Abstract

For mounting relatively thick wheels ("mag" wheels, etc.) on the hubs of motor vehicles, a sleeve is provided, internally threaded to screw onto the mounting stud, and externally formed as a smooth cylinder dimensioned to fit snugly in the stud hole of the wheel, the sleeve being of a length to extend only part way (usually about half way) through the thickness of the wheel. The sleeve is screwed onto the stud tight against the hub. When the wheel is placed on the sleeves (one on each stud, of course), the lug nuts are then placed on the studs and tightened as usual. The sleeves are of such length relative to the lengths of the cylindrical shanks of the nuts that there is a slight gap between sleeve and shank. The sleeve supports that portion of the wheel thickness closest to the hub, and the shank of the nut supports that portion farther from the hub. Flexure forces on the studs are reduced because of the lesser leverage effect, and there is reduced risk of damage to the wheel or the studs under severe driving conditions. Also, mounting of the wheel is facilitated.
