Abstract: A wheel cover retention system for a wheel having a plurality of lug studs extending through the wheel. The wheel cover includes a base having an outboard surface and an inboard surface opposite the outboard surface, and also having lug towers formed integrally therein and projecting inboard from the inboard surface. The wheel cover includes thermal isolator itegrally fixed coaxially and apically to each of the lug towers, each lug stud extending through each lug tower and each thermal isolator. A lug nut threads to each lug stud to fasten the wheel cover between the wheel and a shoulder on the lug nut. The thermal isolator thermally isolates the base of the wheel cover from heat transfer from a brake component through the lug stud and nut.
