Incorrect tyre pressure can result in tyre damage, increased fuel consumption and adversely affect the handling of the vehicle. Tyres that are not correctly inflated cause longer stopping distances, reduce stability for braking and cornering and increase your chance of a blow-out.
Incorrect pressures also reduce the life of your tyres by causing uneven wear, so need replacing sooner. Recent Studies found that 90% of all cars have incorrectly inflated tyres, which means that 9 out of 10 drivers are in danger. Tyre pressures should always be checked when cold and ideally every two weeks (including the spare wheel). Correct tyre pressures can be found in the owner’s handbook, on the driver’s door or on the fuel cap.
How to check your tyre pressure
Maintaining correct inflation pressure is essential and avoids premature or uneven wear. As tyres naturally lose pressure over time, you need to refill them regularly. Driving on the correct tyre pressure will extend the life of your tyre, improve vehicle safety and maintain fuel efficiency. Check your tyre pressure at least once a month, when your tyres are cold, and before long journeys. Follow our step-by-step advice on checking your pressures:
Find the correct pressures in your vehicle handbook or inside the driver’s door or fuel cap(this will be a figure in psi or bar).
The plastic cap on the air valve.
Press the tyre-pressure gauge against the valve and hold it down firmly. If you hear a hissing noise, you are letting air out. Press down harder.
Read the measurement on the gauge.
To add air, pump gauge until correct pressure is shown. To deflate, depress the tyre valve.
