Tyre Safety – Tread Depths and Tyre Pressure

Tyre Safety

Legal Tread Depths

In the UK tyres must have a minimum depth of 1.6mm across the central three quarters of the breadth of tread. This minimum tread must exist around the entire circumference of the tyre.

As a rough guide 1 millimetre of tyre tread lasts between 1,000 and 4,000 miles depending on -

    • The quality of the tyre (the rubber compound)
    • Correct tyre inflation
    • Road quality
    • Weather conditions
    • Driving style
    • Tread pattern depth will also affect your braking distance on a wet road by up to 50%
