All tire pressures (including the spare) should be checked when the tires are cold. “Cold tires” means the vehicle has not been driven for at least three hours or has been driven for less than 1.6 km (1 mile).
Warm tires normally exceed recommended cold tire pressures by 28 to 41 kPa (4 to 6 psi). Do not release air from warm tires to adjust the pressure or the tires will be under-inflated. For recommended inflation pressure, refer to “Tire and Wheels” in chapter 8.
WARNING
Recommended pressures must be maintained for the best ride, vehicle handling, and minimum tire wear.
Over-inflation or under-inflation can reduce tire life, adversely affect vehicle handling, and lead to sudden tire failure that could result in loss of vehicle control resulting in an accident.
Severe under-inflation can lead to severe heat build-up, causing blowouts, tread separation and other tire failures that can result in the loss of vehicle control resulting in an accident. This risk is much higher on hot days and when driving for long periods at high speeds.
