway and fully admits it was the tires; he went and bought narrow winters after that.

[@davesax11]

@@tyrereviews Snow is most slippery near the freezing point - that's the better temperature area to target.

[@bobs12andahalf2]

I live in a similar climate and can confirm that there is a sweet spot for tyre width that depends on the car (weight and its distribution is a factor) and the surface type. We mostly use studded tyres although studless are gaining popularity especially among people who mostly drive on heavily salted city roads. Studs are essential out of town where there is often sheet ice under snow. On the whole a narrower high-profile tyre is better all round with more grip, but the higher breakaway point means that when it starts to slide you're probably in big trouble. A wider tyre tends to slip more predictably and you quickly learn to keep within its limits.

[@jeffer1101]

I've always got the smallest option as that's what I figured made the most sense. From the looks of it, the difference is negligible, but the smaller tire options are often less expensive too. I guess you could look at this way; save some money and buy the smallest option, but use some of that savings to ensure you put it towards a quality tire. That way, you are getting the best of both worlds.

[@dthompson3426]

Yes. Assuming, of course, that you have rims to mount them on. If not, it will equate to roughly the same or slightly more to downsize.

[@mdocod]

You shouldn't be buying the smallest option, you should be buying the tallest skinny tire on the smallest rim possible. This gives you the option to run lower air pressure and produce a longer and larger contact patch than OE. What's your OE tire/wheel size, what winter rim size do you run? I'll provide an example...

[@leiflillandt1488]

If safety is important, it's difficult to choose something else than the test winner. If the same brand wins the tests year after year, how difficult is it then to choose a "good" tire?

[@jeffer1101]

@@mdocod yes, by "smallest", that's what I meant. I no longer run winter tires due to the hassle and cost. I put a set of Michelin Cross Climate 2 tires on my Venza and they've been excellent. Not far off from a good winter tire.

[@crisnmaryfam7344]

Take a second and google winter race cars, or winter rally drivers cars, take a look at ALL of their wheels. One thing remains the same among all of them. Narrow Tires. Studded or not, depending where its legal (in the ARA / Rally America Studded tires are not legal) they are always narrow. These guys drive at the limit, in multiple million dollar cars with million dollar race teams. If there was some performance to be gained with a wider tire on the snowy tracks/courses, Dont you think they would have done it?

[@Pesmog]

There are more potholes in the winter, so I always go for a smaller winter wheel rim with a taller side-walled tyre so that rim damage is less likely and for more comfort on rougher winter roads. I never deviate from the manufacturers list of approved wheel and tyre combo's for that vehicle though, I just move between the recommended sizes depending upon the season.

[@Wasabi9111]

Totally agree. I always try to get the smallest wheel diameter / largest tire sidewall as possible as our roads are horrible. Pot holes don’t get fixed for months - well into the warmer months.

[@phild9813]

Yeah I’m with you, even in summer. On a 20” wheel, you have to go to at least a 33” tire to have enough sidewall for comfort and protection. Of course I’m talking SUVs and trucks.

[@boboutelama5748]

Swiss guy responding there. We always try, when possible, to opt for smaller winter wheels. This allows more sidewall and is beneficial to find this little bit of traction. Also, never over-inflate winter tires, always opt for lower recommended pressures, as it will allow the tire to flex.

[@mdocod]

@@boboutelama5748 Very often a taller profile tire on a smaller rim will also have higher load ratings, allowing the winter tire/wheel setup to carry the vehicle with lower pressures safely, which produces an even longer contact patch, which makes the whole driving experience even more predictable, and more capable in deep snow.

[@ivonakis]

High side wall gives you piece of mind - curbs you don't see and the comfort. Additionally if you have 2 sets of wheel you can opt for better/more expensive tyres (my BMW needs every bit of help)

[@4u2nvinmtl]

Try testing in deeper snow, so you can see how they would handle on an unplowed road, that's where the narrower tire will cut through the snow VS the wider tire riding on top of the snow. This is when you will really notice the difference (usually during a snowstorm in an urban setting the snow turns to deep slick slush and the narrower tire find's much better traction than a wider tire).

[@jothain]

This. Compacted snow is quite rare imo in Finnish winter at least. It's like 80% of driving in "solid" surface like tarmac, ice or snow which is easy to control. But the the critical condition is the last 20% and that is like really deep snow and slush and these are the conditions where winter tyre performance is counted. Narrow tire indeed "sinks" better into hard base. Wide tyre can easily "hydroplane" on heavy snow or slush. My preference is high sidewall tyre to increase comfort and narrow to just easier to push through the surface as mentioned.

[@IV-A]

This is clear as day. Narrover is a game changer in slush and most of the time when there is slush there are cars in the ditch. I would like to see tire reviews test this. Also car Weight is probably a big factor. Wider tire on a 2000kg car is not as bad as 1400kg car.

[@jothain]

@@IV-A For sure. I had one light car that had really wide tyres for it's weight and it was downright scary in certain situations. It got much better with original tyres.

[@mdocod]

The narrow tall profile tire actually does exactly the opposite. It has a slightly narrower tread, combined with lower inflation pressures, produces a significantly longer patch (around square shape) that gradually packs, paves, and climbs over the snowpack formed by the leading edge. It is the low profile tire, with rigid reinforced sidewalls and higher inflation pressures and a very short contact patch that is incapable of engaging with the standing snow in a manner that packs and paves a path over it. The short contact patch of a low profile tire winds up "falling" through, digging its own grave, and getting stuck in a hole that it can't pack and climb its way out of.

[@jothain]

@@mdocod not that much, cause outer diameter doesn't change that much in tires anyway, except for extreme cases. Low profile = bigger rim. High profile = smaller rim. End result doesn't change vastly on conventional tire sizes. But comfort does change. We're talking really small contact patch changes.

[@carcontrolschool]

Having done several years of Ice Racing in the CASC Ice Racing Championships combined with running our Winter Driving schools for over 20 years at our iced facility and having conducted numerous tire tests, we did notice that a narrower tire has advantages in deeper snow/slush conditions. What is important to note though is any winter tire will out perform any all season tire in winter conditions. Get yourself a good quality set of winter tires. ILR Car Control School

[@beyondEV]

The advantage / disadvantage actually depends on vehicle weight compared to tire size. Personal experience from winter service while driving stuff between 400-3000 kg (small plows to heavy cars). This is especially true for the deeper snow / slush part. Doing the Physics would agree, the additional pressure allows the dig into harder snow/slush deeper down.

[@maximilianmustermann5763]

All season tires are kind of stupid because they are very mediocre in summer and also very mediocre in winter. Now if you're like my 78 year old mom who basically just drives to the grocery store all year round and has the freedom to not drive when it snows or when conditions are bad - get all season tires and save some money. But for everyone else, don't do it.

[@carcontrolschool]

@@maximilianmustermann5763 We did tire testing for Goodyear and couple of years ago and we tested their All Weather tires (not All Season) and they performed better in all seasons than an All Season but still not as well as a Winter tire in winter conditions.

We liked it better than the all season in spring, summer and fall.

[@LikelyCandidate]

A narrower tire will feel less resistance when moving through thick slush or snow at speed. This could help prevent you from getting pulled in further off the road. Going one size narrower could also save you some money on a set of tires. In my recent case, the difference was about $100 on a set of 4 from a 225 to a 215.

I’d be interested in comparing tire pressure effect on traction, both dry and wet pavement AND snow and ice, to what vehicle manufacturers want vs what the tire manufactures want for static loaded radius. If a change that can be made for free affects performance I’m sure many would want to know.

[@lars_hbm]

The tire pressures are defined by regulations through the ETRTO (european tire and rim organisation). Multiple factors and formulas define the lowest pressure for the specific tire dimension, vehicle mass, maximum car velocity, camber angles etc. Going lower that this exact pressure might be performance enhancing but not street legal as the tire supplier does not guarantee a longterm durability anymore and therefore no insurance will cover you in case of an accident.

Super interesting test. Some things to consider : 1. A lot of cold areas will see a mix of conditions, sometimes snow, ice, slush, rain, wet and dry pavement. In some areas a driver can experience a combination of any of those in winter, in a single trip! 2. Though it’d be a lot of work to do all this additional testing on 4 different sets, it’d bring additional considerations for finding the best overall width for a well-rounded winter experience. 3. Without much doubt the wider tire would do better on dry and wet than narrower tires; maybe not so much in the rain (hydroplaning). 4. I’d be curious to see how studs would influence the results. Do wider tires have more studs overall? It probably varies from a model to the next depending on the design choices the manufacturers made. But if a particular model has more studs on the wider sizes, then that could very positively improve results on ice. Thank you for all the hard work 👌

[@meverkko]

I know it's hard to test, but I would have liked to see tests in loose snow and slush. Living in Finland I've opted for a narrower winter tyre for behaviour. With patches of ice/snow/slush between tarmac the transition from sliding a bit to not sliding is much smoother with a narrower and higher tyre. The narrower tyre might have a bit more traction in the slippery but more significantly it is not so sharp when you either loose grip or get it back.

[@corail53]

No one ever does these tests on real world applications of wet roads with slush and black ice in patches, throw in some rain as well. They either have dry snow (which grips awesome) on a track or straight up ice which just isn't the case for everywhere.

I knew a mechanic who’s family raced in an ice league in Vermont (on frozen lakes) and he told me that “surface pressure” only mattered for the deep spiked tires.

Just like driving in sand, under braking a certain amount of snow is pushed up in front of the tire. With a wider tire the amount of snow pushed up in front of the tire also increases, helping the car to slow down. Under acceleration there is no build up. Hence the narrow tire performs better due to the higher pressure delivering more bite and the wider tire have better break performance due to the broader heap in front of the tire

Great test Jonathan, well done for doing this one! I have always tended to fit narrower tyres, mainly to have a higher sidewall for general winter use and better performance in slush.

I have driven them extensively on snow-covered roads in Scotland and in the Alps. The other benefit of a narrower winter tyre, is actually better aquaplaning performance on rain-soaked motorways.

[@vehicle-stuff]

Yes, you did it again! Nice job. You are absolutely correct, for the regular road there is no difference in perfect conditions. But, when the roads are bad, when there are a lot of pot holes, and you can't see the curb then the bigger sidewall makes a difference.

[@louisolivierfortin]

One major thing to consider is that most days are not snowy nor icy suring the winter, at least where I live in Canada. So you end up driving on cold tarmac, which I imagine would favor a wider tire. I guess not going to the extremes is the way to go

Finally decided for broad tires on 19" for sake of style. But I was really worried that they might be much worse than smaller tires on 17". Thanks for this great test like always.

[@askmeaboutarcticcats]

That is interesting results. I would have imagined the narrower would have had a large margin of success compared to wider counterparts. As always good info!

[@Topsiekku]

In winter, it is always wise to choose a narrow tire. Today's cars have winter tires that are far too wide.

[@ranran2218]

I always thought the more narrow tire was significantly better for driving in snow. I've been educated now lol. Love these videos.

[@corail53]

Take this test with a grain of salt as its in very specific conditions that most places don't get. The real test should be on ashphalt - wet, slush mix, occassional black ice. That is the most normal and most dangerous type of conditions in winter almost everywhere. Dry snow is extremely grippy.

[@mdocod]

This test compares an UNDERSIZED skinny tire (smaller diameter), with no load index advantages to the low profile tires, so it has to be operated at the same pressure, which means it has the same contact patch size as the other tires, so not much advantage. A 205/65R16 or 215/60R16 at 30PSI would be the appropriate tire sizes (and pressures) for this test, not the 205/60R16 @ 35PSI.

[@nirfz]

Very thorough testing! (and not that surprising results except for a few tings). But what i think people should keep in mind is that if they aren't driving on snow there are other differences too: In the dry, the wider tyre will be better in traction and braking and cornering, and in the wet it most likely will too. But the narrower tyre will be better in hydroplaning and in slush. And here 20mm in width per tyre can make quite the difference. And lastely the narrower tyre will cost less. (sadly, something people often are more concerned than with performance, even though hitting something and the repair afterwards cost more than a set of premium tyres.) So someone could buy a good winter tyre in a smaller dimension for equal money as if buying a shitty tyre in a bigger dimension.

Big sidewalls are just great for comfort and better fuel economy

I used to be convinced narrower tires were a must for winter. But when I got my current car with 225/40/18 in the front and 255/35/18 in the back I decided to just get winters and stick with the same set of wheels until I find a good second pair. I got Michelin Pilot Alpin 4's and my subjective feeling was that width made no significant difference. Great to see it backed up with actual testing.

[@tyrereviews]

Glad we match :)

[@helldogbe4077]

Yeah, I used to love the extra comfort going down a size (in width and sidewall height) but it also meant more mushy turn in and less grip on dry and wet roads. Nowadays I stick to the same size so the handling changes much less (although I am on a sporty winter tire -michelin pilot alpin- and a much less sporty summer tire -michelin primacy 4-)

[@ninik35]

@@helldogbe4077 Pretty much the same for me. I also found I prefer to keep the sportier feeling vs the extra comfort of the thicker sidewall. And actually in a similar situation with my tire setup. I was on hankook s1 evo 3's for summers and pilot alpins for winters. Whilst the hankook is technically a more sporty tire than your primacy I can't really call it a UHP tire at least not on subjective feel. It has loads of grip but steering feel isnt great. So I also see little to no change from summers to winters. But I'm due for new summers next year and planning to try the f1 assymetrics

I just love how it came down to the conclusion I had after driving Hankook in winter and switching to Kleber.. I got my E46 320D Touring for 14 years now, drove Hankook 205/55r16 through several winters, but Kleber had a slightly cheaper option in 2019. Well as the Krisalp HP3 only works really well in under 0 Celsius it really shows its age after being 3 years old, and last winter (January 2024) in deep snow it was nearly undriveable.. Whereas Hankook I used throughout the 6-7 years of it's lifetime without any hiccups..

[@Garsuniy]

I went for a more narrow tire for winter because it gives me more sidewall and thus more comfort and relaxing driving, which improves safety in a non-obvious way. And yeah, no potholes or just holes are dangerous enough while driving pleasure I can get with far better summer.

[@douglaswatt1582]

We have been spoiled by Tyre Review's consistent excellence. Another very fine review!

[@JohannesDahl42]

Fascinating! My takeaway here is that, since tyre sizes vary in terms of popularity and price, it makes sense to shop around to get the best tyre you can afford in any size that fits your car. Example: My old BMW 1 series came with 205/50R17, but I'm on 205/55R16 (also within spec) in the winter (cheaper -- €140 vs €190 per one Michelin X-ice North 4) and either 215/45R17 or 225/45R17 (neither size recommended by BMW for the front axle) in the summer (better selection, including one or two UUHP options, none of which were available in my size last I checked; also wildly cheaper -- €97 vs €173 per one Goodyear Eagle F1 Asymmetric 6).

[@mdocod]

The 205 size they tested was under-size diameter wise and had no advantage in load index compared to the 255, so had to run the same pressures to hold the weight of the car safely. Had they tested a proper 215/60R16 or 205/65R16 aired down about 5PSI below the door sticker, the skinny tires would have run away with all of these tests AND provides the car far more real-world advantages in deep snow and slush, as the tires contact patch acts more like a track, able to climb the problem rather than dig out a perfect little grave for itself.

I've 'always" bought narrower winter tires. I learnt a bunch in this video. BUT more importantly I've always wanted a TALLER tire (the tallest I could fit on the car in winter) A 205/75/16 NOT a 205/50/16!!! ie I wanted the tallest tire so the car would be slightly lifted in the deeper snow that I travel in a bunch. ALSO taller than most other cars so now You are "not" the one pushing snow on already driven roads (before plow comes along - happens a lot) SOOOO Now I will buy the TALLEST tire I can fit & worry less about getting the narrowest tire.

Test in deep snow could tell much more about the width

[@vipercrazy-9]

Went from 205 to 195 on my mom's Corolla for the winter setup, the 195 is OE on the base trim below hers so I was able to buy factory steel wheels one size narrower. I had a 02 Legacy with 205/55/16 which was narrow for a OE size for how heavy those cars are, and it was incredible in snow with cheap all season tires. Keeping in mind car weight and tire width I feel is very important when considering snow traction.

[@furieux6742]

Agreed. Its soo much important. 185 its fine to 1200kg. 195 its fine to 1200-1350 205 1350-1500- 215 1550-1700- 225 1650-1800 about. I drive a bus 195 2.2tons and crazy how grip it is... better small tire than other

For my Porsche Cayenne S, I followed the OEM sizes of 285/40/22 Front and 315/25-22 Rear. I figured the ultimate ice and snow traction might be lower than going with a narrower setup, but the trade off would be better handling in the dry/wet where the car will spend the majority of it's time anyway. After seeing this review, it seems even the ice/snow handling won't be very different anyway, so I'm very happy with my choice now!

[@mdocod]

Ever been stuck on dry pavement? Are you driving around corners so fast in the dry on public roads that you need that much lateral grip in the dry? Anything you could do that would find the limit of traction on those tires on dry pavement would be a spend-the-night-in-jail sort of traffic offense. On the other hand, I see sport SUV's with low profile's stuck all the time in the heavy slushy stuff. They dig their own grave with no sidewall flex to climb out of compacted slush. A tiny bit of wheel spin and they are locked into these cute little perfect dishes in the compacted slush shaped just like the perfectly round tires/wheels with no flex. This test is actually very flawed, as it fails to take into account HOW to employ a skinny tire setup properly. By choosing an undersized skinny tire (Smaller diameter than the rest) they did not gain any load carrying capacity compared to the other tires, so they had to run the same pressure, so they did not get any additional contact patch. They should have run a 205/65R16 or 215/60R16, and dropped the tire pressure by 5PSI (same load carrying capacity here)... and then added a real world unplowed heavy snow test.

Yes less rolling resistance... But also less grip so more dangerous

[@nirfz]

Narrower tyres also have less aerodynamic resistance, less (unsprung) weight, are better at hydroplaning and in slush and cost less. They are a little"worse" in dry and wet performance though than the same tyre in a wider format.

[@rjeffm1]

I live in Ontario, Canada. Snow tires are there first to keep you from getting stuck. If conditions are bad enough that thats a concern, you have no business driving fast enough to be worried about turn in, etc. Braking is of course very important, but again in snow and ice, you need to be going slow, and braking gently and well in advance of your summer approach. One last point: if you attempt "spirited" driving on snow and ice on a regular basis, you will either wind up upside down in the ditch, or wrapped around a telephone pole.

[@peterscott2662]

Interesting. I think the theory about narrow tires is the largest benefit driving through deeper snow. The theory being that there will be less floatation with the narrow tire. Floatation when driving down a snow accumulated highway is bad news. The only time I ever left the road was driving through an unexpected snow storm driving to visit family for the holidays. Snow removal was not keeping up with accumulation, and soon the car was disconnected and floating, even driving 30 MPH on a 60 MPH highway... Though it is more difficult to test scenario, than a snow packed track. Also I can think of a benefit to snow braking with a wider tire, provided ABS doesn't interfere too much. You get the best snow braking from building up a wedge of snow in front of the tire. Wider tire = wider wedge... I'd probably do what I've always done, go to smaller steel wheels, with taller sidewall, and maybe one step reduction in width. This ends up being less expensive, than wider aspect tires anyway.

[@mdocod]

Actually a properly set up skinny tire provides more floatation than the wide tire when appropriately selected and aired... This may seem counterintuitive but this is desirable. In this test, they ran an UNDERSIZED skinny tire with the same load rating as the wide tire, so required the same air pressure to carry the load safely. No sane person would go with a smaller diameter tire for their winter tire. It's best to oversize on the diameter while stepping down on the width and wheel sizes to get the LONGEST tread patch possible. By stepping down to a smaller rim, and sizing up the diameter, we can get more load index, which generally buys about a 3-8PSI advantage in load carrying, allowing the tires to be operated at lower pressure and a larger contact patch. The tire size they SHOULD have run for this test, is a 205/65R16 or 215/60R16, which can both carry the BMW tested at 30PSI rather than the 35PSI on the door. A 255/35R19, has very poor floatation as its contact patch is very wide and short, so it "squeezes out" the snow/slush in front of the tire rather than climb the snow and gradually pack it down. A 205/65R16, operating at reduced air pressure for the same load, has fantastic floatation, as its contact patch is closer to a perfect square, and the weight transfers gradually as the tire climbs up on top and packs down a track that it can hold a grip on and continue to climb through. My OE tire size on car is a 235/40R18 XL @ 38PSI for full load and/or for high speeds, 33PSI for comfort with lower load/speeds. I run 215/60R16 @ 33-35PSI for daily driving in good weather, and air down to 30PSI front and 26PSI rear for ice/snow. On my SUV, the 315/75R16's are aired down as low as 8-10PSI for ultra deep snow, which produces a contact patch that is about 10" wide X15" long. This "climbs" on top of deep snow rather than dig down and high center.

[@peterscott2662]

@@mdocod While Floatation may be desirable driving low speed, in deep snow offroad, I don't think it's what you want operating on road, at higher speed.

WRC tires are almost more studs than rubber. Much bigger studs too as they don't care about road damage. Completely different design, application and requirements. Obviously, they have their reasons for going narrow, but I don't think we can just assume that under normal driving with consumer tires that narrow is always better. This video being proof of that.

@@RicHSAD2 you can install studs in any tyre. Would be interesting to hear why they went narrow. Probably it has nothing to do with the traction aids, but that's just my two cents.

[@lindsaydempsey5683]

Another great review. My summer tyres are 235/40/R18 on a Focus ST. My bias for winter tyres is towards a narrower taller fitment on one size smaller rim diameter, and same circumference as the stock tyres. These are cheaper than the full sized alternative, but that's a side benefit. The best argument I can muster for this setup is that the taller side-walls provide better compliance for the tread and better grip in that uneven surface situation which what you get with hard packed snow on Calgary streets where I drive. Hard packed snow and snow with ice underneath are the conditions that concern me most.

[@nicholasmccamis3706]

We generally don't get so much ice in Calgary. It's normally either very cold packed snow, fresh looser snow, or just plain salted standing water. There may be ice on the residential streets but I'm sure you know if you go fast enough for that to be a risk you've successfully halved the life of your struts.

Very interesting results. I would have liked to see testing on wet and dry pavement too since in our conditions that is about 99% of our winter driving conditions (once the roads are clear of snow.) The narrow verses wide tyre argument is more contentious in deep stuff whether its snow or mud off-road. I tried this experiment many decades ago when I went from a 265 to a 235 tire on a full size pickup (with a slight difference in tyre diameter) and I tried it on an SUV when I went from as 265 to a 255. My mostly subjective findings were the narrower tyres were more efficient in wet conditions but ended up with less traction on pavement. I didn't notice much of a difference in traction in deep stuff but again the narrower tyres seemed to be more efficient. These weren't objective tests since the tyres were different brands and two very different vehicles were used. I ended up preferring the wider tyres purely for safety reasons on pavement where the consequences of a misshap are much more serious.

[@gwot]

The theory of a narrow tire is so it can dig through loose snow/slush and get in contact with the pavement, where as the wide tire would float above the loose stuff and have less grip. You're basically testing on packed snow, might as well be testing on pavement and will probably have similar results.

[@ItsJust2SXTs]

Living in Canada here, driving a RWD car, 08 Magnum with the 3.5L to be precise, wider for the win! running 235/55/18 toyo GSI5 from 2015(the best I've ever had and still with a lot of tread left, i'm about 70% worn and no crack) instead of 215/65/17, did not choose the 18" wheel but I run 235/60/17 in summer. Wider for many reason: - road are cleared and it's not snowing every hours, even if it's snowing all day long with 20cm thick fresh snow it's nothing - if it's icy, wider tire give more stability - It's better to ride over the snow than cutting through like a knife so the underneath of the car will not hit the snow and make the car floating and draging - When braking wider tire help making that buldge in the front tire to make it slow even more, one thing I do is not hammering the brake for the ABS kick in, it's even worse. I slow the tire until it barely kick in then reduce pressure until it stop then reapply just before it pulse that where the most braking happen, with experience you can hear the snow packing in front of the tire it make a special sound. Over time you know the grip you have just by hear and feel. last year the ABS did not kick in much. Ice is trickier, glass ice is the worst to judge. I have never been stuck/crash in the 8 years I own that car, driving ESP/TC off on snow bellow 50km/h and keeping around 2000RPM from 1st to 3rd, over 50 I reactivate ESP, it save me once on black ice under a bridge.

A tyre that it the best for accelerating but the worst for braking is bizarre. You just would not expect that. Thank you for testing them against each other.

Well to explain the smoother transition into oversteer on the 275, staggered setups always reduce oversteer. And inconsistency with braking on 205 is simply that it's a different tire.

Great video. It confirms what we all learnt in high school physics; that is surface area does not affect friction (friction = Fr / Fr). I would have like to see dry handling.

Also, switching from a 17" summer to 15" winter, I notice a slight improvement in terms of turning reaction because of the loss of non-suspended weight. In any case, it's a good idea to go down in size during winter :)

I think it depends on what surface you drive on. Rather than the hard pack you are testing on here, I drive on pavement that gets snowed on. Some times the plows get it taken care of before I need to be in the road but most of the time they dont. I prefer a narrower tire to punch through the couple inches if fresh snow and get down to the pavement vs the wider tire that would want to float on top. I think your hard pack tests are totally different than how mow people drive.

I have 17 inch 225 summer tyres and 16 inch 205 winter tyres. I was thinking I should get 225s for winter too but now I'm sure I definitely don't need those. Thanks for the great video!

Great test as usual. I’m running 19” Michelin PS4S in summer, and as you suggested, a smaller diameter winter tyre (17” Hankooks). For me this is an excellent combo and keeps me comfortable and out of trouble in winter, but let’s me drive on the door handles in summer. Keep up the good work.

Wonderful test. I would love to see the same test but for "poor or marginal tire choices", such as all-season or even performance all-season, because that's what people use in snowy condition here in California, so I'm interested to learn how Californians usually end up in the snowy ditch.

So, in regards to traction, a narrower tyre has more weight per sq/cm than a wider tyre. That means a smaller tyre will dig deeper into snow, ice and slush than a wider tyre with a bigger contact area but with less weight per sq/ cm. When braking it'll be the opposite as a narrower tyre can't "grip" the surface as well as a wider tyre can. Same goes for turning, a smaller tyre has to carry more weight and becomes softer than a wide tyre. Great video 👍🏼

The total contact patch area is the same regardless of tyre width given the same weight and tyre pressure. You can't change the laws of physics! It's the shape of the contact patch that changes.

[@jackp-j1041]

Great video, a few things I'd like to see though - what pressures did you run each tyre at, and how does the performance change when you adjust the pressure? The reason tyres with tall sidewalls are popular/better offroad/snow etc is because you can run them at lower pressures than a tyre on a larger wheel with a low profile / small sidewall. And the reason skinny is better than wide when accelerating is becasue the longer footprint means the tyre "clears" its own path more effectively - say for example if the first cm or inch or whatever of the tyres footprint hasnt got optimal grip because its squishing or displacing the snow, the remaining fraction of the tyre is greater for the narrow tyre than the wide tyre. As for braking - the wider tyre is going to create more of a "bow wave", i.e. its pushing against more snow, which creates more resistance (which also makes it worse at accelerating). Another interesting point, on sand, vehicles without ABS stop better than vehicles with ABS, because of the bow wave effect mentioned earlier. It would be interesting to see if the same is true on deep snow.

Now we have snow and ice down, however these tyres are used most often on cold and wet surfaces. This would be the most interesting comparison in my opinion and I would think the wider tyre would do better there in most disciplines.

agreed

one of the more challenging aspects of winter driving is on the highway when there are slush buildups in between lanes, and one needs to make a lane change at those highway speeds. At those speeds, the slush buildup imparts a yaw moment on the car as one of the front tires plows through it. In this situation, a narrower tire presents less resistance, and makes the car more controllable.

[@mikemustang5488]

Excellent test! Great info. My takeaway is that going to a small size to save money on tires and wheels for winter isn't a bad move.

[@VickersDoorter]

40 years ago I had a 1965 Morris Minor on narrow Uniroyal radial tyres. I never ever got stuck nor lost control - even when driving through heavy snow or icy slush. Nowadays, all I see is people with low-profile mile-wide tyres, slipping, sliding and crashing, then complaining that Highways have not put enough salt down.

[@thebrowns5337]

Very interesting as usual. Another area where width (or rather aspect ratio) is hotly debated is on camper forums - people wondering if a wide tyre is more comfortable than a narrow on their VW t5/6. Looking at the pressure charts is something folk do with the wider tyres generally (not always) happy with lower pressures. But then there are discussipns around air volume and sidewall height. One owner did a video showing a road ride with the usual 205/60R16 vs 235/55 R17 but there are more variations VW Transporters/Californias can take. We need VW to lend you a California for a bit so you can test all the variations and settle this. VW campers are a huge market with keen owners groups and myself (and others) do mention you @tyrereviews in the forums sometimes 😊

As many are pointing out, there was no deep snow test, only a very thin pack and ice. As a North East resident with a background in motor sports, here are some observations about tire width. As we know, the total size of the contact patch is basically going to be the car's weight divided by tire pressure. Changing the tire's width changes the shape of the contact patch, but not the size. Within reason, the wider patch of a wider tire gives more side to side traction, aka turning. The longer patch may offer more longitudinal grip. A wider tire also has more surface area to dissipate heat, which helps out sports and race cars in warmer weather. In deep water or loose surfaces, the effects of the tire's footprint will manifest in more ways. In heavy rain or deeper snow, the narrow tire has to part less material moving forwards, before reaching down to a harder surface that should offer more traction. This is why a deeper snow test would have been really helpful. In water, the wider tire is basically displacing more fluid at the same speed, so it has more flotation and is more prone to hydroplaning, pretty much period. However on a loose surface such as snow or gravel, part of your braking performance comes from piling material up in front of the tire. Though, ABS can largely negate this, I think it is still a valid factor. Basically, I predicted the 225 would be the winner the moment I saw the physical tires and assumed that the 205 was a lower end model than the other three. For all the reasons he pointed out, I was correct. Had there been a deeper snow test and/or all the models been the same, the 205 might have won outright.

Hey Jon, any plans for a video on the difference unsprung weight does? I get that it’s more beneficial to cornering and acceleration, but the internet argues that it’s like 1:4 - 1:10 equivalent ratio to sprung weight. Would appreciate your input and actual track testing to quantify it as well as your subjective input. Keep up the good work!
