What are all you guys running for tire pressures. I have found over the course of more than a year that my Kumhos would roll perfect at about 31-32 psi cold both front and rear. I might take a pound or two out here and there depending on the course. I see a lot of guys running like 45 psi up front. I have never had to go that high, so what is the deal. Do I just drive that gracefully (while still slaughtering the comp) or am I missing something? And yes my tires have worn down even.
