I took a walk around the parking lot at work and eyeballed some of the chrome/aluminum rims. The Compass has them all beat! Subaru, Audi, a Dodge Truck and a Ford Truck came in not too far behind at maybe .200". I did have to look at the others a bit more closely because their sidewalls bulged quit a bit more and it just wasn't as obvious.
So far, I've had mine in 107 degree heat in Tucson (hate to think what the pavement temp was!) and tire pressure was up to about 44 psi going across the desert and it's been down to 22 degrees here at home. I filled up the tires before I left for Tucson to 35 and I haven't had to change that since. I had them rotated at 6K and all was fine. 8000 miles on mine so far.
