The Law requires that your vehicle is fitted with the correct type and size of tyre for the vehicle that you are driving, and for the purpose for which it is used. There are also laws in place to govern all aspects of your tyres condition, the most important of these is the tread depth. The legal minimum depth of the tread on your tyre is 1.6 millimeters across the central 3/4 of the tread going around the complete circumference of your tyre.
Tyre safety checks are extremely important and should be done on a regular basis. The penalty for having illegal tyres on your vehicle is currently up to a £2,500 fine and 3 penalty points per tyre.
