The number on the tire is still only the max for the tire...the factory psi may not be exact for an aftermarket set, but it's going to be close to what should be used. best thing to do would be to get your vehicle's actual weight and contact the manufacturer of the tire for the optimal pressure. Most people won't go to that trouble though. In any case, DON'T run at max rated pressure...that's just asking for a blowout.
