Know the Tyre Law
The legal minimum tread depth for car tyres in the United Kingdom is 1.6mm across the central three quarters of the breadth of tread and round the entire circumference of the tyre.
Most car tyres have tread wear indicators, usually at least six small ribs across the bottom of the main tread grooves, and when the tread surface becomes level with these ribs the tyre is at the legal limit and must be replaced.
