Quizplus · Accepted Answer

Technician A is correct because the bolt circle, or bolt pattern, indeed refers to the diameter of an imaginary circle that passes through the center of the wheel's lug holes, which is a crucial measurement for ensuring the wheel fits the vehicle properly. Technician B is also correct because lug nuts do come in different tapers (such as conical, ball, and flat) to match the seating style of the wheel lug holes, ensuring a proper fit and secure mounting of the wheel to the vehicle.
