Yeah fixite7: I live in Florida and when the truck sets a week in 40 degree nights it's very lumpy until the tries warm up. Also I just looked at my owners manual and the factory says 40 PSI in the front and 55 PSI in the back. I just run 40 all the way around, I have no idea why my tire guy put 90 PSI in them. Kind of scary!
