During a pre-trip inspection, what should be checked regarding wheel rims?

Ensuring that there are no cracks in the wheel rims and that they are securely attached is crucial for vehicle safety and operational integrity. Cracks can compromise the structural integrity of the rim, which can lead to a failure during operation, causing tire blowouts or accidents. Additionally, wheel rims must be securely attached to prevent them from loosening or detaching while the vehicle is in motion, which could result in loss of control.

While checking paint quality, chrome plating, or looking for spare rims may seem relevant, they do not directly impact the safety and functionality of the vehicle in the same critical way. Therefore, the focus during a pre-trip inspection should be on the condition and attachment of the wheel rims to ensure safe driving.
