Tyre pressure can affect your car’s handling, turning, braking and fuel efficiency. A tire at the wrong pressure will wear out faster and might put your safety at risk.
Check them regularly
It’s important to do this, because tires lose pressure all the time.
Even in ideal conditions they lose about 0.069 bar or 1 pound per square inch (psi) per month – and that’s a figure that rises with the temperature.
So check your tire 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 tire.
