FMCSR 393.67F-F: Tire Defects — Driver Q&A

No. Across our inspection records, 393.67F-F citations result in a 0.0% out-of-service rate—meaning your truck will not be placed out of service for this violation. Out of 50 all-time citations for this code, zero trucks were removed from service. This differs significantly from the 31.4% average OOS rate across all FMCSR codes, making this one of the least severe enforcement outcomes.

This violation carries a CSA severity weight of 6 points. Under the FMCSA CSA system, your total points accumulate over a 30-day rolling period and feed into your Unsafe Driving BASIC. A single citation for tire defects is relatively modest compared to high-severity violations, but repeated citations within 30 days will compound your score. If you've been cited multiple times recently, review your inspection records to see the cumulative impact.

Immediate steps:

1. Inspect your tires for fabric exposure, bumps, bulges, or cuts matching the citation details.
2. Check coupling and brake systems. Our inspection records show that 393.67F-F frequently co-occurs with 393.55D1-B (coupling defects) and 393.43B-BATV (brake relay valve issues)—get these inspected too.
3. Verify your windshield condition (393.78A-WS appears in 4 co-occurring inspections with this code).
4. Replace or repair defective tires before returning to service—do not dispute this on the roadside.
5. Document the repair with photos and receipts for your compliance file.

This citation is less serious than most vehicle maintenance violations by OOS outcome, but it signals a broader inspection issue. While 393.67F-F has a 0.0% OOS rate, peer codes in the same category show higher enforcement stakes: 396.3 (general maintenance) has a 45.3% OOS rate, and 393.9 (inoperable lamps) carries a 6.9% OOS rate. The fact that you were cited for tire defects often means inspectors found additional problems—our data shows 6 co-occurring driver language/documentation violations in the last 90 days alone.

Yes, you can file a DataQs challenge through FMCSA's Record Dispute Resolution process if you believe the citation is inaccurate or unfair. For equipment defects like tires, a successful challenge typically requires evidence that the tires did not actually have the defects described at the time of inspection—for example, photo evidence from an independent inspection showing the tire condition was acceptable. Document-based errors (missing inspection records, wrong vehicle identification) are also contestable. Your best success comes within 90 days of citation; gather photos and repair receipts immediately.

In the last 180 days, our inspection records show 24 citations for 393.67F-F in the US overall, with Arizona leading at 2 citations and Montana at 1 citation. This code ranks #1629 out of 3,036 FMCSR codes by citation volume, meaning tire defects citations are infrequent relative to other violations. If you were cited in the US, you're in a relatively low-citation environment for this particular defect.

Repair urgently—today if possible. Although your truck will not be placed out of service (0.0% OOS rate), the defect remains a safety violation and roadside inspectors may re-cite you if they observe the same tires on a subsequent inspection. Our 90-day trend shows 11 citations over the past quarter, with a spike of 13 citations in December 2025, indicating consistent enforcement activity. Do not operate the vehicle interstate until the tires are repaired and documented.

International trucks dominate our citation records with 17 all-time citations for 393.67F-F, followed by Freightliner at 8 citations.
