The ideal steering angle for perfect rolling of all wheels when cornering varies with the speed of the car and the tightness of the turn, owing to suspension movement and deflection of the tires.

Since the steering arms point slightly inwards in relation to the direction taken by the car, the angle of the inside wheel when cornering will be slightly greater than that of the outside wheel.
