The tilted steering axis has another important effect on suspension geometry. Since the wheel rotates about a tilted axis, the wheel gains camber as it is turned. (ozebiz.com.au)

This pendulum type tool has 3 zones marked out on the bottom foot. Each zone, or the area in each zone, represents the allowable, or designed, amount of camber angle of a wheel in different positions. (2cvtools.com)

However, the effect of the strong camber on the wheel and the softer tyre is to give negative results, as the outer part of the tyre becomes deformed, and turns with a smaller rotation radius then the inner part, with the consequent increased wear on the outer strip of tread, (wheels in motion)
