I have not seem more than 1 psi increase in pressure from cold to hot. They seem to run cold all the time. 50 psi is 50 psi for me. Tires have steel belts around them to hold them in shape. I have never seen a tire wear out in the center from being set a few lbs over pressure. My tires are wearing flat....just like they are supposed to.

EDIT: I borrowed a friend's flat bed trailer a few months ago to haul the tractor. I checked the tires before leaving and my air gauge exploded in my hand!!!! It was an 80 lb gauge too. It had well over 150 lbs in the tires and they were wearing flat. He hauls VERY heavy loads on occasion, and so he leaves them "fully inflated". These tires are half worn down as they have seen many miles, but they are wearing flat.
