I feel like you guys forgot the most important aspect of tire width. On smooth surfaces, thinner tires at high pressure are the fastest. But since not all roads we ride on are perfectly smooth, the vibrations, bumps and reduced comfort are mitigated by wider, less pumped up tires, resulting in you going faster. Some manufacturers are trying to claim that wider is always faster due to less rolling resistance, which is definitely not true. However in reality most people will go faster on 28 or 30 mm tires since we ride on imperfect roads.

I'm currently running 32mm on my bike, and they are quite comfortable to ride on.

@neil7769 3 года назад

One really important factor that everyone always ignores is rider weight - if a 25mm tyre is optimal for a heavier rider in a given set of conditions, a 23mm tyre will be for a lighter one (etc). I'm 64kg and run 23mm on 19mm internal rims (they measure 25mm fitted). On my tubs I use a 25mm on the back as they measure the same as the 23mm on the clinchers (incidentally, remember that pros are still running tubs mostly when they are preferring 25mm over 23mm). I've tried wider tyres and they were slower (and felt slower too).

@wenschobert 2 года назад

I have to disagree here on one important point. There is a certain point where weight starts to benefit higher pressure and therefore thinner tires. at 100+ kg (and I know many riders having this weight and experiencing similar effects) you deform your tires so much, that a wider tire (since you can't put as much pressure in there) will slow you down. Never tested it tough, all anectodal...

@neil7769 2 года назад

@@wenschobert Hmmm.. I wonder if this is just down to getting the inflation pressures correct? You could always run a wider tyre at a higher pressure - not as high as in the narrower tyre, but high enough to make the deformation the same. Unless you are over the maximum pressure with the wider tyres?

@neil7769 2 года назад

@@wenschobert I see what you are saying, but in theory I can't see how it makes much sense to run a narrower tyre if you are heavy, just because you can supposedly inflate it to a pressure that allows relatively less deformation than a wider tyre at its maximum pressure. It should be the case that the wider tyre can be inflated enough to allow the same or less deformation. I wonder if this is just a hangover from a time when everybody wanted to inflate tyres as hard as possible, and the maximum pressures printed on narrower tyres allow for less of a safety margin than the ones printed on wider tyres.

@makantahi3731 3 месяца назад

@ccus944 2 года назад

One mistake they made is using the recommended tire pressure of the tire manufacturer instead of the wheel manufacturer..…the tire manufacturer doesn’t know what type or size rim you are putting their tire on…you should go by the pressure recommended by the rim manufacturer….in this case, running the tire at 85psi exceeds the maximum pressure designated by Zipp for the new 404 hookless bead rim of 73.5 psi…with today’s carbon rims, it is important to check the internal width of the rim, size tire they are designed for, and the max tire pressure specified(for carbon rims)…Zipp has a detailed tire pressure chart where you fill in your specs and it calculates the recommended pressure, and will even recommend if you should go to a bigger tire size based on your variables….something else to look out for - some tires are not compatible with hookless bead rims…ENVE has a running list of specific tyre brand and models that are not compatible with their hookless rims….I find 25s to be fastest…the fastest road tyre available does not even come in 28…so that makes sense to me….I have fast(low rolling resistance) 25s on my fast bike, and 28s on my bike I use for base miles/easy days…I don’t care about rolling resistance on that bike…for base miles/easy days, low rolling resistance tires do not make sense…you won’t know the difference at those speeds…whatever you choose, above all…have fun!

@petermyers4409 2 года назад

I ran 23 with tubes from 2013 to 2020, simply because that's what my bike came with and I was very much an occasional rider. Then I spent a summer working in Ireland and on terrible condition ( but beautiful) roads, I started wondering if I could be more comfortable and watched a GCN vid with Si explaining ways to improve comfort so I switched to 28. It's so much better, more grip more confident. I actually feel like I'm going slower but the times on my regular runs show I'm not. The bike is noticeably heavier when I pick it up. Not really noticeable when I ride it however. So glad I made the change. Thanks to all at GCN

@pflichtprogramm1 2 года назад

Interesting to see that, great summary! Personally, I will definitely stick to inner tubes for the sake of practicality. I'm riding my road bike unfrequently, so maintaining the tire pressure would be an 'additional' work. Also, having started to go road cycling with inner tubes in ~2008, switching to tubeless would lead to at least GBP150 cost of investment (after deducting income from selling inner tube wheels). However, being limited by my bicycle frame in terms of the rear tire width, I might one day switch to tubeless at the rear tire: Comfy ride at a decent puncture resistance. Plus, I wouldn't need to buy another frame to fit in a wider tire.

@franco992 3 года назад

For what it’s worth, having tried various tyres, I suggest buying good quality tyres (high TPI count) for comfort and speed on UK roads. No need to go very wide or run very low pressures. I’m currently on 27s with 300TPI and they are terrific. I’ll be opting for the same tyre but 25s when the time comes.

@s.j.5850 3 года назад

Very interesting video that leads to more discussion about the subject of tire width. Aside from racing how much of a perceivable difference does tire width & pressure can be felt? I would also like to know what happened to the tread that use to be on tires? Once upon a time bicycle tires were not as smooth as they are today.

@colinfisher2463 3 года назад

My preference was 28's until I accidently ordered some 32's to replace wore out tyres. On the Cumbrian roads I cycle on the extra width means extra comfort against the poor surfaces we have. Little slower if sprinting from slow speed and a couple of watts down on the 25% passes otherwise I feel I have more comfort and control.

@davidweissmann8069 2 года назад

Road bikes have a weight split of ~ 60/40 % rear wheel load / front wheel load . One could use a larger tire up front and have a safer contact area , more comfort for the bumps we encounter. or pressure consideration if both tires are the same width , the rear more pressure . See" Frank Berto's tire pressure chart" for some more input on this topic.

@gruensein 2 года назад

Except that power and speed are not linearly related since most of the resistance is aerodynamic drag. So, it is not quite so simple. Beyond that, while I appreciate little tests like this you really cannot draw any meaningful conclusions from this. The environmental conditions (wind, temperature etc.) are not controlled, there should be multiple pressures per tyre choice to find the optimum, same goes for road surfaces. Then there is human error to consider (e.g. you can easily be off by a few seconds through hand timing and the starting procedure). Ideally, each configuration should be tested many times to obtain statistically relevant data. This is why tyres are often tested on drums. It is much easier to isolate the actual effect of the tyre. So, overall this is mostly for entertainment purposes

Those bikes moved to huge profile downtubes, bottom bracket areas, and big profile deep seat posts (sometimes integrated) for improved aerodynamics. They were aero, stiff, heavy and harsh... They would beat you up with a 23mm or even 25mm tires. No wonder Trek came up with the IsoSpeed decoupler around that time to isolate the rider's ass from that tank, and everyone moved to bigger tires, which was also enabled by disk brakes. If you look at the newer bikes, while the downtube and BB area has stayed huge for stiffness, the seat tubes, seat stays and seat posts have become a lot thinner to not be as stiff... Seat post have moved back from big deep profile to 27.2mm or even D-shape so they would be a lot more flexible...

I think there are a couple ways to think about "faster". A 30-40 mile ride on in town w/ bumps, rough roads, over course of couple hours if you are more comfortable, less fatigue, in the end it seems you would carry a higher speed over longer distance. This vs just looking at watts/speed over shorter track. Just a thought...

All depends on rider weight. A 60kg rider won't need more than 23's at 60psi. A 90kg rider might need 28's at 80psi. Also remember it's not just about the tyre width but tyre weight also. There might be 50-100g difference between 23mm and 28mm tyres and as it's peripheral weight on a rotating wheel it makes a big difference unless on a completely flat road at a constant speed.

I did the club ride on my cross bike last year with 32 tyres on, it was hard as hell, they did not roll, was hanging on all day long. I swapped out to 28's and it was way better. Probably because the 32s we gravel kings and are a bit sticky for road riding.

20s front, 23s rear. Nice. Thank you .

@tomneufeld6477 Год назад

It would have been interesting to see what kind of results you got if you had expanded the test after the first round of results and added ~5-10lbs pressure to one of the larger sets of tires to see how they felt and/or were as fast as the smaller tires at recommended pressure.

@FRamirez1A 3 года назад

Funny: in the Enve website, for 21mm internal, 28mm tires and 165lb, the recommended pressure is about 66psi. Per zipp, for 23mm internal and 28mm tires, 75psi??? Would you share your weight? Thanks.

28 mm are the best. I have two bikes, one with 23 mm and one with 28 mm. The comfort you get with the 28 mm is just phenomenal, although we have quite good roads here in the Netherlands (compared to Belgium, UK, etc.)

HA! If you think having to pump up tires every single ride is a pain, try having to glue tires onto the rims, like we had to (NO race grade clincher tires whatsoever way back then!)when I first started racing in 1970. We also had to pump up said tubulars every ride as well, at least if we were using the higher grade, latex tubed variety (think; Clement Campionato Del Mundo Setas), even for training. ;)

I wonder how much of a difference clincher vs tubeless vs tubular would make in this test. I've heard tubulars still hold their profile better under load, especially when cornering, which is one reason why pros still generally prefer them. That and they tend to be the lightest combo.

Road conditions are rough on part of my routes and comfort and jarring are a consideration for sure. If I had perfect roads I'd stick with the 25's F & R as really quite happy with them. Nothing to complain about except the roads.

Riding aluminium track bike with 25mm front tire on 16 bladed spoke wheel, carbon fork. The rest of the frame is so rigid the 28mm back tire is a welcome addition. Got some aero like the bottles behind the seatpost. Still not ready for the rotational weight not mattering concept. If it didn't we'd all ride solid steel wheels.

@overcookit1433 2 года назад

Whatever tire manufacturers recommend as the best tire for me, I will stay with my NOS Supersonics (the ones that really had the size that was printed on the sidewall) with 20mm in front on a Mavic Cosmic Carbone SSC and 23mm in rear on either a HED Trispoke or a HED 3D-discwheel (a trispoke with closed holes), as long as I can catch those. Thanks to Josh Portners video "Your tires are lying to you", I (132 lb/60kg with 5.8ft/1,77m, riding a TT bike) reduced the pressure down from 131 psi/9 bar in front and 116 in rear in steps of nearly 4 psi to 102 psi/ 7 bar in front and 87 psi/6 bar on the rear tire, which feels smooth, and seems the best possible compromise between aerodynamics and rolling resistance. @GCN Tech: Have you tested what the size of the 25mm tire is on both a 13C and a 15C rim, as the tire size seems to refer to 19C-rims?

@brankododig1585 3 года назад

For races, spirited rides, and even long distances, running Corsa Speed tubeless at 23mm, my wheels are 25-ish mm external. On bad roads I just drop the pressure to 95 psi and it's really a comfortable setup, 105 psi on really good roads. Running GP5000 TL in 25mm for training on a spare wheelset, the Corsa Speeds are really delicate in comparison.

@jeremysart 2 года назад

When I bough my last road bike in 2016, the standard was 25mm @ 120psi.. just got a 2022 Domane SL6 and it came with 32mm with a max psi of 70. I was a bit surprised.

@steveb0503 2 года назад

Alright, I run 38c tires (700c diameter) on my gravel bike @ 79 lbs of pressure (because I ride mostly road) and have stem and seat-post suspension to compensate for the harder ride (aluminum frame). The tires are Specialized Pathfinders and even though they are are pumped tight, they handle pretty well on the moderate off-road riding that I do. Gotta say, I love this setup on the tarmac and am pretty satisfied with it on the trails too. I understand that this sort of set-up flies in the face of pretty much EVERYTHING I've ever heard about what is recommended - but it works for me...

@AJFixie 3 года назад

@g.fortin3228 3 года назад

@@AJFixie just be sure to give it a chance.. dial in your PSI for your body weight on the tires and thin tubes. Too low a PSI and it will be slower for sure. The extra durability and comfort of the larger tires is worth a small tradeoff too. (edited/corrected!) 25fr/28rear might be a another good option too.

@@HShango I should have mentioned that my daily ride is an (now) old aluminium frame road bike with a mix of componentry. It used to be all Tiagra, but I cobbled together a mix of parts to upgrade it over the years. My weekend ride is the carbon frame, on which I find myself suddenly going faster and feeling as light as a feather. LOL. I also started riding when tyres 19mm-20mm pumped to as hard as f##k was the norm. The curmudgeon in me is not entirely convinced of the wider-faster concept, but the scientist in me is ever curious and willing to experiment. There are constant clashes between my two personalities. Makes for entertaining internal dialogue. Ah ha ha! I might end up with 23mm-F/25mm-R on the carbon frame. I will also try tubeless as soon as I can afford the rims, on my current wages. I use the older bike as my daily ride to work and other errands. That way, if anything happens, I won't go ballistic. ;-)

@fritzel7858 2 года назад

I think it depends on different factors to find the right tires! I work as a courier. I've ridden 25mm for years. As I don't race or generally compete, I switched to 28mm rear about 3 years ago due to bad road conditions and cobblestones here! Which brought a slight improvement in comfort! I now ride 28 mm at the front and even 32 mm at the rear (max. tire clearance of my bike). The comfort is much better now and I'm definitely faster on our bumpy roads, of course slower on the -few- new, smooth roads! I think there's also a slight training benefit from running wider tires! Because of the higher watt output that you have to produce to drive the same speeds as on narrower tires! Even if you probably don't notice it in a race and on 25 mm!

@fritzel7858 2 года назад

Speaking of training benefits! I use my working hours as training intervals! During my work I carry a huge square "suitcase" on my back, which acts like a brake parachute, and at the same time I wear relatively loose clothing! I try to drive at my typical average speed of about 30-35 km/h! And in between I try to reach my top speed again and again! If I then ride without a backpack and with good cycling clothing in my free time, it feels as if I have a constant tailwind, even when there is a headwind! Maybe you should try it and make a video about it... and since I ride a track bike fixed with 49/15, Ollie spontaneously comes to mind as the perfect guinea pig! And before anyone gets upset about fixed gear here; Of course I drive with front brakes!
