A wheel cover mounting for plastic wheel covers (10) comprising a mounting portion (14) positioned in axial alignment with and spaced radially inward from a facing surface portion (16) of a vehicle wheel (18). A spring wire retainer ring (32) including radially outwardly extending projections (34) spaced circumferentially around the ring (32) in a substantially flat plane are received through circumferentially spaced openings (73, 77) in the mounting portion (14) of the wheel cover (10). At least one, and preferably most if not all, of the openings (73, 77) are defined by guide walls (72, 74, 76, 78) circumferentially spaced apart a distance greater than the circumferential width of the projections (34) in order to reduce frictional forces between the projections (34) and the lugs (20-30) and maximize the forces retaining the wheel cover (10) on the wheel (18) and in a fixed position with the wheel (18). The forces maintaining fixed positioning can be further increased by anti-rotational means (38) interposed between the wheel cover (10) and a surface (16) fixed for rotation with the wheel to resist relative rotational displacement of the wheel cover (10) with respect to the wheel (18). Preferably, two spring clips (38) including a resilient tang (58) are disposed at diametrically opposed positions of the wheel cover (10) with their tangs (58) radially inclined in opposite rotational directions. The openings (73) in the mounting portion near the spring clips are defined by guide walls (72, 74) spaced apart from each other a distance greater than the width of the projection (34) extending through the opening so that the loading force of the spring clip (38) does not affect the retaining force applied by the spring wire retainer (32). |
