There are several angles to check and adjust on both the front and the rear wheels:

is the angle at which wheels are tilted in or out in relation to the top of the tyre. Provides direction control stability when travelling in a straight line.

is the angle between an imaginary line perpendicular to the centre line of the vehicle and a line through the wheels.

is the angle at which the leading edge of a pair of wheels points towards (“toe-in”) or away from (“toe-out”) each other.
