What is the minimum tread depth required in every major groove of a tire that is not on the front of a commercial vehicle?

The minimum tread depth required in every major groove of a tire that is not on the front of a commercial vehicle is 2/32 of an inch. This standard is set to ensure that tires maintain adequate traction and handling in various driving conditions. Adequate tread depth is essential for the safe performance of a vehicle, especially when it comes to water drainage to prevent hydroplaning, as well as maintaining grip on the road surface for effective braking and control.

Tires with tread depths less than the minimum requirement can lead to decreased safety and increased risk of accidents due to impaired tire performance. Understanding these regulations is crucial for commercial drivers, as maintaining proper tire condition is a key aspect of vehicle safety and compliance with DOT regulations.
