The minimum tread depth for front tires on a commercial vehicle is 4/32". This standard is established because adequate tread depth is crucial for maintaining traction and handling, particularly in adverse weather conditions. Tread provides the necessary grip that allows the vehicle to maintain control, especially when navigating wet or slippery surfaces.

Having a sufficient tread depth reduces the risk of hydroplaning, improves braking distance, and enhances overall safety by ensuring that the tires can effectively channel water away from the contact surface. A tread depth of 4/32" is considered the minimum to ensure that these safety and performance features are maintained on the front tires, which bear a significant portion of the vehicle's weight and are responsible for steering and directional control.
