Toe represents the angle derived from pointing the tires inward or outward from a top-down view. Different types of vehicles need different toe settings to allow for the way that wheels pull either towards each other or apart.
Correct toe is paramount to even tread wear and extended tire life. If the tires are incorrectly pointed inward or outward, they will scrub against the surface of the road and cause wear along the edges. Camber:
Camber angle is the measure in degrees of the difference between the wheels vertical alignment perpendicular to the surface. Maintaining the ideal camber angle throughout the suspension assures that the tire is operating at peak efficiency.
Camber settings will influence both the directional control and the tire wear. The camber has a lot to do with how well they grip the road especially when cornering. The more surface area between your tire and the road, the better the grip and the more stability you'll have.
