Tyre guidance. The legal stuff
The legal limit for a tyre in the UK and Europe is 1.6mm across the central three-quarters of the tyre and around its complete circumference.
As a tyre wears, the distance it takes to stop your car increases significantly, especially when the tread gets below 3mm.
If your own safety doesn’t seem to bother you, maybe the risk of a £2,500 fine and three penalty points on your licence for a worn tyre will? That’s per tyre, too. If all four tyres are worn below the legal limit, you could potentially lose your licence and face a £10,000 fine.
