Question Tire Pressures

We recently got a 2013 GL450 with the larger appearance package rims. What tire pressures do you run in the winter and summer? Thanks..

Check inside the fuel filler door for the MB recommended pressures.

I have my guys fill to 38 PSI - and drive feel after one week can be decreased or increased by 2 PSI to change "feel".

I had a dealer recommend 44 psi for the rear and 36 for the front for better tire wear.
