What must be checked to determine if a trailer will fail inspection regarding wheels?

To determine if a trailer will fail inspection regarding wheels, the inspection must focus on the condition of the wheel bolts, nuts, studs, or lugs. These components are critical for securing the wheels to the trailer and ensuring safe operation. If any of these parts are loose or damaged, they can pose a significant safety hazard by potentially allowing the wheel to detach while the vehicle is in motion.

A thorough inspection would include checking for any signs of wear, deformation, or corrosion on these parts. Ensuring that they are properly tightened to the manufacturer's specifications is essential for maintaining the integrity of the trailer’s wheels. This aspect of the inspection is vital for preventing accidents that could occur due to wheel failure on the road.
