Which of the following is involved in a tire alignment check?

A tire alignment check primarily involves measuring the angles of the wheels. This process ensures that the wheels are properly aligned with each other and with the vehicle's suspension system. Proper alignment is critical for optimal vehicle handling, tire wear, and overall safety. The angles measured typically include camber, caster, and toe, which are essential to maintain the vehicle's intended path and performance.

While measuring tire pressure, balancing wheel weights, and inspecting tread wear patterns are also important aspects of tire maintenance, they do not specifically pertain to the alignment check itself. Tire pressure affects fuel efficiency and tire lifespan, balancing ensures that the weight is evenly distributed to prevent vibrations, and inspecting tread wear can indicate alignment issues but is not part of the actual alignment measurement process. The core of a tire alignment check rests on the precise measurement of wheel angles to ensure alignment is within manufacturer specifications.
