Tires are the only parts of a car which are in contact with the road. Therefore, safety in acceleration, braking, steering, and cornering all depend on a relatively small area of road contact.

Recommended tire inflation pressures for your vehicle can be found in the vehicle handbook and/or the driver’s door post. In the absence of either of these, consult the tire manufacturer.

Correct pressures are related to loads, speeds and vehicle handling and are vital for maximum safety, braking, grip and good tire life. Prolonged under-inflation causes excessive flexing, deterioration of the casing, and rapid wear of the tread shoulders. The vehicle will also consume more fuel.

Over-inflation results in an uncomfortable ride, a reduced area of contact with the road, and accelerated wear on the tread center, as well as making the tire more susceptible to impact damage. Inflation pressure should be checked at least once a month and only when the tire is cold, since there is an increase in pressure when the tire has warmed up after being run. This change in pressure is accounted for when manufacturers set recommended tire pressures.
A reliable and accurate pressure gauge should be used.

Top Tips for checking tire pressures correctly

1. Check your tire pressure at least once a month.

2. Tire pressure should be checked against the vehicle manufacturer’s recommended level. This can be found in the vehicle handbook and on a plate which is often located inside the fuel filler flap or on the driver’s door sill.

3. Check the pressure when tires are cold (i.e. when you have traveled less than two miles).

4. If you are carrying a full load of passengers or luggage or will be towing a trailer or caravan, tire pressures should be increased in line with the vehicle manufacturer’s recommendations. Details can be found in the handbook or the driver’s door post.

5. Ensure a reliable and accurate pressure gauge is used.

6. Check the pressure in all four tires; remember to check the spare tire as well.

7. While checking pressures, give the rest of the tire a visual inspection. Remove any stones and other objects embedded in the tread. Look out for any bulges, lumps or cuts.

8. If you are unsure on any aspect of tire pressure or tire condition, take your vehicle to an approved tire dealer and speak to the experts.
