Velocity Factor – Hunter GSP 9700 Road Force Wheel balancer

Velocity Factor is now a proud owner of a Hunter GSP 9700 Road Force Wheel Balancer. Those who know what a Road Force Balancer is know that there really is no comparison with a standard balancer. For those of you who do not know what a Hunter Road Force balancer is please read on. The difference is your car when properly balanced with road force feels like driving on glass on smooth surfaces.

Standard balancers know the diameter of a wheel, how wide the wheel is, and how far away it sits from the sensor that measures the run out. In a standard balancer all it is doing is looking for the slight variations of out-of-round in the wheels and tire assembly. The weights help to even out a side-to-side wobble (lateral run out) or an up and down wobble (radial run out). What is missing from the measurements is the amount of force the tire can throw off.

When balancing using a Hunter Road Force machine we are able to tell the machine exactly how far the wheel sits from the sensors that are taking the measurements, exactly the distance to just behind the spokes (where we must apply our stick on weights), the width of the wheel, and the diameter. Most importantly, a roller will apply about 1000lbs of pressure to the wheel while it is spinning to replicate what the wheel will act like when the on the road with the weight of a car on it. This roller can measure the amount of weight the tire can throw off while it is spinning. This is known as “road force”. Road force is present in new and old tires – sometimes, even more so in new tires which are caused from stiffness, lack of stiffness, or weak spots in the sidewalls of the tires. By reading the run out of the wheel and tire assembly in conjunction with the road force measurement the Hunter Road Force machine will virtually always get a wheel perfectly balanced.

What the Hunter Road Force balancer can measure is not possible on a standard balancer. Because the style of wheels used on more cars today are alloy wheels that require stick on weights it is necessary for more styles of cars to have this kind of balancing done.
