Difficulty: MediumTires, Wheels, and Rims Inspection

During a pre-trip inspection, a commercial driver discovers a hairline crack on a steel wheel rim that has been reinforced with a certified bead weld; under commercial motor vehicle safety standards, this wheel assembly is legally compliant for highway operation.

Answer: Answer

Answer

False (welding repairs on commercial vehicle wheels and rims are strictly prohibited and violate safety standards)
Federal CDL safety regulations state that wheels and rims cannot have welding repairs. Any cracked or damaged rim must be removed from service and replaced rather than welded.

Step-by-Step Solution

1
Evaluate the condition of the wheel rim described in the scenario.
The wheel rim has a crack that was repaired using a bead weld.
Pre-trip vehicle inspection procedures require drivers to inspect all wheels and rims for cracks, deformities, and unauthorized repairs.
2
Apply federal commercial vehicle safety standards regarding rim and wheel defects.
Welding repairs on wheels and rims are unsafe and illegal, placing the assembly in out-of-service condition.
Welding compromises the structural integrity of the metal, creating an unacceptable risk of wheel failure or tire blowout during highway operation.
