TIP OF THE MONTH
Did you know?
There is no such thing as a completely ‘air-tight’ tyre. Loss of air pressure in a tyre causes it to sag and in turn cast a bigger ‘footprint’ on the road surface, which leads to greater rolling resistance. This means more energy is required from your car’s engine to propel your vehicle to a given speed and maintain it at that speed.
To overcome this resistance, the car’s engine needs to work harder to move at the same speed so it’ll use more fuel. While fuel economy rally drivers over-inflate their car tyres, we wouldn’t recommend it for day-to-day driving as over-inflated tyres can cause a loss of steering control, a less comfortable ride and reduce stopping distances.
To know the correct tyre pressure for your car, either refer to your car owner’s manual or the label at the side of the driver’s door, or fuel filler flap.
The decal should look something like the one shown on the left.
Some drivers look to all sorts of little gadgets and fuel additives to increase their cars’ performance, but the most efficient upgrade that you can get for your car doesn’t even cost any money. The solution is literally found in the air.
The right amount of air in your car’s tyres makes a big difference to performance, fuel economy, and safety. Unfortunately, tyre air pressure tends to be one of the most overlooked aspects of a car.
Driving and cornering at high speeds on under-inflated tyres is also dangerous. The tyre sidewalls will squirm and flex, resulting in unpredictable handling. Under extreme circumstances, a tyre might even pop off the wheel.
You will usually find the recommended tyre pressures for your car printed on a label affixed to the front door frame or under the fuel filler cover. The range of acceptable pressures is also printed on every tyre sidewall. As rubber is porous, there is no tyre that will hold its air forever. Checking your tyre pressures whenever you refuel will go a long way in improving your car’s handling and fuel economy.
