DOT and inspection guidance
Commercial Truck Tire Compliance
Understand the tire conditions that can create roadside inspection problems, including tread depth, exposed ply, flats, leaks, separation, load limits, retreads, and regrooved tires.
Federal compliance topics to review
- Steer tires generally require at least 4/32 inch tread depth in major grooves.
- Other commercial motor vehicle tires generally require at least 2/32 inch tread depth.
- Exposed ply or belt material, tread separation, sidewall separation, flats, and audible leaks are major inspection risks.
- Regrooved and retreaded tire rules vary by axle position and vehicle use; steer axle use deserves special caution.
- Load rating, inflation, axle weight, and tire condition should be reviewed together, not as separate checks.
