Why Are Bike Tires So Confusing? | Types & Details Explained!

[@gcntech]

Do you prefer clinchers, tubulars or tubeless? 👇

[@katcorot]

Clinchers, I like simple old school things, that just work. And don't require a special degree to keep working

[@ciaoneef]

I rode a bike with clinchers for about 7 years and only ever had one puncture. Recently bought a new bike with tubeless-ready rims & tubeless tyres, but I'm thinking of switching back to clinchers because I don't like the idea of having to replace the sealant every 6 months...

[@KenSmith-bv4si]

I have puncture protection tyres on my mountain bike and cycled over broken glass with issue, road bike I prefer tubular though go tubeless if not need sealant as hate keep top up, had a puncture on tubular once but where I was went like 43mph or 63mph down a hill to finish about a mile away on the ride

[@jeremynorth]

Yep

[@sventice]

Nice video: clear, unfussy, informative. Pretty much sums up why Alex is one of my favorite presenters on GCN. I vastly prefer clinchers with tubes. I tried tubeless and didn't like them. It's partly that I like slightly higher pressures, partly that tubeless performance isn't actually noticeably better (they're really not even that much more puncture-proof), and partly that they're unreasonably difficult to get onto wheels, but mostly it's the sealant; that stuff is sticky and disgusting.

[@donaldduck5731]

I used to take my road bike out for a puncture repair session. Since switching tyres to Schwalbe Marathon Pro’s I’ve been going out for cycle rides.

[@brankelly1921]

A curated video worth at least a $100 for free here on KZbin. I really appreciate you guys for putting this up. Thanks so much!

[@DavidWhiteOfFleet]

Small detail you missed. Tyres started off on wooden rims, as you said, but they weren't there to give you grip. Their main job was to tie the wheel together, hence "tyres", and to be durable.

[@gcntech]

Thanks for the fact!

[@mynameisyasser]

Wow, thanks

[@brian3937]

the word tyre or tire appears to come from the word attire, in the sense that the wheel had been dressed in something to protect it.

[@DavidWhiteOfFleet]

@@brian3937 yes, there does seem to be two schools of thought about that. Although in a wooden wheel the tyre does literally tie it together, without the tyre the rim would be separate pieces of wood.

Clinchers for me but it makes a big difference which tyres/tubes you use. My current road bike I’ve done over 8000 miles on and only had two punctures, both caused by huge potholes. I have decent tyres on this bike. Whereas on my older road bike I used cheaper tyres and used to get punctures all the time. If you invest in the right tyres you shouldn’t have any problems using clinchers!

[@gruanger]

I bought a cheap chinese bike. The tires that came with it popped from punctures every time I road, I just thought that was how it was with road bikes. I was a complete newb. I started looking into it and realized I was just a fool. I bought some better tires on amazon and have never had a puncture since, it is crazy how big a difference it is. I am not a racer, I ride on regular roads, so knowing I can just go out and exercise without wasting time and money is way nicer than going really fast.

[@stevek8829]

​@@gruanger you learned quickly and who would have thunk it, not a fool. ✌🏼

[@PavelSavyhin]

My punctures are either because of the piece of glass or because of bumps. I had about ten in the last half a year and couldn't imagine how changing tires can help.

[@gruanger]

​@@PavelSavyhin I live in Arizona with thorns, glass and other sharp things literally everywhere on the side of roads. I bought puncture resistant tires that have layers of puncture resistant materials. I am not sure what it is and it makes the tire weigh more and is thicker, but I went from literally daily flats with large thorns sticking out or glass, to not a single one since

[@gcntech]

Tyre choice makes a huge difference 🙌 Do you ride purely on the road or are you mixing in some gravel?

[@roblillicrap9014]

Tech team doing really good work on these deep dives!

[@larrylem3582]

I think clincher tires comprise tube-type tires as well as tubeless tires. Tubeless then breaks down into hooked and hookless rims. When mentioning tire sizing conventions, it would have been good to note that MTB 29ers are the same as 700c (ISO 622), 650b (584) are also called 27.5, and that 26" tires (559) were the standard MTB tire size prior to 27.5 and 29ers.

[@cmarnold78]

That's GMBN's jurisdiction though :)

[@danielhertercasagrande1686]

@@spinnetti Indeed they are different, I think some people think "close enough" for non-critical applications 🙂 Lol, for cyclocross it might just be critical enough

[@alyoshakaramazov8469]

After a lot of experimentation, I use a tubeless 30 mm tyre with an insert for long distance road riding (2 to 9 hours at a time). I came up with this because it gives me more comfort for long distance rides and has not ever needed me to repair a puncture while on the road, and it provides the most safety against a catastrophic failure. Every few months I have to top off fluid or change it out. In case of a catastrophic tear in the tire. the insert will keep the tire on the wheel (and keep me upright instead of sprawled in the middle of the road picking gravel out of my wounds) and allow me to ride on the flat tire for some time, although this has not happened in 1000 miles of riding since I switched to tubleless. I have seen the white juice leaking out of tiny holes in my tires while on the road, which would have meant stopping to repair or replace a tube in my previous setup. On a 200 km ride I don't want to have to do that because I could run out of daylight if I were to have to stop to repair. Also, the weight of the spares tubes and repair kit can be felt after about 100 km or so. I am 70 years old so weight and the amount of time I am on the road matter quite a bit. I am using a light weight tire to compensate for the slight increase in weight from the insert and the fluid, which is still less than the weight of inner tubes and a repair kit. The only down side is that the tubeless tire is quite difficult to get on an off my wheel, especially with the foam insert. I get around this problem by compressing the foam from the sides with wood working clamps, as the special tools for this job don't always work well, especially since the fluid can cause the bead to stick fast to the wheel. I won't go back to tires with tubes because I used the "call the wife to come pick me up" card too many times.

[@emmabird9745]

Thanks Alex. Is the sealant in tubeless for the rims, puncture protection or is it the spoke holes? Do we need special rim tape for tubeless? Re your question, 4:05 you talk about width, I didn't get the clue. As for winter tyres, the critical measure is the transition temperature for the rubber, ie the temperature below which it is solid and not flexible. Foe car tyres I have found Pirrelli far too "summer" for a UK winter and maybe why so many cars end up in the ditch. More geekie stuff please Alex (or are you really Bob in disguise?).

[@sbccbc7471]

The sealant is for punctures at the tire.

[@fitzt70]

Look at the graphic @4:02, you will see a small LEGO piece fly by.

[@emmabird9745]

@@sbccbc7471 I am not convinced. If it was purely for punctures then it wouldn't be necessary (unless tubeless are really fragile) and we wouldn't see absolutely everyone (on youtube anyway) putting sealant in their tubeless.

[@gcntech]

Hi Emma, the sealant is for the puncture protection, as you get a puncture the sealant should clog that hole and keep the air from escaping 🙌 Skip to 04:00 and the clue is there for you? All the pieces will click together and you'll get it 👀

Haven't tried tubeless yet for road. Don't like the idea of spraying sealant all over me/my nice bike, and though I'm sure it's better now, too many stories over the years about it not being as helpful for narrower, high-pressure tires. Made the switch over a year ago on my commuter/gravel bike and I love it. Less flats to/from work and more comfortable on the crappy roads I have to ride on. That bike has fenders pretty much year round as well so no worry about sealant spray when there is a puncture 🙂

Hi Alex, great video and well presented👍. However, I must take issue with your assertion that the pneumatic tyre was invented by John Boyd Dunlop in 1887/8 as it was originally patented by a Scot, Robert William Thomson from Stonehaven, in 1846. Dunlop did commercialise the pneumatic tyre though and it became the global brand we have today.

1:10 Wait. Didn’t you [GCN Tech] say in an earlier video that solid (steel/metal) tyres/wheels have lower rolling resistance than pneumatic rubber ones?

[@JMcLeodKC711]

Alex, great video. I was wondering if you could settle a debate I have been having with a fellow rider. On some tires, the manufacturer will stamp/emboss a rotation arrow into the sidewall. I argue that it is critical that you mount the tire based on this. My friend says otherwise. Also, I have seen some tires that do not have a rotation arrow stamped in. I assume these are symmetric.

[@gcntech]

Hi John. Yes, directional tyres must be faced in the correct direction, otherwise you won't be getting the benefits of its construction in regards to grip and rolling resistance. Tyres without directions however are usually cheaper and it won't matter which way you put them on.

[@bateriayvr8988]

Wouldn't mounting a tyre that has a directional arrow backwards basically be a major loss of speed? The rolling resistance on that must be huge, given that the tread pattern is intended to give the best forward momentum going in one direction! That would be so counter-intuitive LOL

[@GCNalex]

Hey John, thanks for your comment. The rotating direction will help the tyre work at its best and its how its intended to be used, however i must say i have never been able to notice a difference on the occasion i have managed to get it wrong. The majority of performance comes from the rubber compound and the pressure.

[@10ktube]

I'm a performance rider, and I bit the bullet on a set of Tannus tires a couple years ago. They rode rough, and I was losing efficiency, I was 7% slower, or needed 7% more watts, which is a lot. I didn't care, it was on a training set of wheels and other than my ego being damaged, I didn't really care. I carried nothing with me other than a very small multi tool. No pump, nothing. And, I didn't ever think about hitting crap in the road. It was really enlightening. But, the performance irked me, and the rough ride. If we get there, sold, take my money.

[@chazmuska]

My Trek FX4 shows TLR....is it worth it to convert to tubeless? Has anyone done that before?

[@spinnetti]

It occurs to me, that given the rims for "tubs" are a lot lighter than clinchers, why not combine the best of all the designs? Do a sealed tire with no tube on a tubular type rim and a bit of sealant (glue on I presume).. would have all the advantages of sewups, but even lighter. I guess that's what hookless attempts to achieve which has the benefit of no glue and lighter than clinchers but easier to repair than sewups. hmm. I think I just talked myself into hookless lol. I also learned from this that 1 bar does not equal 1 ATM bafflingly. 1 bar is 14.5psi whereas 1ATM (seal level at standard temperature) is 14.7psi.

[@zeemon9623]

Calling the tyres / rims 622mm (or whichever other size it happens to be) is objectively the best way to do it. It always corresponds to the actual measurement and is the easiest way to see what is compatible. But it can't be that hard to get people to use the proven superior system of measurements. People will quickly adapt the most logical and easy to understand system any second now.

[@genewhalen9264]

Is there a maximum ratio between internal rim width and maximum tire width?

It's not clear to me though if switching between clinchers, tubulars or tubeless is also going to change the actual performance of the bike. Do one type go a little bit faster than the other?

[@johnwestwell2241]

Most pro teams have switched from tubular to tubeless in the past two seasons as they feel there is a slight performance advantage - tubeless tyres are reckoned to be slightly faster, and being able to be inflated to lower pressures, more comfortable. However, the big advantage of tubs was the ability to continue riding on a wheel after a flat. The tub would remain stuck to the rim and would allow the rider to keep riding, albeit slowly, until the team car could get to them. With tubeless, that isn’t really an option.

Yes, it's using the 622 mm rim like 700 of 28 inch. The 29 refers to the outer tire diameter, which is bigger if the tire is wider. 27,5 inch mountainbikes are using the long existing 584 mm rim (also known as 650B) and 26 inch MTBs use 559 mm rims
