GSP97MB Road Force Measurement® System

Solves Non-Balance-Related Vibration and Tire-Pull Problems BEFORE the Customer Leaves the Shop

The exclusive Road Force Measurement® system applies up to 635 kg (1,400 lbs.) against the tire. The loaded roller detects non-balance, radial-force-related vibrations caused by eccentricity and constructional variation of the tire and wheel. Unlike non-contact measurement, the roller samples the entire footprint of the tire including the sidewall’s contribution to ride quality.

As an additional alternative to Road Force® mode, the operator may also choose a QuickMatch® mode to quickly measure loaded runout alone.

Lack of tire uniformity is a common and often hidden source of vibration. As a tire rolls, it flexes as if it were made of springs. Vibration results when tire stiffness is not uniform.

GSP97MB’s Inflation Station* provides proper inflation pressure and automatic prompting for the operator to ensure accurate testing and customer satisfaction.

Non-contact runout measurement systems often provide inconsistent results and do not take into consideration the contribution of tire sidewalls to vibration problems.

The GSP97MB 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.

The GSP97MB slowly rotates the wheel automatically during measurement.* The GSP97MB then calculates the contributions of the tire and the rim to the vibration problem and presents the technician with easy-to-follow repair instructions.

Slippage detection is also automatically monitored to ensure the technician achieves accurate measurements.

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

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

* Patented Feature

The optional GSP97MB integrated pneumatic Wheel Lift System helps technicians safely service today’s oversized custom, light-truck and medium-duty commercial wheels quickly and easily.

(The pneumatic wheel lift option must be ordered with the machine and cannot be added as an upgrade to existing units in the field.)

Benefits

• Helps center heavy wheels up to 80 kg (175 lbs.) more accurately for better balancing results.
• Saves valuable workspace on the shop floor and avoids the excessive costs associated with bulky stand-alone wheel lift units.
• “Drop-away” feature automatically lowers the lift when the hood is closed – eliminates procedural steps associated with stand-alone wheel lift units.

The patented ForceMatching 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 matchmount 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 new car vehicle manufacturers, the GSP97MB 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.
