What is the minimum legal tread depth for tyres on cars?

The minimum legal tread depth for tyres on cars is 1.6 mm. This standard is set to ensure that vehicles have sufficient grip on the road, particularly in wet conditions. Tread depths below this measurement can significantly increase the risk of aquaplaning, reduce braking effectiveness, and decrease overall vehicle control. Ensuring that tyres are within the legal tread depth not only promotes safety for the driver and passengers but also for other road users. Following this regulation helps maintain adequate performance and safety levels while driving, reflecting the importance of proper tyre maintenance.
