Good answers to tire pressure questions

[patticake]

Talking about "problems" with air pressure differences, think about an airplane.
When I was in the Air Force, we had to check the air pressure(on B-52's) before every flight. They had to be exact. As a kid, I never thought much about it, until my crew chief told me why(other than safety). He said, basically, think about the changes the tire goes through from the ground to high altitude and back, plus, when upon landing, they are not rotating at all, until they touch the runway.
Gives a new respect to what a tire goes through in it's life.
