What is the minimum legal tread depth on a tyre for most vehicles?

The minimum legal tread depth on a tyre for most vehicles is 1.6 millimeters. This regulation is in place to ensure that tyres maintain adequate grip and control, especially in wet conditions. A tread depth of 1.6 millimeters allows for sufficient water displacement, which helps reduce the risk of aquaplaning and enhances overall vehicle stability.

If the tread depth falls below this minimum, tyres may not perform effectively, leading to longer stopping distances and a higher likelihood of losing control on slippery surfaces. This standard helps promote safety on the roads for all drivers. It is important to regularly check tyre tread depth to ensure compliance with this law and maintain safe driving conditions.
