Track Width Difference

Track width difference is defined as the angle
between the joint line of the ground-contact point of
left wheels and that of the right wheels. It is positive
when distance between the centre of the rear wheels
is large than that of front wheels; and negative
otherwise. If the wheelbases are available from the
vehicle specifications, then the tread difference can
be also expressed by angle. See Fig. 1.7.
