I am going to change the tires on the retarded rims that came on my Fuji Ace. The rims take a 700x26 tire which are near to impossible to find. What I want to know is if I can put a 700x25 tire on instead. I think I should be able to because the tubes I think go for 25 and 26 tires. I would just like to know from some people that probably know better than me.
