What is the minimum tread depth required for front commercial tires?

The minimum tread depth required for front commercial tires is established for safety and performance standards. For front tires, a tread depth of 4/32 inches is the legal minimum. This depth helps ensure adequate traction, especially in wet conditions, reducing the risk of hydroplaning and improving handling and braking performance.

When the tread is worn below this level, the effectiveness of the tire in providing grip significantly diminishes, directly impacting vehicle safety. It is crucial for commercial drivers to maintain proper tire tread depth, not only for compliance with regulations but also to ensure the safety of themselves and others on the road.
