What is the minimum tire tread depth mandated for commercial vehicles in BC?

The minimum tire tread depth mandated for commercial vehicles in British Columbia is 1.5 mm for the majority of the tire surface. This requirement is in place to ensure adequate traction, particularly in wet and slippery conditions, thus promoting safety on the road. Maintaining the correct tread depth is crucial as it affects a vehicle's braking distance, handling, and overall stability. Insufficient tread depth can lead to a loss of grip, increasing the risk of accidents, especially for larger commercial vehicles that carry heavier loads.

While other depths might seem appealing, they do not meet the legal standards set in the province for optimal safety. A depth of 1.0 mm or 2.5 mm does not provide the necessary performance, particularly in adverse weather conditions. The requirement of 1.5 mm balances safety and performance, ensuring that tires can effectively channel water away and maintain traction during critical driving situations.
