tire pressure/wear observations...

I think I'm running more tire pressure than necessary, at least for daily driving conditions. I just rotated the tires last weekend after ignoring them for about 5k miles, and since I'm running more negative camber than stock (settings are -0.8 deg camber front, -1.1 deg camber in the rear), I was expecting some inside tire wear. To my surprise, there was no noticeable inside tire wear, but there was significant middle tire wear which is indicative of too high a pressure for the weight of the car. I've only been running between 36-39 psi in the front and 32-35 psi in the rear. I guess that's more than necessary for daily driving that consists of just driving around town and highway driving. Tires are 225/45-17's mounted on 7.5" wide rims.

To keep the circumference the same, or the distance from the top of the wheel to the ground, it takes that much difference in pressure. I will be watching how mine wear.
