Tyre pressure can affect your car’s handling, turning, braking and fuel efficiency. A tyre at the wrong pressure will wear out faster and might put your safety at risk.
It’s important to do this, because tyres lose pressure all the time.
Even in ideal conditions they lose about 0.69 bar or 1 pound per square inch (psi) per month – and that’s a figure that rises with the temperature.
So check your tyre pressure at least once a month, and while you’re at it have a good look at your treads.
If you don’t know what the recommended pressure is, you can find it in your owner’s manual or on the sidewall of your tyre.
