How To Check your tyres tread depth

It is important to remember to check your tyre tread depths. 


The legal minimum tread depth for cars in the UK is 1.6mm. If you do not have enough tread on your tyres, they will not be able to achieve optimum performance in wet conditions.  At Protyre, we advise to consider replacing your tyres well before they reach the legal minimum.

The law states that drivers with tyres that fall short of the minimum legal tread depth risk being fined up to £2,500 and given three penalty points for EACH illegal tyre.

Checking your tread depth

Using a 20 pence piece you can easily check whether your tyre's tread depth is within the legal requirement. 

To check your tyres:
  • Insert a 20p coin into your tyre's main tread grooves to determine if the outer rim of the coin is covered by the tread
  • Repeat this action in the main grooves of your tyres but ensure this is done at several points around the tyre's circumference
  • If you can see the rim of the coin at any point, your tyre may be illegal and will need replacing as soon as possible
