Which of the following would cause a wheel to fail inspection?

A wheel failing inspection due to loose bolts on the wheel assembly is a clear safety concern. The wheel assembly must be securely attached to the vehicle to ensure that the wheel can withstand the stresses of driving, such as acceleration, braking, and turning. Loose bolts can lead to wheel detachment while the vehicle is in motion, which poses a significant risk to the driver and others on the road. Therefore, having secure and properly tightened bolts is crucial for maintaining the reliability and safety of the vehicle.

In contrast, using standard rims on a modified vehicle can sometimes be permissible if they are appropriate for the modifications made. Having a matching set of tires is normally a good practice and does not inherently cause inspection failures. Properly functioning bearings are essential for vehicle operation and would not lead to a failure either. All of these points highlight the critical role that secure wheel assembly plays in passenger safety and vehicle performance.
