Final answer:
For a pretrip inspection, wheels and rims should be free from damage, properly inflated, and have lug nuts tightened as per the manufacturer's guidelines to ensure vehicle safety and performance.
Step-by-step explanation:
During a pretrip inspection, it is essential to ensure that the wheels and rims are in good condition for the safety and efficiency of the vehicle. They should indeed be free from cracks or damage, properly inflated, and have the lug nuts tightened according to the manufacturer's specifications. It is because a wheel rim, while not very useful on its own, becomes fundamental to vehicle performance when paired with a tire. Together, they facilitate a safe and comfortable ride.
