: : We just figured out what the tire pressure should be on our 17" factory wheels (it's on the inside of the drivers door). Anyway, they were over-inflated from the dealer by at least 3 psi. I thought the ride was kind of rough. BE SURE TO CHECK THE TIRE PRESSURE FROM THE DEALER. They don't seem to know how to properly inflate the tires, particularly on the non-standard 17" wheels.
