I was told that a 26" mountain bike tire only fits a 25" rim. Is that true?
i haven't measured my rims, but if you order a rim that says it's a 26" rim, then a 26" tire will fit it. the only issue might be if you tried to put a wide tire (say 2.35" or 2.5") on a rim with a skinny interior width (19mm).
