Mileage is better, and the tires are wearing fine (over 55K so far). The Trans Am has a stiff ride anyway, but I'm sure that my high inflation isn't helping. It definitely corners better at the high pressure. You should watch your tires for center wear if you do this, but I doubt you'll see any. In fact, you'll probably see edge wear if you don't do this (and leave the tires at glove compartment spec. (low)). Car manufacturers seem to be more concerned with getting a softer ride than with tire wear and possibly reduced cornering. Though I thought they were supposed to be concerned with mileage.... You'll know your tires are too high if things are shaking loose from the car when you go over bumps! Good Luck. -- Neal Macklin (408) 737-5214 ...{hplabs,ihnp4}!amdahl!nzm10 [There are no opinions expressed in this article].
