Abstract
A method of manufacturing vehicle wheels from a disc blank, in which the wheel has rim portions of uniform thickness and different lengths. The wheel is made by spin forging the edge portion of the disc to form an angled portion, splitting the disc into two split portions one of which has the angled portion joined at its end and forming the split portions into a desired rim configuration. A groove may be formed on the periphery of the angled portion to precisely fix the location of the split.
