A wheel cover formed of plastic or metal having a wire ring supported on the inboard face thereof. The ring is formed with a plurality of circumferentially spaced, radially outwardly extending, U-shaped projections designed to frictionally engage an annular surface on the wheel rim to retain the cover thereon. The radially outermost portion of the bight section of each projection is formed with a sharp biting edge face inclined both to the plane of the wheel cover and to the axis of the wheel cover so as to provide substantial resistance of the cover to rotation and axial outward displacement relative to the wheel. |
