The GSP 9700 extends far beyond the traditional functions of a wheel balancer and "road tests" the wheel before it's on the vehicle to eliminate vibration problems. Hunter's exclusive Road Force Measurement™ System utilizes a "road roller" to measure uniformity of the wheel and tire, simulating a road force test and verifying if the assembly is "round when rolling."

The GSP 9700 will automatically diagnose any vibration problems. With this machine, we can locate and eliminate virtually every cause of vibration relating to the tire and rim and offer our customers 100% quality control.

Often confused with wheel alignment, a properly balanced wheel is a beautiful, perfectly tuned wheel-tire combination. This is accomplished by placing measured lead weights on the opposite side of the "heavy spot"—the noticeable tread wear on your unbalanced tire.

How do I know if I need my wheels balanced?

Is your vehicle vibrating at certain speeds, say, between 50 and 70 mph? If so, chances are your wheel is out of balance. One section of your tire is heavier than the other because it's endured more exposure to the friction and heat of the road. Come in for prompt, professional service—most people are very satisfied with the difference such a simple and inexpensive procedure makes. Look for these signs, and if you find either one, come see us:

• Scalloped, erratic wear pattern on tires.
• Vibration in steering wheel, seat, or floorboard at certain speeds.
