Hunter said its third generation GSP9700 Road Force Measurement System supports the same exclusive and patented features that set it apart from conventional wheel balancers, as well as an updated design and new features to further improve wheel service productivity. The new balancer uses a “road roller” to perform a simulated road test on the wheel assembly to identify vibration and tire pull problems. The Smart weight balancing technology minimizes correct weight usage by reducing wheel weight costs 30% to 40%, saving time with more single-spin balances and providing a better overall balance. Hunter says the new GSP9700 is used by automobile and tire manufacturers and is approved for their tire dealer equipment programs and recommended by their service bulletins.
