Tyres and the Law
UK law requires that your vehicle is fitted with the correct type and size of tyre for the vehicle type you are driving and for the purpose it is being used.
This means fitting the right tyres and for safety ensuring that they are inflated to the manufacturer's recommended pressure.
The legal limit for minimum depth of the tread on your tyres is 1.6 millimetres, across the central ¾ of the tread around the complete circumference of the tyre.
For safety reasons it is recommended that you replace your tyres before the legal limit is reached. Many vehicle manufacturers recommend replacing at 3 millimetres. At 1.6 millimetres in wet weather it takes an extra two car lengths (8 metres) to stop at 50 mph than if your tread was 3 millimetres.
A regular check of your tyres can help you to avoid 3 penalty points and £2,500 in fines for having tyres worn beyond the legal minimum limit on your vehicle.
It is also a legal requirement to ensure that tyres of different construction types are not fitted to opposite sides of the same axle. The two main tyre types are radial and cross-ply, and these must not be mixed on the same axle.
Mixing brands and patterns of the same construction type is permissible depending on the vehicle type and manufacturers recommendation. Check your vehicle's handbook for tyre fitment details and options or ask your local Kwik Fit team for assistance.
