Question

Quizplus · Accepted Answer

Technician A is incorrect because even tires of the same nominal diameter can have different rolling radii due to variations in tire construction and wear. Technician B's method is not accurate for determining rolling radius, as it does not account for the tire's deformation under load and other factors affecting the actual rolling radius in use.
