Air Pressure: what should I know?
- Check the air pressure of all four tyres monthly, including the spare.
- Check your tyre pressure before making a long trip.
How to check tyre pressure?
- Press the pressure gauge into the valve stem on your tyre.
- The gauge will “pop” out or if a round gauge type will show a number that corresponds to the internal pressure in the psi number.
- The hissing sound is air escaping the tyre. Press firmly on the air pressure gauge on the valve until the hissing stops.
- Compare the measured psi to the recommended psi. Usually recommended tyre pressures are located in log books or on the door pillar when you open your door.
- 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.
How do I know the recommended pressure for my tyres?
- In the vehicle owner’s manual (should be in the glovebox).
- On a sticker on the driver’s door or the fuel tank door.
Regarding pressure gauges
- Sometimes pressure gauges in a service station do not read properly. If you want to make sure, buy a quality tyre pressure gauge and use that.
Getting it right is important
- Under-inflated or over-inflated tyres can wear down your tyres 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.
