Vehicle wheel components of the disclosure are manufactured by a foam construction wherein structural members are secured to each other to define a cavity that receives foam which adheres to the members so as to cooperate therewith as a load bearing component. The foam construction is utilized in one embodiment to provide a wheel hub that is mounted on a vehicle axle so as to rotatably support a vehicle wheel on the axle. A wheel of a second embodiment includes a disc and rim that are each made with the foam construction. The disc is fixedly mounted on a wheel hub and the rim is detachably secured to the disc so that different rims may be mounted on the disc. A vehicle wheel assembly of a third embodiment is particularly designed for heavy-duty truck or trailer use. This heavy-duty wheel assembly includes a pair of rims having the foam construction and detachably secured to a disc portion of a hub mounted on a vehicle axle.
