Abstract: A process for making an aluminum vehicle wheel. The process includes casting the body of the wheel from aluminum. The drop center of the wheel is shot peened to seal air-transfer holes and also to increase the fatigue strength thereof. Next, both the drop center and the face of the wheel are shot peened with a finer shot to thereby reduce the surface roughness of the drop center and the face.
