-
Ambient temperature affects the tire pressure (about 1 psi (7 kPa) for every 12°F (7°C) change). If colder temperatures are anticipated, it is permissible to increase cold tire inflation pressure by up to 3 psi (20 kPa) over the specification. If extreme temperature changes are expected, be sure to check and adjust tire pressure accordingly.
-
Tire inflation pressure decreases with higher elevation, and increases with lower elevation (about 2.4 psi (10 kPa) for every mile (or kilometer) elevation change). Be sure to check and adjust tire pressure accordingly when driving through changing elevations.
-
Do not exceed the maximum inflation pressure, as found on the sidewall of the tire(s).
When replacing tires, ALWAYS use the same size, type, brand, construction and tread pattern supplied with the vehicle. If not, it can damage the related parts or make it work irregularly.
