Tire Pressure Gauges

Tire pressure is measured with a tire pressure gauge in pounds per square inch (psi) or kilopascals (kPa) and should be checked at least once a month. Recommended tire pressure is calculated according to the tire type, vehicle weight, and the desired ride. Maintaining the recommended tire pressure is critical to minimizing tire wear and optimizing handling stability. For every 10 degrees (F) the temperature drops, tire pressure drops by 1 psi (6.9 kPa). The inverse also occurs as temperature rises.
