The Centrue/Pierce Process for Improved Wheel Uniformity Control

THIS IS A PRESENTATION of a new method of manufacturing stamped steel automotive wheels that results in better uniformity control for improved ride. The process involves the production of a wheel assembly having a semi-finished bolt circle and pilot area, then finishing this area relative to the tire bead seats.

The benefits of this process are reduced radial non-uniformity, reduced non-concentricity of bolt circle to center pilot, and the ability to control the location of the low point of the first harmonic of radial non-uniformity for purposes of tire-wheel match mounting.
