Estimated residual wheel runout after matching:
GREEN background: after matching, the runout will be in tolerance (with respect to the
first harmonic correction limit value set in wheel runout setup).
RED background: after matching, the runout will be out of tolerance (with respect
to the first harmonic correction limit value set in wheel runout
setup), therefore, the eccentricity problem cannot be improved
with matching.
Estimated percentage gain relating to reduction of the first harmonic value obtained after
matching.
6.14.1.2.1 When to perform matching
It is advisable to perform matching if the wheel runout value is displayed on a red background and the residual wheel
runout value is displayed in the Match box on a green background.
6.14.1.2.2 How to perform matching
Turn the wheel and mark the tyre and the rim with a piece of chalk at the two points indicated in the graph. ▪
Turn the tyre on the rim until the two marks coincide. ▪
