Abstract: A motor vehicle wheel and wheel support assembly for holding a wheel onto a motor vehicle which wheel may be quickly removed by unscrewing a single central knock-off nut. The assembly has a hub adapter which is bolted to the brake drum or brake disk using the conventional lug bolts and lug nuts. The hub adapter has an angled outer flange in the shape of a decagon or other multi-sided polygon. The outer surface has a slight angle such as five (5) degrees with respect to the central axis. The wheel has a mating shape and the hub adapter has a threaded extension which accepts the knock-off nut. When the wheel is placed so that its angled decagon mates with the angled decagon of the hub adapter, it may be securely held to the hub adapter by tightening a knock-off nut against the outer surface of the wheel. Thus, the wheel may be removed from the motor vehicle by simply removing the knock-off nut.
