[@jamesferguson6583]

Tractors have tall skinny tires to minimise track width and maximise the surface area of crops

[@hummerdude2485]

Designing a narrow track tractor with wide tyres would be an easy achievement for engineers. It's all a fine balancing art

[@jamesferguson6583]

No there are still plants between the wheels when driving over

[@olliehopnoodle4628]

When I explain airing down to new folks (or their kids). 1. The lower pressure makes the ride more comfortable. 2. You get a greater foot print over rocks and such 3. Think of a balloon. Is it easier to pop a really full balloon or a deflated balloon?

[@Ronny_Dahl]

I like it!

[@PeterKnagge]

What confuses me is when i see things like this: skinny tyres no deflation - Mud crawler comp: kzbin.info/www/bejne/mJfdZ3mPbrmArZI Rock crawler comp: kzbin.info/www/bejne/epK0gHqCl7GlmNU (also if I was really to play the devil's advocate, talking about skinny tyres on sand yet shows a picture of a tractor on dirt!) I'm confused if there is that much difference between sand and dirt/mud, and using the example of the comp trucks, tractor, and tank, it would seem tall skinny tyres are best regardless of ground conditions or tyre pressure.

[@PeterKnagge]

At the risk of sounding like even more of a noob to you, very interesting 1st place tractor pulling tyre and tyre pressure tips: kzbin.info/www/bejne/h5vMZKinfNKsh7M She seems to be an expert and know exactly what she is talking about!

[@amaclach]

@@PeterKnagge mate - you obviously know better than generations of desert drivers. You should visit the world's deserts and educate everyone how they're doing it wrong.

[@mikewasowski1411]

Peter Knagge I’ve no experience in dirt but I still struggle to see how skinnies in sand are better. I realise pressure effects the length of your footprint. No arguments. But a wider tyre with the same length footprint as a narrow one has greater constant area. The greater the contact area the lower the bearing pressure on the sand. That goes further to reducing the amount it sinks and therefore the resulting “step” In front of the tyre as it drives. Really, is love to see a big set of fats vs real skinnies in a direct side by side on same car, aired down to same pressures up a dune, slowly. 2 gear low. 2500 rpm. See which get further to eliminate driving style and power. Both HAVE to be the same diameter though. Hmmmmm anyone???? 😬

[@UFOGEORGE]

Man... I come from Crete. A whole world away. However, I watch a few Aussie 4x4 channels which are all good or decent. I must say that your area is probably the best in 4x4 experience which makes your input all that valuable and helpfull. All the guys I watch are good and aid the community and the adventurer. What I must stress in my experience in all areas (which is quite substancial) and being an engineer, is that you are the best in the field. Easy to understand through good and simple relay of knowledge, experience and expertise, easy going, pleasant, polite and analytical. I feel lucky to be able to watch your videos, I have a cracking time and to say the least, I am much obliged 🙂 I don't t know how else to relay my congratulations to you but I hope I managed. Cheers !

[@keswicktours]

I'm now 8 weeks in Iceland with my Defender running on BF Goodrich M/T KM3 255/85R16. I arrived with full highway pressure of 36 psi and started to discover Iceland on gravel roads, lava sand, mud and rocks. As I often had to use central diff lock and L gear I was able to manage all kind of tracks. BUT when I tried to cross a snow field I had no chance. Listening to the locals they recommended to reduce the air pressure down to 15 psi. What a game changer. I was able to cross the snow field and simply continued with the low air pressure through the highlands. As the speed is low anyway the tires don't heat up and manage all previous mentioned road conditions much more comfortable. Just the roll tendency increased but so far nothing critical. I can completely underline what you explained, except I have no trailer. Greetings from 🇮🇸, Bernd

[@mrfixit____3651]

Another thing about bouncing on rocks is if you bounce and your tires leave the ground then they have zero traction and stop trying to push you forward then they land and the downward force gives them lots of traction combined with wheel speed. SNAP! there goes an axle or u-joint.

[@johnxander6305]

The fact is that if you air down when driving a unimog, you should be airing down every other car. Even when your driving a truck with portals and 40’s the difference in traction when you air down is phenomenal

[@Equiluxe1]

Myth number eight,Tractor tyres are narrow, not for most field work they even fit twins on front and back for some work,narrow tyres are used for crop row work so you dont crush too much crop wide flotation tyrews for cultivation so that you don't compact the soil too much.

[@thewhaleylife3013]

@Battle Fiercely my pops works with trains. They have horrible traction.

[@isaachigham3516]

Row crop tyres are not good in mud! Width and tyre height is important. Skinny tyres on the beach is an absolute yarn. 😂

[@SiCrewe]

If we're basing our opinions on empirical data, how come every dune-buggy and sand-rail ever built has skinny tyres on the front and honking great wide tyres on the back? In Britain, a lot of the countryside has soft, peaty, ground and it's pretty common for game-keepers and estate workers to drive Land Rovers with extra-wide wheels to aid with flotation and to avoid tearing up the land as they drive. I think the whole "you don't need wide tyres for sand" thing is more that they're not critical but they ARE beneficial.

[@Equiluxe1]

@Battle Fiercely Wide tyres are essential for flotation and traction on soft ground look at any earth moving equipment for that matter look at tank tracks most modern ones are fairly wide in order to get the lowest possible ground pressure, they used to use narrower one in the past but that was more to due with slewing forces when making turns it was a compromise, The T34 had wider tracks than most of the german tanks so that they did not sink in the soft mud. Google pictures of tractors, most have wide tyres the only use for narrow tyres on tractors is row crop work.

[@jarradblair1793]

True for flat soft soil but in the steep hills gravel and sand tractors are almost universally fitted with narrow tyres the wide flotation tyres simply can't get enough purchase to drag a seeder uphill I'm not a full time cropping farmer but even I know this and have 2 sets of tyres wide for the soft delicate and boggy soil and narrow for powering up steep hills and through the hard stuff

[@CliveWebbAustralia]

I've been driving 4x4s, off road for 40 plus years. As far as skinny v wide tyres, I've had both and driven all kinds of conditions, in most popular brands of car. The difference between them, depending on the vehicle, in most cases, is so small that it's not worrying about. The correct tyre depends on two things, the vehicle you own and what you want to achieve. One thing to keep in mind is that an under powered vehicle will usually perform better on a skinny tire. Tyre pressure is the be all and end all for all situations. The correct tyre pressure for all conditions is... Totally dependent on on the environment, the vehicle and can change from day to day, depending on the weather. There only draw back with mud tyres that I have found is that they can be noisy on the bitumen...

[@adamkrawczyk6382]

I would add that skinny tired cars tend to be older and more often than not, much lighter. Plus usually they tended to have a larger diameter than optional fatties stock vs stock, so there are a few variables there.

[@crusty181]

Ummmmmm. That make zero sense. If "an under powered vehicle will usually perform better on a skinny tire", then common sense and a kindergarten education would stretch that to any vehicle will perform better on a skinny tire.

[@tenskeeze]

I'd like to add saving on fuel on skinnys vs Fatty's lol Rolling resistance. You cut through most terrains instead of pushing through. You don't slide on rocks climbing up. And if you need to float air down. Skinnys all the way

[@omegabulldog5001]

I carry loads and cargos on my Hilux and I find that wider tires with the PROPER pressure makes a whole lot of difference when I am fighting uphill on a rutted and wet track.

[@FloridaTwoWheelAdventures]

Any of the round rubber things you use under your vehicle work better if you call them “tires” especially since the “i” is skinnier.

[@wademan7180]

Onya Ronnie 🤙🏻 I use to believe muds we’re no good in sand years ago too! Nar mate they’re all good !

[@amaclach]

They have stiff sidewalls so don't elongate as well as AT when aired down. They also suck on wet roads, they're noisy AF, and wear very quickly.

[@tombuckle9742]

even my 404 unimog on 42" v-tread tyres needed to be aired down

[@psyekl]

Thank you for these videos. I just upgraded from a less capable 4x4 for more adventurous journeys. While not a complete novice, I definitely need an education and this channel is pure gold.

[@anthonywhitney634]

I've had it explained to me that skinnies are better for following reasons: mud- skinnies cut thru to firmer base and get traction, rock/dirt- narrow tyre means vehicle downforce concentrated on smaller area which equals greater traction on that concentrated area.

[@michelt4390]

Dropping air pressure destroying tires: the problem arise when driving too fast. Sidewall flex creates heat... and is bag for tires

[@spedon2wheels267]

That’s why we have compressors

[@KTMcaptain]

I've lost a tire due to heat duning in the sand at 10psig with internal beadlocks. melted a hole right into the sidewall, then some more by the time I got out of the sand. I even melted a dirt bike tube running really low pressures in the dunes, but rim locks kept it together.

[@KTMcaptain]

@@spedon2wheels267 Why would you air down just to air back up? Driving off road with too little air can quickly destroy a tire due to heat. Doesn't have to be on road. It also doesn't have to lead to an immediate failure. The heat cycles can cause long term issues with the tire.

[@MCQBushcraft]

I run a wide tire and mostly tackle rocks and snow. We get over one meter of snow here and obviously that's not drivable, but when its about 50cm and it starts to get very challenging the wide tires make all the difference. If you look at all the winter forest machines and trucks the tires are gigantic and wider than my shed and the tracks are the width of the entire machine. Floating in deep snow is the only way to not get stuck. Thanks again for another great video 📹 👍

[@samuelorhjaltalin9042]

When it comes to floating in snow wider isn't much better. Most of the float and the traction comes from higher tires, but there's a sweet spot ratio still. (Like 42x15" is pretty good, but 44x18.5" (DC) is slightly better, even though both tires have about the same height.) when it comes to floating the width of the rim also matters. I ran 44"x18.5" DC on 18.5" wheels for years and it worked very well (especially in side slopes), but fuel consumption on my 42" tires was way better and still had similar results in traction. I'm now going for 46x19" on 20" wide rims and I'm curious how it will perform. A friend of mine did a test with 35"x18" (Where on earth he found those tires, I have no idea), but it absolutely sucked in snow. Even regular 35x12.5" tires worked better...

[@donvape336]

On the process of modifying my 4runner. After watching this going with yokohama g003, which I have been eyeing for a while. I'm in the USA desert southwest.

[@tenskeeze]

Just air down for flotation don't need super wide fuel sucking tires just tall skinny AT or MT. Hard tire no matter how wide aired up high the skinny would float better and better fuel consumption so 🤷🏻

[@robmacca67]

What I think u need to do is a Tyre size comparison. Get 2 of the same brand and Tyre type with one being skinner than the other but both having the same circumferences. Like u should compare a 255/85/16 Tyre to a 285/75/16 Tyre- both are basically 33inch tyres with the only difference being the width. This would be an interesting comparison in all types of conditions

[@samuelprentice1305]

This would be great!

[@robmacca67]

After looking online for Tyre Sizes - a better comparison would be a 225/95/16 vs 285/75/16. This would be a good comparison between a skinny vs wide tyre as they both have the same rolling circumferences.

[@lastknownlocation8760]

Hey Ronny, just a tip, because I’ve been arranging repairs on these since 1986, if you want your Engel to keep working, you should cover it with something. It’s not designed as an all weather outdoor unit like a Trailblazer etc. The led display will be the first to go followed by the electronic control panel, followed by the other bits. Keeping it out of the sun will also make it a lot more efficient.

[@kyleb5518]

Gone Bush I’ve had mine out on the back of my pickup bed for the last 5 years (uk) loads of heavy rain, it’s held up fine ismit more the heat that gets to them?

[@lastknownlocation8760]

Kyle B yep, the heat will just bake the electric controls. Kyle is yours a 5 year old fridge or an earlier model? They will still work in the weather (older models more so that the newer models) and they’ll still last a while, just not as long as if they are covered. Parking a fridge in the sun doesn’t make a lot of sense anyway. Especially one with as little insulation as an Engel.

[@mohamedalihebboul2214]

[@speedygonzales9993]

Good job on the tyres mate. I also would’ve explained aggressive side walls protect your tyres when at low pressures whilst driving over rocky terrain. Love your work🇦🇺🤠👍🍺

[@mtnboy6201]

Much appreciate you Ronnie !!

[@Splagnate]

One thing I would like to add which I’ve noticed with some of the new MT’s is that well here in the US anyway is that a few are going for looks over usefulness. They’ll have aggressive side treads on one side and not so much on the other. It gives you a choice for looks but only one sidewall is going to give the extra bite you need versus a proper MT with bite on both sides. Something to check out whenever buying a new set.

[@michaelnugara1]

[@FreedomWorldTour]

Perfectly explanation of the narrow sand tire!

[@wirebrush]

A good explanation, but not perfect. Flotation on sand is a matter of PSI. The lower your PSI (pounds per square inch) the greater the flotation it's simple math. Contact area times psi equals vehicle weight.

[@Central_CoastRotors]

Great info Ronny....!

[@artieshell9205]

Perfect!! Thanks!! Also… tractor tires with narrow tires are done that way to fit between rows of planted vegetation. Wider tires would ruin their harvest . 😉

[@gavinchapple825]

Keep up the good work Ronny!

[@seanflanigan4508]

(From another West Australian). With respect to skinny vs wide off-road. When airing down, the aim is to get a longer footprint, not a wider one. Apart from increasing the size of the contact patch, and therefore reducing the pressure per square inch on the ground, there’s a key reason for wanting length over width. And that is longitudinal traction. Ronny’s tyre aired down on a rock demonstrates this perfectly. Especially climbing up rocks, this ability to mold to the edge of a rock equals grip and traction. There’s a lot of tyre in contact with the rock. Highway pressure in any tyre, skinny or wide prevents this from happening. I personally prefer skinny, but Ronny’s logic is sound and backed by a lot of experience. And like Ronny, tyres with decent side wall tread blocks help in every situation too.

[@mechanic7430]

Great comment. I sprayed my rum everywhere when you said rocks just send it🤣👍

[@mikemcburney8890]

The example of track width on tanks proving that wide tyres don't give better flotation on soft ground is a little iffy, Ronny. Bulldozers that operate on swampy ground use wide tracks (swamp tracks can be up to a metre wide) and dozers that operate on hard ground use quarry tracks which may be less than 400mm wide. Using swamp tracks on hard ground reduces the dozers' pushing ability dramatically. So, in that case, ground pressure equals load carrying ability.

[@JB-pc7mg]

Very helpful thank you !

[@rudedogii]

Skinny tires for mud, dig down to solid surface rather than floating on a layer of mud. See R2 Agricultural tires also known as "Rice and Cane" tires.

[@customcraftnadventure]

I hv been using 235/85r16 muddies. Wonderful on sand. I do agree it is harder to find traction on mud so I use more -ve offset rims to find more side traction. Seems working well.

[@off-roadrcaddict4572]

I always used tall narrow tyres on my old suzuki Samurai and it worked really well on all surfaces. Need to look at vehicle weight as well.

[@Phos9]

Tanks that handled fine in the deserts down in Africa needed wider grousers to handle the mud that bookends the winter in Russia and the more temperate climates in France.

lmao the low profile landrover tire..

[@SiCrewe]

Oddly enough, I was looking at this yesterday. Mate has a Disco 3 with 20" (?) wheels on it and he's looking at putting some better wheels/tyres on it. We took the wheels off one side and put a couple of 16" wheels with 33" tyres under the wheelarches, just to see how it looked. It looked... weird. Even though the tyres barely fit under the arches, the wheels look comically small. The Disco 3 is pretty heavy so I guess LR could argue that they HAD to fit 19" wheels so they could fit big brakes but, let's face it, if Toyota can get a 79 to stop using brakes that fit inside a 16" wheel so could LR if they wanted to. Pretty sure that the main reason LR fit big wheels and low-profile tyres to their newer cars is simply a design choice.

[@kadmow]

Yep - A dilemma Roadtyres (esp on huge rims) may slice the sidewall (pinch - on rocks / ruts) or crack the sidewall if lowered too much at all.. not a good recipe for anything off Asphalt. Too bad a lot of Luxo wagons have "huuge brake disks -for racing - and can't take smaller rims, and no guard clearance (or lift kit - due to very complex suspension / monocoque ) for bigger tyres. Shows flash ain't everything. j

[@JayGuitars1]

Great video!

[@mikecheslock3542]

I live on the east coast of the U.S. and have a 2012 Chevy Suburban. It is my daily driver and weekend beach wagon. I've used Mud terrains, ATs, and even regular Light Duty street tires on the beach. Yes, ATs are a little better than Muds on the sand, but not enough to sway a decision on which to buy. When choosing a tire, you need to look at everything the vehicle will be used for. My truck spends 90% of its time on paved roads and the occasional weekend on the beach. I prefer using a wide AT tire because I don't even have an option for any type of harsh terrain near me so stronger sidewalls aren't needed. An AT provides a quieter ride than a mud tire. When I lived in Las Vegas, I would run a Mud terrain because the desert cactus was notorious for puncturing tires, and the extra thickness help, but the needles could go through even those. I currently have 305 series tires on the truck and the truck is capable of staying on top of the sand without airing down. I save the airing down for if I actually have issues, only because the previous owner went and put 22 in rims on it so the tires don't have a lot of sidewall. Once it's due for a tire replacement, I will be switching to a smaller rim (either 20s or 19s) package to give me more sidewall and allow me to air down without being concerned.

[@worldwithoutwar4396]

Great Video..and usefull..Thanks

[@pipamusa]

I bet the thing with wide vs skinny is more like somewhere in between but the range of tyres people use is close enough together to not make enough difference. You would have to go to the extremes to really see the difference. There’s probably a compromise on either end and something in between is ideal. The biggest gains are from pressure then height as both give the longer “track”. I’ve been sand driving in a Nissan xtrail and the only reason I’ve been stuck is from clearance and getting crossed up

[@4WheelingInNSW]

Another good one Ronny 👍 Many good tips and points there champ. One thing though regarding the tractor tyres and why they use narrow tyres ? That is purely and simply so they can run them between their crop rows without squashing what they’ve planted and if they had wide tyres, they would have to have wider gaps between the planted crops and therefore end up with less rows per paddock, less produce means less $$. Anyway keep up the good work mate 😉👍

[@chrisnorman1183]

Awesome Ronny, As a newbie 4x4 these points were great. Cheers from Tassie! Edit* P.S we have snow :D

[@philippgeisler4590]

Some observations: 1) HT vs AT on sand: I tested 235/70R16 HT (Giti) vs 245/70R16 AT (Goodyear Wrangler) on a more or less underpowered 2.4 l 4x4 (one side HT, the other AT) some years ago. The AT dug more than double as deep into the sand as the HT with same pressure and the imprint of the HT looked far cleaner. I didn't make a comparison to MT. However, the maximum height I could climb on the same dunes was more or less the same (comparison full HT vs full AT) with a slight disadvantage of some meters for the AT. Since I live in Atacama, a lot of vehicles here are built purely for driving in the dunes (mostly Suzuki Vitara). Those guys often go for pretty wide tires without aggressive pattern (something between a slick and a HT). I can just watch them from below, so it seems to work. So, in order to take your debunking of tread patterns and tire widths more serious, I would love to see you trying the same dune (needs to be something dramatically bigger (100x), than in the video; something like Medanoso) with different tread patterns and tire widths and an underpowered vehicle. PS: area is length times width. You want as much surface on the sand (or snow), as possible. There is a limit you can achieve in length and then you can only increase further by adding width. 2) Pinching tires with low pressures: I have the impression, that tires below 10 psi are far more endangered to get pinched by a rock than tires with 15+. At least both tires I pinched during the last 5 years have been punctured with very low pressures (

That tank Gunner was F&$k*d! Lol.... Great vids mate, here in 118f' lake Havasu, Az. USA!

Yeah, I saw that. Bet his ribs be hurtin'.

I love watching y’all Aussies more than our states guys. If a Aussie thinks it’s bs, y’all say it’s bullshit. If a US guy thinks it’s bs, well we candy coat over sensitive feelings. Stay true Aussies, we love you here in Tennessee

[@janeblogs324]

Please watch Dash cams Australia. You will see a really difference to USA/Russia. Boy do we hate bullshit and injustice

We have little mud in Norway but every educated driver here knows that skinny tires are best for snow due to less resistance,,, that's why I have skinnier tires on 16" rims for winter and wider tires with 18" for summer on my Jeep WJ,,, also, most ppl have dedicated snow tires with softer rubber during winter months (it's mandatory), but many 4x4 drivers us also Mud+Snow tires, and then often studded.

[@RockmanDash]

I wish snow ❄️ tires were mandatory in my State. Lots of people don’t buy them and slide all over the place

[@dubious6718]

My winter and summer tires are the same dimension and I have no problems on snow 265/70 r17

THANK YOU SO MUCH for this and part 2--- I'm new to 4 wheeling-- and will be buying a lexus GX470 (softroader as you call it) and I've learned a LOT from you... thanks again.. (and NO I'm not going to be rock crawling..). I am a REAL softroader only.. :)

Hey Ronny, one thing that I really think would be great for you to explain which would aid in understanding tyre pressures especially in soft terrain is the weight capacity of that ground. Airing down spreads the weight of your vehicle over much more area of that ground creating much less pressure and therefore allowing some horizontal resistance in the ground that provides forward traction versus a hard tyre where all the grounds tractive capacity is providing vertical resistance with nothing spare to provide horizontal drive, which leads to you getting bogged. All ground you travel over has a certain amount of capacity and in 4Wheeling our aim should always be to maximize horizontal traction. The best way to do that is to minimise vertical pressure demand on the terrain.

Had a clown at a tire place try to sell me 20" wheels and tires for my Prado. Just laughed at him when he said it would be better for off road.

A little comment with not much experience but some knowledge; In deserts where sand gets eroded by high winds, sand has way lower particle to particle friction, and something tells me that's where the problems with MTs start.

I was just wondering about the reasons behind lowering the psi on the trailer tires because the plan is to build myself semi-offroadish camper trailer for family vacations. At first I wasn't really considering either way to be the "right" way, but this explanation makes sense, so it will have lower psi also then. Just the info and explanation I needed at this moment, thumbs up.
