The latest supermarket fuel price war is good news for motorists who want to save money at the pumps, but did you know that you can also cut your petrol and diesel bill by making sure your tyres are properly inflated?
According to Michelin, tyres under-inflated by 15 psi (1 bar) have increased rolling resistance leading to around 6% greater fuel consumption. This is because lower tyre pressure increases the drag on a car, which means that the engine has to work harder and more fuel is used, making the vehicle less economical.
The correct pressures for your vehicle can normally be found in your owner’s manual. The information may also be marked on the driver’s door pillar or on the inside of the petrol flap. In most cases, two different sets of pressures are given:
• For ‘normal’ driving conditions
• For a loaded vehicle (with extra people or heavy items on board)
To check your tyre inflation pressures you will need a tyre pressure gauge or you can use the gauge on the inflation equipment found at most garages and petrol stations.
Tyre pressure must be checked when the tyres are cold, this means that you have driven less than two miles, otherwise you have to wait for about 10 minutes to let the tyres cool down.
