Contrary to popular belief, tyre pressures is not determined by the type of tyre or its size but upon your vehicle’s load and driving application i.e. speed. To find out what your car’s tyre pressure should be, consult the manufacturers tyre placard usually found inside the driver’s door sill, glove box, fuel filler cap or under the bonnet.
The placard should also displays the manufacturers recommended tyre sizes.
Tyre pressures should be checked when the tyre is ‘cold’, as the tyre warms up the pressure increases. Try to ensure that pressure gauge is an accurate one,
Take the “cold” reading and check them against the recommended tyre pressures from your placard.
Heavy loads or towing puts an extra strain on your tyres. So if your vehicle is fully loaded with passengers and luggage, the general rule is to add 4psi.
Believe it or not, checking your tyre pressure can have a big impact on our environment. 20% of the fuel consumed by your vehicle can be attributed to rolling resistance from your tyres. An under-inflated tyre creates more rolling resistance and therefore more fuel consumption. By keeping your tyres inflated to their proper levels, you can help maximise your car’s fuel economy and minimise its impact on our environment. Most tyre manufacturers have started developing different rubber compounds with the aim of reducing rolling resistance. The key is to do this without sacrificing grip levels and consequently safety. Michelin has been at the forefront of this technology since its first ‘Energy’ tyres in 1992 and now with the “Total Performance’ range incorporating the fuel savings with very high performance levels.
