4.4 QuickMatch® Tire and Wheel Mounting
QuickMatch® tire and wheel mounting procedure is a method of aligning the high
spot of the radial loaded runout first harmonic (once-per-revolution component) with
the average low spot of the radial rim runout first harmonic to decrease vibration in
the wheel assembly. Refer to “Theory of Operation,” page 133.
QuickMatch® is available as a softkey selection if enabled from the setup menu. This
method of match-mounting does not calculate Road Force, however, displays runout
measurements of the tire and wheel with faster cycle time compared to road force
measurement. QuickMatch® with runout is faster than Road Force, however, is not
recommended as the best choice for diagnostic use and vibration problem solving.
After measuring the assemblies loaded runout, it prompts the operator “QuickMatch?
Yes or No”. Refer to “Rim Runout Measurements,” page 63. If the operator chooses
“Yes”, the GSP9720JLR will then prompt the operator to measure rim runout.
After measuring rim runout, results are shown on the “Current Runout” popup screen.
NOTE: QuickMatch® tire and wheel mounting procedure results and
benefits are not computed until rim runout is measured.
The “Current Runout” screen will display a message informing you if using
QuickMatch® will be beneficial.

Road Force Audit Mode
When in Road Force Audit mode, the balancer will run a QuickMatch measurement
on every wheel that is balanced. If the loaded runout tolerance is exceeded, the
balancer will automatically perform a full Road Force measurement on the current
wheel assembly and display Road Force results instead of loaded runout.
This is ideal for shops who want to check every assembly without spending extra
time performing a Road Force measurement on every wheel.
To enable Road Force Audit mode, refer to “Road Force Audit Mode” on page 118.
NOTE: When Road Force Audit is enabled, there is no longer a
selection between QuickMatch and Road Force, since both
are technically enabled at that point.
