Even though I'm worried about the oversize issue on wide rims, I don't think the thread with is an issue at all.
Corsa speed are the crit king tires, and they have exactly the same tread width

In the local crit here, not many people use Corsa Speed. The road is averaged with a bit stone and sand from the side.
You can hardly blame the grip of a tire when you slide out on a sandy corner. Even Corsa Speed wouldn't help there.alanyu wrote:In the local crit here, not many people use Corsa Speed. The road is averaged with a bit stone and sand from the side.
What tires are used on your local crit scene?
I've used old Pro one, GP5k TL, kenda Valkyrie TL, and Pzero Race TLR, in which GP5k TL is the only one brought me trouble. I don't corner through the real sandy/gravel part.Maddie wrote: ↑Sun Jun 19, 2022 5:42 pmYou can hardly blame the grip of a tire when you slide out on a sandy corner.

That’s silly of you. The narrow tread cap is made much much worse on the Power Cup because it’s a 29mm tire. Corsa Speeds are probably around 26mm on my SES 5.6. I wouldn’t use Corsa Speeds on 21mm internal rims either.
If you’re having trouble visualizing this. Imagine a 300mm wide tire with a tread cap as narrow as a Corsa Speed. If you lean even the slightest amount, you’re riding bare casing/sidewall.
Take a look at BRR. It's nearly the same as a % of case width, not in absolute terms.TobinHatesYou wrote: ↑Sun Jun 19, 2022 7:11 pmThat’s silly of you.

My 28mm Power Cup TL measured 31.0mm mounted on 25mm internal hookless rims. Took them out for 70 miles yesterday, rolling hills and twisties. The tread wear looks to stay just inside the tread cap. These could take a few more degrees of lean angle. Measured them again this morning at 31.4mm after a weekend of riding.
The tires felt very fast and comfortable during the ride.
Do these tires have a rotation direction indicator hidden somewhere? I gave up looking for it and just mounted them. I suppose since they are completely slick, the direction does not matter?

No direction on slick tires (as long as they don't have aero artifacts, like the GP5k).allrandomletters wrote: ↑Tue Jun 21, 2022 3:02 pmMy 28mm Power Cup TL measured 31.0mm mounted on 25mm internal hookless rims.

Even knoby tires can be mounted both directions. For gravel Rene Herse for exemple they you say that recommended (arrow of the tread pointing forward) favors speed and wet-grip on asphalt (better water flow). But backwards mounting favors grip in muddy conditions.

The tread wear stays in the center because if you lean too much the bike will naturally get back up
I have the same feedback as you but its a bummer i cant corner as hard as i used to one my old GP5K
Which wheel will likely face more lean angle? Front or back?
I guess it's the back, right? because front wheel countersteer out of the corner?
I'm still waiting to try mixed brand combo.
GP5000 front for smaller size and aero shaped tread pattern.
Michelin rear because the size and aero stripe doesn't matter as much.
But I'm not sure if that make sense, tread width wise.

Michelin front/ Conti back however doesn't sound like the right way of doing it. At least not the fastest way

Tires behave differently when inflated. A 25mm Corsa Speed G2.0 measures something like 27.5mm on the RSL 37s. My Power Cups measure 29.5mm. That 2mm difference in diameter equates to roughly 6mm in circumference. With a vulcanized tire, I would bet the portion of the casing under the tread stretches less than the thinner sidewalls also.
