– Check the pressure of all your tires monthly, including the spare. Even if you don’t see any damage, tires can lose up to 1 psi – pounds per square inch – every month. This can be accelerated by air leaks due to accidental puncture, leaks in the valve or valve cap, or by wheel malfunction.
– Check your tire pressure before making a long trip.
– For the best results, check your tire pressure when the tires are cool – before driving the car or if it has covered less than 3 KM at low speed.
– If the tire is hot, add 4-5 psi to the car manufacturer’s recommended pressure value or wait until it has cooled down, which is an average of three hours after parking the car.
How do I check my tire pressure?
1. Insert the pressure gauge into the valve stem on your tire.
2. The gauge will “pop” out and show a number that coresponds to the internal pressure in the psi number.
3. The hissing sound is air escaping the tire. It shouldn’t affect pressure substantially, unless you hold down the air-pressure gauge for too long.
4. Compare the measured psi to the recommended psi.
5. If the psi is above the recommended number, let air out until they match. If it’s below, add air until it reaches the proper number.
Where can I find the recommended pressure for my tires?
– In the vehicle owner’s manual.
– On a sticker on the driver’s door or the fuel tank door.
– Do not use the number on your tire’s sidewall, as this does not indicate the pressure needed in your tire.
Getting it right is important
– Under-inflated or over-inflated tires can wear down faster than expected, have reduced grip and can consume more fuel. It just takes a few minutes a month to help ensure your safety and the longevity of your tyres.
