Checking your Tyre Tred: The Twenty Pence Test

You may have noticed that your vehicle tyres have lots of grooves all over them; these are called “Tred” and are actually designed to improve your vehicles grip on the road in wet conditions and avoid Aquaplaning (when your vehicles tyres have insufficient tred to clear water from the road surface).

The legal UK minimum tred depth is 1.6mm to ensure you are able to control your vehicle safely in wet conditions.

If your tyres fail to meet the legal limit, you could face hefty fines and penalty point on your license. It is important to check you tyre tred regularly we know a simple and effective way you can do so at home.

The Twenty Pence Test.

Make sure you vehicle is parked on a flat surface and turn your steering wheel in the opposite direction of the side you are going to test (if you are testing the tred on the right hand side of your vehicle, turn the steering wheel fully left as to gain easy access to your tyre tred).

Ensuring you are in safe surroundings, simply place a twenty pence coin into the tred grooves and focus on the outer band of the twenty pence piece.

If the outer band is obscured or disappears, then you are within the legal limit. However, if the outer band is visible, you may be within an illegal and unsafe limit and you should have your tyres checked by a professional immediately.
