Measure Rim Runout and Force Matching

Rim runout can be measured without removing the tire...

The GSP9700 measures lateral and radial rim runout without removing the tire from the rim and quickly indicates if runout is tire-related. Runout can also be measured at the actual bead seat on a bare rim.

... or directly at the bead seat on a bare rim.

The GSP9700 slowly rotates the wheel automatically during measurement.* The GSP9700 then calculates the contributions of the tire and the rim to the vibration problem and presents the technician with easy-to-follow repair instructions.

Hunter’s patented ForceMatch® feature cancels the stiffest point of tire radial force variation with the low spot on the rim. This helps eliminate vibration by minimizing the effects of radial force variation and rim runout.

QuickMatch® measurement may also be chosen to quickly audit and match-mount with loaded runout instead of force calculations if greater time savings during cycle time is preferred.

Once the correction is completed, the technician can continue with a precision wheel balance by instantly choosing the balancing method without key closure steps.

Offering the same service as vehicle manufacturers, the GSP9700 matches the stiffest area or high spot on the tire with the lowest spot on the rim to cancel vibration caused by radial force variation and provide the smoothest possible ride.
