Tyres & The UK Law


When to Change a Tyre

If your car doesn't handle or grip the road as well as usual in wet weather or it takes longer to stop when you apply the brakes, this could be a sign that your tyres need changing. Because your tyres wear down gradually it can be difficult to identify these changes so we recommend that you have your tyres checked regularly.

Advice & Guidance on Tyre Tread and UK Tyre Law

UK Tyre Law : Tyre tread and the Law

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.

If you can see these bars your tyres are about to become illegal and unsafe. However, for optimum safety, most manufacturers recommend that your tyres are changed at 3mm. 

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. Whilst these markings are an indicator, always check the tread depth using a tread depth gauge and check your tyres regularly for bulges or wear.

Tyre Valves

The tyre valve is often the most neglected and overlooked component within the wheel and tyre assembly, yet 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. Even a poorly sealed valve can cause fairly constant under inflation of the tyre which will reduce the life of your tyre by up to 25%. As it is impossible to replace the valve without removing the tyre casing from the wheel.
