The track (toe-in = illustration "a", toe-out = illustration "b") is the position
of the wheel level to the driving direction.

When driving, the tyres are pushed apart at the front because of the
rolling friction and are therefore no longer exactly parallel to the driving
direction. To balance this out, the wheels can be adjusted so that they
point slightly inwards at the front when the vehicle is not moving. This
toe-in improves the cornering of the tyre and thus results in a more
direct control of the steering.

If a softer steering response is desired, the toe-out can be adjusted
accordingly, i.e. the wheels of the vehicle point outward (when it is not
moving). A toe angle of 0° at the front axle ensures the best driveability
on almost any ground.

A toe angle of more than 3° toe-in (a) or toe-out (b) leads to handling
problems and reduces the speed.

The toe-on of the front wheels should not exceed 4°. The above illustrations are exaggerated to demonstrate
the difference between toe-in and toe-out.
