Why Tires Lose Pressure

Why Tires Lose Pressure? Tires can loose one PSI (Pound Per Square) per month under normal conditions. Additionally tires can lose 1 psi for every 10 degrees F temperature drop. Make sure you check your tire pressure every month. For accuracy, check your air pressure with a good Digital Tire Gauge when tires are cold. Driving heats up tires and makes the reading incorrect.

To check your tire pressure remove tire valve cap. Place the end of the tire gauge over valve stem. Press the tire gauge straight and firmly until the digital gauge indicates a pressure reading. If needed, add air and recheck pressure with the tire gauge. Replace valve cap.
