The 20p Pledge

The 20p pledge is a simple commitment to check the tread depth of your tyres using a 20p coin, to make sure they are safe and legal. It’s quick, it’s easy, and it could just help to save a life.



Using a 20 pence piece you can quickly and easily check whetheryour tyre tread depths are safe and legal. This keeps you and your passengers safe on the roads.

Simply insert a 20p coin into your tyre's main tread grooves to see if the outer rim of the coin is covered by the tread. Repeat this in the main grooves and at several points around its circumference. If you can see the rim of the coin when it is inserted at any point, your tyre may be illegal and should be checked by a tyre specialist.



Your tyres' condition is critical for acceleration, braking, steering and cornering and as the driver, you are responsible for making sure tyres are legal and roadworthy.
Failure to comply with the leagl minimum standards can result in fines of up to £2500 and 3 penalty points - per each illegal tyre. UK law requries car tyres to have a minimum of 1.6mm of tread across the central three quarters of the tyre around its entire circumference.
