Camber is an important wheel alignment angle because camber is both a tire wear angle and a directional control angle. Camber is the inward or outward tilt of the top of the tires when you view the tires from the front of the vehicle. The tire will have a zero camber if the center line of a tire is perfectly vertical. Positive (+) camber means the top of the wheel tilts outward (2). Negative (-) camber means the top of the wheel tilts inward (1). An excessive amount of positive camber will cause outside shoulder wear on the tires. Likewise, an excessive amount of negative camber will cause inside shoulder wear.

Excessive camber will result in tire wear. Additionally, excessive camber will cause the vehicle to pull or lead to the side with the most positive camber. The vehicle will pull to the side with the most positive camber if there is a difference in camber from one side of the vehicle to the other. To better understand the camber's effect on directional control, think of a tapered cone that will not roll in a straight line.

Camber is measured in degrees. The actual camber specification is the angle which provides the best tire wear and directional stability.

Camber adjustment is only available at the front wheels.
