Answer
2/32 inch is the minimum allowable tread depth required in every major groove on non-steer (drive and trailer) tires.
Federal commercial motor vehicle safety regulations require a minimum tread depth of 2/32 inch in every major groove on all non-steer tires (drive, trailer, and dolly axles). Steering axle tires require a minimum of 4/32 inch.
