5.11Optimization/WeightMinimization

5.11.1GeneralOptimizationisafinerformofmatching.

Duringtheopto–rideprocedurestherimandtyre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tyre.In

thiscasetheunbalanceoftherimcanbereadjusted

relativetotheunbalanceofthetyresuchthatthe

unbalancescompensateeachotherandthesmallest

possibleweightforunbalancecorrectionisdetermined.



Compensationofunbalanceoftheclampingdeviceis

cancelledbystartinganoptimizationorminimization

run(C47.1.1).Preparation:Makesurethetyreis

correctlymountedonrimandinflatedtospecified

inflationpressure(mountingguideribofthetyremust

becorrectlyseated).Clampthewheel.Entercorrectrim

dimensions,orcheckexistinginputsforcorrectness.

SelecttheMODE‐keyuntiltheMinimizationindicator

blinks. The“M”indicatorwillstartblinking.Thedisplay

now equalsFigure5‐31.Note:TheMODE‐indicatorwillbe

on and theMinimizationindicatorwillblink.Ifthe

Minimization indicatordoesnotblink,checkifaNORMAL

wheel is selected.•SelectENTER(1,Fig.5‐32).Toexitthe
