What is wheel camber?
Camber is the inward or outward tilt of the tire/wheel assembly. This angle is measured from a true vertical line, i.e. perpendicular to the ground. A tire/wheel assembly that is tilted outward at the top is considered to have Positive camber. For a zero setting, the tire/wheel assembly is in the exact vertical position or perpendicular to the ground. To rephrase, if the top of the tire/wheel assembly is tilted inward towards the engine, it has a negative camber. If the top of the tire/wheel assembly is tilted outward from the engine, the camber is positive.
