Can you run road tires on a 29er wheel?
I have a couple sets of Stan's ZTR 355 29er wheels that I use for Cyclocross. Those rims have a maximum PSI that always kept me from running road tires on them during the off-season.
Then I started thinking...that can't be right. So I did some math to calculate the pressure on the rim based on tire size. Below is a list of tire sizes and inflation pressure, all put the same amount of
tension pressure on the rim:
So yes, you can run road tires on a 29er rim. Obviously, you wouldn't run 700x21 or probably even 700x23 tires on fat rims. IMO 25c or 28c tires should be fine.
