What is the minimum tread depth required for commercial vehicle tires in Alberta?

The minimum tread depth required for commercial vehicle tires in Alberta is 1.6 mm. This standard is established to ensure adequate traction, handling, and safety on the road, particularly in adverse weather conditions. Tires with sufficient tread depth are essential for maintaining proper contact with the road surface, which helps in preventing hydroplaning and improving braking performance.

Having a tread depth of at least 1.6 mm allows the tires to effectively channel water away and enhance grip, critical aspects for commercial vehicles that often carry heavy loads and operate at higher speeds. Ensuring that tires meet this minimum requirement is vital for both safety and compliance with provincial regulations. Regularly checking tire tread depth is an important maintenance task for commercial drivers to uphold safety standards.
