Glad this came up. What I've always done is to use the factory recommended pressures as a suggested baseline, watch tire wear, and adjust. For me, it just so happens that 35 front and 31 back are the magic numbers on the BFG KO's that I'm running. Uh huh, asymmetric tire pressures for handling and tread wear reasons. When I haul a load of rock or whatever, the rears go up to 55-60. For best gas mileage in normal use, always run the highest pressure possible without causing excessive center tread wear.
