What is the minimum legal tyre tread depth?

Answer: B — 1.6mm across central 3/4 of tyre all the way around

The minimum legal tyre tread depth in the UK is 1.6mm across the central three-quarters of the tyre all the way around. This standard is set to ensure that tyres have sufficient grip on the road under various conditions, particularly in wet weather. Adequate tread depth is crucial for maintaining traction, preventing aquaplaning, and ensuring effective braking. When the tread depth falls below this legal requirement, it can significantly compromise vehicle safety and handling, increasing the risk of accidents. The requirement applies to all vehicles using public roads, and failing to comply can result in penalties, including fines and points on your driving record. Regularly checking tyre tread depth and replacing tyres that are worn out beyond this limit is key to safe driving.
