Tyres MUST be correctly inflated to the vehicle manufacturer’s specification for the load being carried. Always refer to the vehicle’s handbook or data. Look in either the drivers or front passenger door pillar to see if there is a label with the correct pressures.
Check tyre pressures weekly. Do this before your journey, when tyres are cold. Warm or hot tyres may give a misleading reading.
Your brakes and steering will be adversely affected by under-inflated or over-inflated tyres. Excessive or uneven tyre wear may be caused by faults in the braking or suspension systems, or wheels which are out of alignment. Have these faults corrected as soon as possible.
