What 393.205A means in plain language
When you're cited for 393.205A, an inspector found a problem with one or more wheels or rims on your truck. The defect could be a crack in the rim, a break in the wheel structure, or a missing component—like a lug nut, trim ring, or hub cap. The regulation requires that every wheel and rim on a commercial motor vehicle be in good working condition and free of defects that could affect safety or cause the wheel to fail while you're moving.
This is a structural issue, not a minor cosmetic problem. A cracked rim can collapse under load. A broken wheel component can separate during operation. Missing parts can expose the brake components or wheel hardware to debris and moisture. Even if your truck feels fine on the road, the defect puts both you and other drivers at risk.
What our enforcement data actually shows
Across our 13 million+ inspection records, 393.205A citations are relatively targeted. We've recorded 2,259 all-time citations for this code, with 1,327 issued in the last 12 months and 281 in the last 90 days. That places 393.205A at rank #513 out of 3,036 FMCSR codes by citation frequency—not the most common violation, but far from rare.
The critical number: 71.9% of vehicles cited for 393.205A were placed out of service at the roadside. That's more than double the all-FMCSR average out-of-service rate of 31.4%. When an inspector cites you for a defective wheel or rim, there's a strong likelihood they'll also pull your truck from service immediately. Our data shows this enforcement pattern is consistent: inspectors treat wheel and rim defects as safety-critical issues that cannot be ignored or deferred.
In the last 90 days alone, we recorded 281 citations nationwide. That steady enforcement volume signals that wheel and rim defects remain a visible focus in roadside compliance checks.
Who gets cited most
Our inspection records show enforcement is concentrated in a few high-traffic regions. Texas leads with 438 citations over the last 180 days (66.9% placed out of service), followed by New Mexico with 119 citations (84.9% out-of-service rate) and North Carolina with 31 citations (74.2% out-of-service rate).
The variation in OOS rates across these states is material: New Mexico enforces this violation more aggressively than Texas—84.9% versus 66.9%. If you operate in the Southwest or Southeast, the likelihood of a 393.205A inspection and an immediate roadside out-of-service order is higher.
Our data shows large carriers such as FEDERAL EXPRESS CORPORATION with 8 all-time citations and fleets like SWIFT TRANSPORTATION CO OF ARIZONA LLC with 5 citations also appear in our enforcement records. This is not an indication of negligence by any carrier—it reflects the volume of miles these fleets operate and the frequency of inspections they encounter.
How severe is this compared to similar codes
Within the Vehicle Maintenance category, 393.205A sits in a unique enforcement position. The most frequently cited peer code is 393.9(a)—Inoperable required lamps—with 660,737 all-time citations but only a 15.4% out-of-service rate. Wheel and rim defects are cited far less often, but when they are, inspectors respond with an out-of-service order 71.9% of the time.
Another comparison: 393.78 (Windshield condition defective) has accumulated 157,894 citations but only a 0.3% out-of-service rate. And 393.11 (Lighting devices/reflectors) shows 179,734 citations with just 1.8% out-of-service. By contrast, 396.3(a)(1)—the general inspection and maintenance code—carries a 45.3% out-of-service rate across 236,919 citations. 393.205A's 71.9% OOS rate is among the highest in its category, signaling that wheel and rim defects are treated as imminent-hazard violations.
How to avoid it
Our co-occurrence data reveals that wheel and rim defects often appear alongside brake system violations. In the last 90 days, 393.205A appeared in 33 shared inspections with 393.45B2UV (Brake tubing/hoses inadequate) and 32 shared inspections with 393.47E (Slack adjuster defective). This pattern suggests that when wheels and rims degrade, brake-adjacent components are often compromised too. The takeaway: a thorough brake system inspection will catch many wheel-related issues before an officer does.
Our data also shows that vehicles from the top cited makes—Freightliner (FRHT: 783 citations), Kenworth (KW: 399 citations), and Utility (UTIL: 368 citations)—appear frequently in 393.205A enforcement. This doesn't mean these makes are defective; it reflects their prevalence in the fleet. But if you drive one of these models, apply extra scrutiny to wheels and rims during pre-trip.
Action steps:
- Before every trip, walk around your entire truck. Get down and look at each wheel and rim at eye level and from below. Look for visible cracks, breaks, or missing lug nuts, trim rings, and hub caps. Don't skip wheels you think "look fine."
- Check for wobble. Spin each wheel by hand (or have it spun during a pit stop) and watch for lateral movement or grinding. A rim that's bent inward or outward is a defect.
- Inspect after rough roads or load shifts. If you've driven over rough terrain, hit a pothole hard, or shifted a heavy load, do an immediate wheel inspection. Damage to rims is often acute, not gradual.
- Don't defer maintenance. If you notice a cracked rim or missing component during a pre-trip, don't plan to "fix it at the next terminal." Stop and address it or get the truck serviced before you move. Our data shows inspectors will cite you, and the out-of-service rate is too high to gamble.
- Verify brake components during wheel service. When you have wheels serviced or inspected, ask the mechanic to check brake tubing, hoses, and slack adjusters at the same time. The co-occurrence pattern in our data suggests these systems age together.
