Tire Pressures
Just got an S line with 20" rims, what are the tire pressure you guys are running for best ride/wear. I found the manual recommends 35psi.
Thank You

The max load pressures are listed on the door sticker at 44psi front, 49psi rear.
Normal load pressures are listed in the manual at 35psi front and 35psi rear.
I like the tires firmer and crisper and they wear longer with less rollover and edge wear at higher pressures. I run 42 psi front and rear unless heavily loaded or towing. Then I use the max load pressures. Tire wear is very good at these pressures. I get about 35000 miles from a set of Continental DWS. Wear is perfectly even across the tread. Hope that helps!

Also check the tire sidewalls, each brand, treadwidth and aspect ratio will have a different Pmax. The narrower, taller 18" Pirelli's I have on the 3.6 have a lower Pmax than the wider, shorter 19" Pirelli's I have on the 4.2. Same model of tire, just a different width and aspect ratio. The 3.6 I run around 40, the 4.2 I run around 42-43. I ditched the 3.6's factory 20's (sitting in storage), too harsh for the steel suspension.
