Method and apparatus determination of wheel assembly configuration
First Claim
1. An improved vehicle wheel assembly service system having a spindle shaft for receiving, at a spindle face with a known axial location, a wheel rim of a vehicle wheel assembly, and a processing system configured to receive measurement data associated with a wheel rim mounted against the spindle face on the spindle shaft, the improvement comprising:
- the processing system configured to utilize the received measurement data and the known axial location of said spindle face to determine a wheel rim axial displacement associated with a mounting pad surface of the wheel rim mounted against the spindle face.

Abstract
A vehicle wheel assembly service system configured to acquire measurements of the physical characteristics of a vehicle wheel assembly such as during a vehicle wheel balancing procedure, with the functionality to obtain and utilize a measurement of a vehicle wheel assembly offset or rear spacing. The vehicle wheel assembly service system is configured to display the wheel assembly offset or rear spacing measurement to an operator, and optionally, to display guidance and/or installation instructions to the operator associated with the installation of the vehicle wheel assembly on a vehicle. The displayed guidance and/or installation instructions may optionally include fitment information, vehicle performance data, or vehicle braking data.

17. A method for measuring a vehicle wheel assembly including a wheel rim, comprising:
-
mounting said wheel rim to a spindle of a vehicle wheel assembly service system by positioning a mounting pad of said wheel rim against a face of said spindle, said spindle having an axis of rotation and said face of said spindle having a known axial position along said axis of rotation; identifying an axial position along said axis of rotation associated with at least one rim edge of the wheel rim; determining within the wheel rim, a measure of axial displacement associated with said mounting pad of the wheel rim mounted against the spindle face, utilizing said identified axial position of said at least one rim edge together with said known axial position of the spindle face. - View Dependent Claims (18, 19, 20)
