Final answer:
The question is about the inspection of the liner area of a tire in the field of automotive engineering, which can only be done once the tire is removed from the wheel.
Step-by-step explanation:
The question refers to the inspection of the liner area of a tire, which is specifically related to the field of automotive engineering. The process mentioned requires that the tire be removed from the wheel. This reveals that the inspection of the liner area is part of tire maintenance and is essential for ensuring the safety and longevity of the tire. It is assumed that the liner refers to the inner lining that holds the air within the tire.
