I try to keep the rear at 25psi and the front at 29psi. I think it says recommended pressure is 45 or so, that is way too high, I also make it a point to take sharp corners slowly, so that I dont eat up the outsides on the front tires. A truck with 40" tall tires that weighs over 7000lbs in not really the kind of truck that you like to "throw""" into a corner or tool around a neighborhood at 60mph in either.
