What is the minimum tread depth required on front wheels?

The minimum tread depth required on front wheels is essential for maintaining safe traction and handling, especially in adverse weather conditions. A tread depth of 4/32 inch is the legal standard and recommended minimum for front tires on commercial vehicles. This depth ensures that the tires can effectively channel water and provide the necessary grip needed during inclement weather, such as rain or snow, significantly reducing the risk of hydroplaning.

When the tread wears down below this minimum threshold, the tires may not perform effectively, leading to longer stopping distances, decreased handling precision, and an increased likelihood of accidents. Hence, keeping a sufficient tread depth is critical not only for compliance with safety regulations but also for overall road safety.
