Check your Tyre Pressures Once a Month or before long journeys.

Tyres can actually be quite under inflated without looking "flat". So you should check the tyre pressures regularly, particularly before a long journey. The right tyre pressure is one factor in the safety and longevity of your tyres.

Ideally, check pressures when the tyres are cold; this means that they have not been used in the last 2 hours, or they have covered less than 2 miles at low speeds. Any tyre not in this "cold" condition is considered to be "hot".

If the tyres are "hot" when they are checked:

Add 4 to 5 psi (0.3 bar) to the pressures recommended by the vehicle manufacturer.

Never reduce the pressure of a "hot" tyre, even if the pressure is above the recommended level.

Re-check the pressures when the tyres are cold.

In cases of unusual pressure loss, have the internal and external condition of the tyre, the condition of the wheel and the valve checked by a tyre specialist.

Inflation with nitrogen does not dispense with the need for regular tyre pressure maintenance as specified above.

Recommended tyre inflation pressures for your vehicle can normally be found in the vehicle handbook or on a label fixed on the vehicle, for example on the door frame or the fuel filler cap. Use the pressures relating to your tyre sizes and vehicle load/speed conditions.
