My car is E46 330ci and the tire has upgrade to size Front 255/35/18. Could anyone tell me how much tire pressure I need?

The suitable tire pressure depends on the weights of your car..and the loadIing. For E46 330ci ,I think 40psi is Okay.
However,if the tire is filled with N2, u may slightly enhance the tire pressure upto 45psi.
