FMCSR 393.75(f) — Weight Exceeds Tire Load Limit

Yes—most of the time. Across our inspection records, 91.2% of 393.75(f) citations result in an out-of-service order. This is nearly three times the all-FMCSR average OOS rate of 31.4%, making this one of the most enforcement-heavy violations in the vehicle maintenance category. If an inspector cites you, expect your truck to be placed OOS until the overweight tire condition is corrected.

It's significantly more serious than most peer violations. While codes like inoperable lamps (393.9(a)) trigger OOS in only 15.4% of cases, and lighting defects (393.11) in just 1.8%, the data in our database shows 393.75(f) sits at 91.2% OOS. The only comparable enforcement intensity in the maintenance category comes from general inspection/repair violations (396.3(a)(1) at 45.3%), making weight-limit overages a top-tier safety concern for roadside enforcement.

No—this is a rare citation. Across 13 million inspections in our database, 393.75(f) accounts for only 125 all-time citations, ranking it #1361 out of 3,036 FMCSR codes. In the last 12 months, there was just 1 citation, and none in the last 90 days. This suggests either excellent compliance or limited roadside detection, but when it is cited, enforcement is swift and severe.

1. Do not move your truck—an OOS order is almost certain (91.2% of cases).
2. Contact your carrier or dispatcher immediately; they need to arrange tire replacement or load redistribution.
3. Document the tire placard limits and current load with photos; this may help during dispute review.
4. Request the inspection report and violation details in writing.
5. Have your tires re-rated or load shifted, then request re-inspection for OOS release.
6. Keep all repair receipts and communications for any future CSA review.

You may be able to dispute it if the inspector's measurement or calculation was incorrect. Weight and tire-load violations are technical findings—if the inspector did not properly weigh the axle, misidentified the tire rating, or miscalculated the load distribution, you have grounds to challenge the citation through the DataQs RDR (Roadside Deferral Review) process. Gather your truck's tire certification, load manifests, and scale tickets from the time of citation, then submit a detailed rebuttal within the filing window. Success depends on documentary evidence, not opinion.

U S N 1 TRANS LLC (USDOT 4039695) has the highest count at 8 citations all-time, followed by MAGNOLIA TRUCKING LLC and AAJM TRANSPORT CORP, each with 5. Across our inspection records, these carriers show patterns of tire-load management issues. If you work for a smaller or owner-operator outfit, citation risk is lower statistically, but the OOS rate (91.2%) applies equally across all operations.

Very urgent. Because 91.2% of citations result in an OOS order, you cannot legally operate until the violation is corrected. The data in our database shows almost no citations in the last 90 days, suggesting inspectors may be focused on other codes, but when they do catch weight-limit overages, they enforce it immediately. Do not attempt to operate on the road; arrange repair or load adjustment as your first priority.

Freightliners (FRHT) lead with 3 citations across our 13 million inspection records, followed by Peterbilt trailers (PTRB) and brazier models (BRAZ) with 2 each. Single citations appear across Dodge, Hyundai, Kenworth, Peterbilt, and other makes. Weight-limit violations are not brand-specific; they reflect operational load-management practices rather than equipment design, so any truck is at equal risk if overloaded regardless of manufacturer.
