6.4.4 UNBALANCE OPTIMIZATION – OPT (only for CAR mode)
This function is used to determine the best mating of tire and rim that will result in the least amount of
total unbalance of the wheel. It severs to reduce the amount of weight to be added in order to balance
the wheel. It is suitable for static unbalance exceeding 30g.
A high unbalance may indicate the improper mounting of the wheel on the
balancer. If the unbalance is excessive, it may be prudent to replace the rim, the
tire, o both. If either is replaced, do not continue with optimization. Balance the
new tire and rim and evaluate the readings.
After performing the static balance, press ..
