Challenging 396.7A-LT through FMCSA DataQs

If this violation was written incorrectly, here are the angles trucking-safety managers use to contest it. Playbook: Tires.

Common ways to challenge this code

Tread measurement disputed
The tread depth measurement was taken at a worn point that is not representative, contrary to NHTSA/FMCSA measurement standards.
Evidence that wins
- ✓Independent tread gauge reading from same tire (multiple positions)
- ✓Photograph of the tire with a reference scale
Inflation context — recent stop or temperature
The under-inflation reading was taken immediately after a long-distance high-temperature run or before warm-up, not at the FMCSA standard measurement state.
Evidence that wins
- ✓Tire-pressure-monitoring system log (TPMS)
- ✓Service receipt showing inflation at start of trip

Common pitfalls — avoid these

⚠Inflation readings can't be challenged with a re-inflation done after the stop — must show original-state evidence
