What is the minimum tread depth for the front tires of a commercial vehicle?

The minimum tread depth for the front tires of a commercial vehicle is 4/32 inch. This requirement is crucial for maintaining adequate traction and ensuring safe handling, especially in adverse weather conditions such as rain or snow. Tires with insufficient tread depth can significantly increase the risk of hydroplaning, reduce braking efficiency, and impair cornering stability.

For most full-sized passenger vehicles, a tread depth of 2/32 inch might still meet standard safety regulations; however, commercial vehicles, which often operate at higher weights and speeds, demand greater levels of safety. Consequently, the regulations are stricter for front tires, as they are responsible for steering and play a vital role in vehicle control.

In contrast, options suggesting lower tread depths, like 2/32 inch, would not provide adequate grip and could endanger both the driver and others on the road. Higher figures, such as 6/32 inch or 8/32 inch, exceed the minimum legal requirement but are not mandated by regulations, meaning drivers should ensure they meet at least 4/32 inch to be compliant and safe while on the road.
