Abstract
A method of forming a one piece vehicle wheel is disclosed which method includes the steps of initially forging a rough vehicle wheel shape which is then subjected to a series of spinning operations to contour the rim portion thereof. Part of the final contouring of the rim portion of the wheel is performed without mandrel backing. The entire final contouring is performed after a solution heat treatment that imparts a T4 material condition thereto in order to assure accurate formation thereof. Additionally, if desired, final machining and/or trimming operations may be performed without removing the wheel from the final contouring apparatus.
