Tire and Wheel Balance Equipment Error Proofing

Tire and Wheel balance equipment does not have a capable means of determining wheel size.  The wheel size is a critical factor to correctly set balance parameters for installation of wheel balance weights.  The current detection method, called "code detect", attempts to determine wheel diameter and offset using sensors.    When wheels are erroneously read by the code detect, improper balance weights may be installed resulting in tire and wheel vibration. 

A method is proposed to use vehicle-scheduling information to communicate to the balance equipment the type of wheel and tire assembly to ensure proper balance weights.


The method utilized the vehicle scheduling information and forwards this information to the balance and audit machines to identify the correct wheel & tire combination.  Additionally, all the data from the tire and wheel assembly process is retrieved and stored in the system.

Traditional Approach

New Approach








By the use of the new system, the tire and wheel balance and audit machines are robust to proper tire and wheel identification, which assures proper balance weight installation.  The data collection allows for matching the specific balance data to a specific vehicle.  In conclusion, this method presented is more effective to identify the proper wheel and tire assembly, which leads to minimization of the residual imbalance on the components and allows for analysis of the data by a...
