Examination of the wheel taper requires a special measuring cycle to be enabled using the button and
requires a slightly longer cycle time.
After the measurement, you obtain:
GREEN indicator: wheel NOT TAPERED and in good conditions
YELLOW indicator: wheel SLIGHTLY TAPERED
to the right
or to the left
as indicated in the graph:
it is advisable to check the wheel soon.
RED indicator: TAPERED wheel
to the right
or to the left
as indicated in the graph.
Check the taper of the wheel to be mounted on the same axle, assess if there is any
toe-inor replace the wheel.
The wheel taper measurement is important to solve any vehicle drift problems. Wheels tapered in the same
direction and mounted on the same axle might lead to the vehicle having problems in maintaining the trajec-
tory on a straight line.
