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.
