ABSTRACT OF THE INVENTION A multiple part wheel cover adapted to simulate a wire spoke wheel when attached to a vehicle wheel comprises a retainer plate, separate inner and outer one-piece spoke as- semblies, and a hub cover. The retainer plate has a peri- pheral rim around a central hub and is adapted to be-atta- ched to the vehicle wheel. The rim also has two sets of spoke receiving recesses therein opening generally radially. Each spoke assembly comprises a one-piece injection molded plastic having an annular member of smaller diameter than the rim and integral with the radially inner ends of a plurality of spokes which extend from their inner ends to outer ends confined respectively within one of each of the two sets of recesses. The annular member of the inner spoke assembly lies adjacent to and axially outwardly of the hub of the retainer plate. The annular member of the outer spoke assembly lies adjacent to and axially outwardly of the annular member of the inner spoke assembly. The hub cover lies adjacent to and axially outwardly of the outer annular member and is clamped toward the hub to secure all the parts together. The wheel cover is fabricated by first forming the separate parts. The retainer plate and inner and outer spoke assemblies are then supported coaxially in predeter- mined axial spacing. Bending force is applied to the spokes to bend them resiliently within their elastic limits sufficiently to align their radially outer ends with their respective recesses in the rim. Thereafter the bending force is progressively relaxed and the supported parts are simultaneously and progressively moved coaxially toward each other to cause the outer ends of the spokes to enter their recesses as the spokes straighten resiliently. The parts are then secured together by clamping the hub cover toward the hub of the retainer plate, whereupon removal of the outer ends of the spokes from their recesses is pre- vented.
