I looked at the recommended tire pressure on the sticker inside the door panel on my 08 and couldn't believe it they recommend 35psi rear and 30psi front. Anyone ever heard of this??? The truck was delivered with 35 all around and that's what I've kept it at because it's always worked well for me on this and previous vehicles. The only thing I can think is that they're trying to enhance handling, but I gotta think 30 up front is going to wear out those tires in a hurry. It had the OEM Michelins.
