Factory Specs on Tire Pressure?

32-35 is a good baseline. I run 35 in all my tires and get 40-50,000 miles out of a set with proper alignment and occasional rotation. I don't rotate as often as recommended. With a bad alignment and frequent rotations, you can ruin a whole set of tires in a hurry. If you leave them alone and watch the wear, you will know what the problem is and can correct it. tmm
