Tire Pressure Max

I'm sure after this "hypermiling" trend becomes more well known, and a few 60 PSI tires blow violently causing mayhem on the freeways, the danger of overinflation will spark a few tire pressure studies focusing on overinflation.

99% true, but tires do increase pressure on their own as temps increase (you probably already knew that). I've heard that for every 10degree F increase, the tire pressure goes up 1 lb.
