Just fitted new 20" wheels on my car and want to know what pressure everyone is running on their tires with aftermarket wheels. Tire sizes are as follows: Front: 255/30/20 and Rear: 295/25/20. Many thanks.

Wow....11" in the rear? That must look awesome!!!! Would love to see some pictures.
I run 35 psi on all four corners. What did your wheel/tire dealer recommend? You really have to watch them though. 20's have such a low aspect ratio (short sidewall) it's hard to tell if they are low on air or not. Hopefully that tire pressure system is working!!!

hi everyone! just ordered similar size front: 255/30/20 and Rear: 295/25/20 new wheels/tyres.
most people seem to have 35PSI all round, but on standard wheels the pressures are always DIFFERENT for rears and fronts, should i keep the pressure on front and rears different on aftermarket wheels/tyres too?

There should be maximum tire pressures on the tires that you buy for the wheels, so that can give you a better idea. 35PSI seems to be the normal pressure for 5 series though.
