Please forgive my ignorance on the following subject, but I am just getting started into a cycling life.
I tried to mount some new tires on a road bike rim last night and had all kinds of problems. I got the tire sized at a shop, and they assured me it was correct.
My question is, do you have to really stretch new tires when installing, I have changed hundreds of flats, but never a new installation.
I would really appreciate your patience and your help in solving my dilemma without having to have the shop do it.
