What is the minimum legal tread depth?

Published 13 July 2016 in

The current law for the tread depth for cars, vans and LCV is to have a minimum depth of 1.6mm across the central three-quarters of the tyre and around the entire circumference.

It is recommended to increase the safety of the car to replace the tyres before the 1.6mm limit is reached. Many vehicle manufactures’ suggest replacing the tyres when they reach 3mm.

For any vehicles exceeding 3.5 tonnes the current law states that the tread should be a minimum of 1mm across the central three-quarters of the tyre and around the entire circumference.

Motorcycles over 50cc the minimum tread is 1mm across three-quarters of the width of the tread pattern and a visible tread on the remaining quarter. Motorcycles up to 50cc are required to have all grooves of the original tyre pattern clearly visible.
