How Do I Check The Tread Depth Of My Tyres?

Struggling to find out if your tyres are safe to drive with? Make sure you meet the legal requirements with this how to video.


• First, make sure your handbrake’s on and the ignition’s off.

• Turn the steering to full lock for full view of the tyre.

• On the sidewall of the tyre, look for ‘TWI’ (Tread Wear Indicator).

• Above TWI, you’ll see little blocks. These are the Tread Wear Indicators.

• TOP TIP: The legal minimum tread depth is 1.6 mm. But for your safety, the depth should be no less than 3mm.

• If the tread is level with the Indicators, it’s at its legal minimum depth. Your tyres will need to be changed as soon as possible, you cannot carry on driving with smooth tyres.

• There’s another way to check the tread.

• The bevelled edge of a 20p coin is 3mm deep.

• If you can’t see that edge, the tread is good to go.

• Don’t forget to look in different places around the tyre because it might be the case of certain areas are more worn out than place you tried.
