what is the legal tyre tread depth

The legal minimum tread depth for car tyres in the UK is 1.6mm across the central three-quarters of the tyre, according to law. The tread must meet this minimum requirement across its complete circumference. If a tyre is worn below this limit, it is not only a safety hazard but also puts the driver at risk of incurring a fine of £2,500 and three penalty points per tyre. Ideally, car tyres should be checked every month to ensure that they are well above the legal minimum. It is advisable to have your tyre replaced once it reaches 2mm, however, most experts recommend replacing your tyres when they have a minimum of 3mm tread depth.
