Balancing with PWS's Hunter Engineering GSP9700 Vibration
Control System
Smooth-rolling tires and wheels can be the difference between
having a vibration-free driving experience or a shaky one.
The
Hunter Engineering GSP9700 Vibration Control System used by
Prince Wheel Service's technicians goes far beyond the
traditional capabilities of a wheel balancer. In addition to
rectifying the inevitable wheel and tire imbalance, the
GSP9700 Vibration Control System also "road tests" the
mounted assembly to confirm virtually every aspect of a tire
and wheel combination that might contribute to a vibration.
The GSP9700 Vibration Control System includes Hunter's
exclusive Road Force Measurement System to help detect
potential tire uniformity causes of vibration that are not
balance-related. This system utilizes a "road roller" which
applies up to 1,400 pounds (635 kg) of force against the
wheel and tire assembly to measure their combined
uniformity. This simulated road force test helps verify if
the assembly is "round" when rolling under load.
The GSP9700 Vibration Control System can also measure lateral
and radial rim runout (out of roundness or side-to-side
movement) to identify and separate wheel runout from tire
runout.
If the wheel and tire are at the edge of acceptable
tolerances, Hunter's patented ForceMatching(TM) feature is
used to align the high point of the tire with the low spot
of the rim.
