UK Tyre Law

When it comes to the attributes of a car tyre, there are a few areas, which are essential in UK law. Principally the tramp depth, speed, and load indexes, as well as the quality or durability of the tyre. Here, we will analyse the various UK tyre laws and legal requirements that you, as the driver, need to be informed.

Tread depth

There should be no areas where the tread depth goes below 1.6 mm as it is the least depth which is required. This is of paramount importance - and the fact that 1.6 mm is a legal requirement in many countries . Tyre manufacturer’s often give recommendations to indicate the level of wear and tear on your tyre.

UK Tyre Law: Tyre tread and the Legal Requirements

The law requires car tyres to have a minimum tread depth of 1.6mm in a continuous band around the central three-quarters of the tyre. To help you judge how much tread you have on your car tyres, manufacturers often mould tread bars at roughly 1.6mm.

Many manufacturers now include a Tread Wear Indicator (TWI) within the grooves of the tyre tread which become more visible as the tyre wears down,and is recognizable by the driver.

Tyre Valves

The tyre valve is often the most neglected and overlooked component within the wheel and tyre. An efficient valve is important for the safe operation of the tyre. Wear on the valve seal, damaged screw threads, dirt and grit in the valve itself can lead to failure of the tyre at speed.
