CAMBER
What: Camber is the inward or outward tilt of the wheels, as seen from the front. Camber is positive when the top of the wheel tilts outward and negative when the top of the wheel tilts inward. Camber is zero when the wheel is perfectly vertical.
How: The camber angle is measured between the centerline of the wheel (as seen from the front) and a true vertical line, which intersects the centerline at the point of tire contact with the road.
The purpose of camber is to uniformly distribute vehicle load across the tire face to minimize tire wear. Excessive positive or negative camber, however, will increase tire wear dramatically on one side of the tread—the side toward which the top of the wheel is leaning.
Incorrect camber angles can also cause steering problems. Too much positive camber, for example, will cause the vehicle to pull in the direction that the wheel is leaning. Too much negative camber will cause the vehicle to pull in the opposite direction.
