Abstract: A theft-resistant tire mounting assembly for deterring theft of wheels includes a wheel rim. Recesses are positioned proximate to a center of the wheel rim. An opening is centrally positioned in each recess. Nuts are configured to threadedly couple to the stud bolts of a wheel hub. One nut comprises a locknut, which has a second end that comprises an exposed face. A perimeter of the exposed face is complementary to the opening, and a keyhole is positioned in the exposed face. The assembly includes an adapter that has a key end, which is complementary to the exposed face. The locknut is incompatible with the socket of the tire iron, and a wrench is not couplable to a locknut that is threaded to the stud bolt. The key end is positioned to couple to the exposed face such that torque from the tire iron is transferable to the locknut.
