Tires, 23's vs. 25's, brands?

[maillotpois]

In Bicycle Quarterly a study was done on tires. the smaller tires were not the faster ones, the bigger ones were!

I remember skimming this article at SK's. As V said there was more to it, I just don't recall the specifics. But if 25s truly were "faster" than 23s, then the pros would be using them and they are not. So they simply can't be "faster".

I use Michelin Pro Race 2s. 23. I can get up to 2000 miles, but have been known to forget to change then til the bead is showing through. Ooops!
