What is the minimum tire tread depth for a heavy goods vehicle?

The minimum tire tread depth for a heavy goods vehicle (HGV) is typically 1.6 millimeters (mm) in many regions, including the European Union and the UK. However, for optimal safety and performance, it is often recommended to replace tires when tread depth reaches 3 mm. Regularly checking tire depth is crucial for maintaining grip and preventing skidding, especially in adverse weather conditions. Always consult local regulations, as requirements may vary by jurisdiction.
