Camber angle refers to the angle between the tire's centerline and the vertical line when viewed from the front of the vehicle. Its positive or negative value affects the tire's contact patch and force application point with the ground, which in turn influences tire grip and wear. It also alters the distribution of vehicle weight on the axle, reducing abnormal bearing wear.
Additionally, the presence of camber angle can counteract the angular changes caused by suspension component deformation and play after vehicle load. The magnitude of the camber angle also affects the vehicle's direction of travel, so the camber angles of the left and right wheels must be equal to ensure straight-line stability and prevent uneven tire wear. When adjusting camber, toe angle must be considered. Increasing negative camber requires increasing toe-out, and increasing positive camber requires increasing toe-in.
