What is the law for tread depth limits within the UK?
A. For more information, go to UK tyre law. However, to briefly outline it for you the law states that cars and light trailers (including caravans) up to 3500kgs gross vehicle weight and/or eight seated passenger vehicles (including the driver), must have a minimum of 1.6mm of tread depth in a continuous band across the central three quarters of the tread width, throughout the entire circumference of the tyre.
