tire pressure
I'm curious if anything has been written or reported about recommended tire pressure after the vehicle has traveled several miles. Do auto manufacturers factor in distance traveled when they recommend a specific air pressure for tires?
I know that tire pressure should be checked when the tires are relatively cold (driven a mile is OK). I drove about 7 miles today and checked my air pressure. It was at the manufacturer's recommended pressure. So, am I to assume that they are actually underinflated and should have more air?
Do the tires heat up uniformly--i.e. can I check them at home when they're cold, then travel the 7 miles to fill them? Can I assume that if they are 4 lbs. under at home, they still need 4 lbs. when I get to the gas station? If I do that, then they will be overinflated. I don't see this being a tremendous problem now, but come summer when the air temp is 108, it will be.
BTW, I am a cheap-a$$ and this station is the closest with free air to us (and it's on the way to a place we regularly visit, so we're not going out of our way). Everyone else charges at least $0.50 and we usually have to pay $1 to get all tires filled correctly.
Thanks!
