How does a control arm affect tire wear and alignment?

A control arm plays a significant role in determining tire wear and alignment in a vehicle. Here's how it affects them: Tire Wear: The control arm helps to maintain proper tire contact with the road surface. If the control arm is worn, damaged, or out of alignment, the tire may not be positioned correctly, leading to uneven tire wear. This can manifest as excessive wear on the inner or outer edges of the tire, known as camber wear, or as uneven wear across the tire tread, known as feathering or cupping. Alignment: C ontrol arms are an integral part of a vehicle's suspension system, which includes components responsible for wheel alignment. The control arm's position and alignment affect the camber, caster, and toe settings of the wheels. Improper control arm alignment can result in misalignment of the wheels, leading to uneven tire wear and compromised handling. Camber: Control arms influence the camber angle, which is the vertical tilt of the wheels when viewed from the fr...
