Abstract
In casting an annular rim member for use in a vehicle wheel for mounting a pneumatic tire, a mold cavity is formed so that the casting has at least one of a radial overdimension or a radial underdimension and its outer surface which faces the tire has an unsegmented annular area. After the casting is solidified and removed from the mold, it is plastically deformed by radially directed cold forming or working to remove the radial overdimension or underdimension. A modular cast iron is used for the casting to provide a ductile structure whose yield point is exceeded in carrying out the plastic deformation.
