For commercial vehicle operators in New Jersey, New York, and Pennsylvania, tire violations are among the most common causes of roadside out-of-service orders. A single non-compliant tire can ground your truck on the spot — costing you the load, the day, and potentially triggering a fleet audit. Here's what the Federal Motor Carrier Safety Administration (FMCSA) requires, and what NJ and NY inspectors actually look for.
The Governing Regulation: 49 CFR Part 393.75
All commercial motor vehicles operating in interstate commerce — and most intrastate commercial vehicles in NJ, NY, and PA — must comply with 49 CFR Part 393.75, which governs tire equipment standards. This regulation is enforced during roadside Level I inspections, weigh station checks, and terminal audits.
New Jersey, New York, and Pennsylvania all participate in the Commercial Vehicle Safety Alliance (CVSA) inspection program, which uses the same out-of-service criteria as federal DOT inspections. An inspector at the Bloomfield weigh station on I-78 or the Suffern truck inspection point on I-87 uses the same standard.
Key DOT Tire Violations & Penalties
| Violation | CFR Citation | Consequence |
|---|---|---|
| Steer tire tread depth below 4/32" | 49 CFR 393.75(a)(1) | Immediate out-of-service order |
| Drive/trailer tread depth below 2/32" | 49 CFR 393.75(a)(2) | Immediate out-of-service order |
| Tire with visible cord or belt | 49 CFR 393.75(b) | Out-of-service + civil penalty |
| Tire with sidewall bulge or audible leak | 49 CFR 393.75(c) | Out-of-service order |
| Regrooved tire on steer axle (except approved) | 49 CFR 393.75(f) | Civil penalty up to $16,000 |
| Tire load/speed rating insufficient for vehicle | 49 CFR 393.75(d) | Civil penalty |
Tread Depth Requirements in Detail
The most commonly cited tire violations involve tread depth. The FMCSA has different minimums for different axle positions:
These are the legal minimums, not recommended replacement points. Most tire manufacturers recommend replacing steer tires at 6/32" and drive tires at 4/32" for optimal safety and performance — well above the DOT floor.
Pre-Trip Inspection Requirements
Under 49 CFR 392.7, commercial drivers must perform a pre-trip inspection before operating a vehicle. The tire inspection portion must include:
- Visual inspection of all tires for obvious damage, bulges, or foreign objects
- Checking tire inflation — underinflation is the leading cause of DOT tire violations
- Inspecting lug nuts and wheel fasteners for tightness
- Verifying no tires are visibly flat or showing sidewall damage
- Checking valve stems and caps are present and undamaged
Driver Vehicle Inspection Reports (DVIRs) must be completed at the end of each day and must note any tire defects found. If a defect that affects safety is noted, the vehicle cannot be operated until repaired.
Common Inspection Points in NJ, NY & PA
Commercial vehicles operating in the Northeast are subject to inspection at multiple enforcement points. Common locations where tire violations are discovered include:
- NJ Turnpike weigh stations (Deepwater, Cranbury, Ramsey)

- Goethals Bridge and George Washington Bridge commercial vehicle lanes
- I-95 / I-287 commercial inspection areas in NJ and NY
- Delaware Memorial Bridge commercial inspection station
- I-78 Bloomfield weigh station
- Pennsylvania Turnpike commercial vehicle inspection areas
