Abstract: A wheel cover assembly includes a cover and a plurality of lug wells. The cover is manufactured from a first material that is capable of being decorated with paint and/or plating. The lug wells are fabricated from a second material. The second material is chosen for its high thermal resistive characteristics. The second material insulates the first material from the thermal energy generated by the wheel hub assembly and, in particular, the brake systems of the wheel hub assembly. Each of the lug wells includes a wall having an annular recess circumscribing the interior surface of the wall and an exterior ridge extending around the periphery of the wall. The annular recess and the exterior ridge prevent the first material from flowing therepast creating a barrier of the second material used to manufacture the lug wells to the lug nuts, the conductors of the thermal energy created by the brake systems. Protrusions and elongated holes aid in the bonding of the first material to the second material.

Abstract: A retaining article secures ornamentation, namely wheel caps and wheel covers, to a wheel. The retaining article is a unitary structure. It is received by the ornamentation which has an inboard surface with a number of protrusions extending out therefrom. The protrusions are cylindrical in shape. The retaining article has a ring with a number of openings. The openings receive the protruding cylinders therein and are secured thereto by a number of tabs. The tabs are bent by the protruding cylinders. Legs extend out from the ring. The legs are forced over lug nuts which secure the wheel to a wheel hub. The legs engage a recess in the lug nuts creating a positive engagement with the lug nuts.
