2.3 SmartWeight

 Balancing Technology Dynamic Weight Planes 
SmartWeight requires the operator to enter at least two weight planes. This balancing 
method will automatically determine if one or both weight planes require a weight to 
be added. This eliminates “blinded” static single plane balancing, which alone may 
not be sufficient to solve couple vibration issues. 
The GSP9720JLR balancer offers two primary ways to balance tires:  
1. SmartWeight® Balancing Technology 
2.  Traditional balancing technology 
Both of these methods can balance tires dynamically. The main difference is 
SmartWeight will reduce the amount of corrective weight in a basic wheel balancing 
situation and automatically optimize static force reduction and single plane weight 
placement.
2.4 Using SmartWeight

 Balancing Technology 
The SmartWeight balancing forces display varies greatly from the standard balancing 
display. SmartWeight tire graphs independently display the static and couple forces 
within a tire/wheel assembly. A single plane (static) mode and non-round off modes 
are no longer necessary. The traditional “static” and “dynamic” modes are eliminated. 
The traditional non-round off mode is eliminated. These modes are no longer 
necessary with SmartWeight balancing. 
The red-dotted line represents the acceptable amount of force the tire and wheel 
assembly can have that will not result in a ride problem. Any forces below that line 
will be shown in green. Any forces that are above that level will be shown in red and 
indicate an excessive amount of force. 
Install the tire/wheel assembly as normal. Rim measurements are not required to 
determine if the balance forces are exceeded. Lower the hood and spin.
