you will notice that the inside tire has a higher camber change than the outer one - this is because the inner tire is turned at a larger angle than the outer one (Ackerman steering), resulting in more camber change for the inner wheel.

the main purpose of the camber change is to maintain the tire contact patch at an optimal level as the vehicle rolls when negotiating a curve, and as the tire sidewall flexes from the lateral forces.

another effect of positive caster is a self-centering characteristic, which contributes to high-speed stability.

however, it also makes the car prone to "tramlining", as the front tires encounter longitudinal ruts and grooves on the road, which becomes more pronounced with wide, low profile front tires.
