What is the legal minimum tread depth for car tyres?

Whilst the legal minimum required tread depth for a tyre is 1.6mm, we highly recommend checking your tyres tread depth frequently once it goes below 4mm as it could be indicative of additional problems such as wheel alignment, misaligned sterring or poorly inflated tyres (either over or under-inflated). 

Many vehicle manufacturers recommend replacing your tyres at 3mm. At the legal minimum of 1.6mm, it takes an extra two car lengths (approximately 8 metres) to stop at 50mph when braking in wet weather compared to 3mm.

Meeting the legal required minimum is paramount for drivers, with those who fail to comply facing a potential fine of up to £2,500 and 3 driving licence pentalty points per illegal tyre. Having all four of your tyres below the legal minimum can mean losing your driving licence outright.

Be sure to check your vehicle owner's manual for tyre fitment details when looking to replace any tyres failing to meet the tread depth requirements.
