A colder ambient local temperature will reduce pressure within the tyre. An effect is to decrease sidewall height and to increase tyre shoulder wear with the potential for tyre failure.
Vehicle dynamics could also be adversely affected.
Tyre pressures can be adjusted to compensate before the start of the journey. Alternatively, tyre pressures can be adjusted when the area of lower ambient temperature is reached.
In this situation, the vehicle must be left in the ambient local temperature for at least one hour before tyre pressure is adjusted.
To compensate for colder ambient temperatures, tyre pressures should be increased by 0.14 bar (2 psi, 14 kPa) for each 10°C (20°F) decrease.
Note: Ensure that correct tyre pressures are maintained when moving to areas of differing ambient temperature.
