D-Man said::lol: It said 75psi max pressure. I was only at 50 psi. I usually run 40 though but I need new batteries so I pumped up higher. What really sucks is that they keep discontinuing my tires. I had some Michelins that were really nice. They were 2.3 but actually measured 2.5". Great tire. Its gone! Now I buy these Kenda that are suppose to be 2.3 (58mm) and they are only 56mm. Maybe they will stretch. Probably should of got the 2.5.
