5.10 Optimization / Weight
Minimization
5.10.1

General

Optimization is a fi ner form of matching.
During the opto–ride procedures the rim and tire are
adjusted relative to each other on the basis of different
unbalance measurements. This generally means that,
where present, lateral and radial run–out and radial
and lateral force variations are reduced and thus
wheel running conditions optimized. In addition, the
mass (balance weight) necessary for balancing can
be reduced.
If optimization is not desired, it is possible to achieve
weight minimization (so–called matching).
This is e. g. possible if the rim does not exhibit geometric
deformations, in other words, when unsmooth wheel
running conditions are a result of a non–uniform tire.
In this case the unbalance of the rim can be readjusted
relative to the unbalance of the tire such that the
unbalances compensate each other and the smallest
possible weight for unbalance correction is determined.
5.10.2 Instructions for the Optimization/
Weight Minimization Programs
optimisation/weight minimisation, the wheel balancer
can be used as a conventional wheel balancer by
another operator.
For this purpose, press the OPERATOR key, thus
aborting the weight optimisation/minimisation program
and switching to RIM DATA ENTRY screen. The
electronic control unit will then store step 3, 7, 11 of
the current program, the rim dimensions and all data
measured so far.
If another optimisation/minimisation run is to be started
after an interruption, select the corresponding user and
press RESUME OPT/MIN key (21, Fig. 5-32).
The compensation carried out by the wheel clamping
device is cancelled by starting an optimisation or
minimisation cycle.
