Never drive your vehicle if the tire pressures are incorrect. Under-inflation causes excessive flexing and uneven tire wear. This can lead to sudden tire failure. Over-inflation causes harsh ride, uneven tire wear and poor handling.

Pressure checks should only be carried out when the tires are cold, and the vehicle has been stationary for more than three hours. A hot tire at or below recommended cold inflation pressure, is dangerously under-inflated.

Under-inflation also reduces fuel efficiency and tire tread life and may affect the vehicle’s handling and stopping ability.

If the vehicle has been parked in strong sunlight, or used in high ambient temperatures, do not reduce the tire pressures. Move the vehicle into the shade and allow the tires to cool before rechecking the pressures.
