splain me this. and tell me if i've got a problem with my reasoning.
1. 25mm is testing better than 23mm in most rolling resistance tests.
2. in the limited amount of testing i've seen, isn't 28mm outrolling 25mm?
3. wider tires are also likely to be more comfortable (lower pressures).
4. almost 6 in 10 are choosing 23mm or thinner.
yes, there are aerodynamics to consider as well. is this your argument? or is there something wrong with my chain of reasoning above?
One thing to consider is that wide-rim clinchers increase the effective tire size. For example, a 25mm-wide (external) / 21mm-wide (internal) Hed Plus rim makes a tire labeled 23mm inflate to about 25-26mm actual. So - is the poll asking about labeled
size, or measured size when inflated?
And, frame fit is an issue. I have a custom tri bike that can fit 30mm tires. But it's an extremely rare bird. It was outstanding when I used to live in Michigan, with their abysmal road quality. I never understood how people rode 23mm tires at 100psi or more in that state. Newer tri bikes are slowly accepting wider tires, but it's often capped at about 25mm actual/inflated size.
