Which component is primarily affected by improper camber adjustment?

Improper camber adjustment primarily affects tire wear. Camber refers to the tilt of the wheel relative to the vertical axis when viewed from the front. If the camber is too positive or too negative, it can cause uneven tire contact with the road surface, leading to increased tread wear on one side of the tire. This uneven wear not only shortens the lifespan of the tires but can also compromise vehicle safety and handling.

Tire wear is critical because it directly impacts traction, stability, and the overall driving experience. If the camber angle is adjusted correctly, the tires will wear evenly, resulting in a more predictable and safer vehicle behavior during driving. This makes tire wear a crucial factor influenced by proper camber alignment.
