1: Measure the tire pressure when the tires are cold 2: Drive the car aggressively until the tires are warm. 3: Get out of the car and immediately measure the pressure. If the original (cold) pressure was correct, the new pressure will be 10% higher. If it is more than 10% higher, the original pressure was too low. If less than 10% higher, it was too high. – Uncle Duke, software designer, Fairfax, VA
