Keeping your tyre pressure where it's supposed to be can cut down on your fuel bills and make your car safer to drive.
The Which? Car Survey 2021 has opened to the UK public. It's your chance to tell us about the car you drive, you don't need to be a member and you could potentially win £2,500 for taking part.
It's important that your tyre is making the correct amount of contact with the road - over or under-inflated tyres mean less grip on the tarmac.
Check your car manual to find the correct tyre pressure, and use our convertor tool if the measurements don't match the pump.
