Why stop at 25? Why not slap on 40mm+ tyres on every race bike and claim it's faster? Surely you're not the first person to claim this.
Give me a break
Operator, I'm sorry your mother never loved you, but I don't blame her.
From
Sheldon Brown's article on tyres:
"The short answer to this question is that, yes, a wider tyre of similar construction will have lower rolling resistance than a narrower one at the same pressure."
Perhaps there is more to a tire than rolling resitance. Perhaps a wider tire is heavier. Perhaps a wider tire increases aerodynamic resistance. I guess I misspoke. The tire is not necesarily faster, but may have lower rolling resistance.
Perhaps I should have said that "if a wider tire and a narrower tire are inflated to the same pressure, the wider tire will have slightly less rolling resistance!" Oh, wait. That is what I said.
