Measuring Tire Pressure
Doing a little car maintenance and tire pressure is on the things to do list. A simple question that may not be that simple, when do you measure the pressure. Should the tires be warm or should the tires be cold?

I agree that cold is the correct way to measure pressure. Just wanted to share an experence I had last Wed. when checking my truck tires before a 1000 mi trip. It was 50 deg. outside and very sunny. I checked the tires on the north side ( shady) of the truck which had set out all night and they were the recommended 35 psi which is what I keep them at. Went to the south side ( sunny) and they were at 38psi for both front and back. I left them alone assuming that the direct sun light on them had increased the pressure by the 3 psi.
