The air pressure in your tyres affects your vehicle’s driving performance and impacts fuel efficiency as well as potential safety. Correct tyre inflation also extends the life of your tyres – poorly inflated tyres are prone to excessive and uneven wear.
All motorists are advised to check their tyre pressure at least once a month, and both prior to and following long journeys. You are also advised to inspect your tyre treads for uneven wear, which can be a symptom of over- or under-inflation.
Even under ideal driving conditions, tyres will typically lose pressure at a rate of about 0.069 bar or 1 pound per square inch (psi) per month, more so in warmer conditions.
If you’re not sure of the correct pressure for your tyres, check your vehicle owner’s manual or the tyre sidewall.
