The UK Law & Tyres.
UK law requires that your vehicle is fitted with the correct type and size of tyre for your vehicle type.
This means having the correct tyres and 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.
We recommend that you replace your tyres before the legal limit is reached ensuring your vehicle is safe. Vehicle manufacturers recommend replacing at 3 millimetres. At 1.6 millimetres in wet weather it can take up to 8 metres more to stop at 50MPH.
The current penalty for illegal tyres is 3 points and up to £2,500 in fines. So a regular check is recommended. The law also states that you should not fit tyres of different construction types on opposite sides of the same axle. You should check to make sure both tyres are either radial or cross-ply.
