The legal minimum tyre tread depth

Ebony Barker • July 8, 2024

You should check your tyre tread depth at regular intervals to ensure your safety whilst out on the roads. Having worn tyres can increase the chance of being involved in an accident and you could be fined or face penalty points for driving a car with bald tyres. 


The legal minimum tyre tread depth for cars and light commercial vehicles is 1.6mm across the central three-quarters and around the entire circumference. Once this limit is reached, you must replace your tyres to ensure they remain legal. At CARS, we recommend a minimum of 3mm to maximise vehicle safety and performance at all times. 


When checking for tyre wear, you should look out for smooth patches of tyre tread and bulging or cracking in the tyre wall, amongst other factors. 


If you’re unsure whether your tyres are suitable, or just want general advice on vehicle maintenance, don’t hesitate to give CARS a call.
