1. 3. 1 Camber
Camber is the leaning of the wheel inwards or outwards from the vertical.
If the
road wheel leans outwards from the vertical, it has positive camber and when leaning
inwards from the vertical - negative camber, looking from the front or rear of the
vehicle. See Fig.1.1. Camber is measured in degrees.
Without camber, the wheels
will tilt to the inside at full load; increase the possibility of uneven tire worn. Hence, this
parameter can extend the life of tire and related axis.

1. 3. 2 Toe-in
The toe setting is the amount by which the front or rear wheels point inwards or
outwards at the front of the wheel in relation to each other (see Fig.1.2).
When the
wheels point inwards they are said to toe-in. Toe-in figures are given a positive value.
Conversely when the wheels point outwards they are toe-out and the figures are shown
as a negative value.
The purpose of correct toe is to ensure that the wheels run parallel when the vehicle is
driving. An incorrect toe setting may affect the stability and controllability of the
vehicle.
