Vehicle wheel rim with integral spare tire

A vehicle wheel rim with integral spare tire comprising:

• a main wheel and an integral spare tire;
• wherein the integral spare tire is a spare tire that is coupled to the main wheel, physically smaller in size than a main tire and is immediately available for use when the main tire fails;
• wherein the main wheel comprises a main rim well, an inner flange, an outer flange, a center disc, and a plurality of lug holes;
• wherein the main wheel is a circular, metal component that mounts to an axle of a vehicle;
• wherein the main rim well is a cylindrical tube oriented such that a longitudinal axis of the rim well is aligned with and coincides with a longitudinal axis of the axle;
• wherein the inner flange is a projecting collar that circumscribes the main rim well at the inside edge of the main rim well;
• wherein the inner flange is oriented to project away from the center of the main rim well;
• wherein the outer flange is a projecting collar that circumscribes the main rim well at the outside edge of the main rim well;
• wherein the outer flange is oriented to project away from the center of the main rim well;
• wherein the inner flange and the outer flange together comprise contact points and restraints for the bead of the main tire;
• wherein a main tire inner bead presses against the inner flange when the main tire is inflated and a main tire outer bead presses against the outer flange when the main tire is inflated;
• wherein the seal formed by the main tire inner bead pressing against the inner flange and the main tire outer bead pressing against the outer flange holds air in the main tire;
• wherein the center disc comprises the center of the main wheel;
• wherein the centermost portion of the center disc is oriented to lie in a plane that is perpendicular to the longitudinal axis of the rim well;
• wherein the centermost portion of the center disc comprises the plurality of lug holes which allow the main wheel to be mounted onto the axle;
• wherein the plurality of lug holes are arranged to form a ring that is centered on the main wheel and oriented to pass through the center disc from inside to outside;
• wherein the diameter of the ring is configured to match the diameter of a plurality of lug bolts on a hub of the axle;
• wherein the remainder of the center disc that is outside of the plurality of lug holes extend to and couple to the main rim well of the main wheel;
• wherein the remainder of the center disc is planar or is concave;
• wherein the integral spare tire comprises a safety rim well, a safety rim, and a safety tire;
• wherein the integral spare tire is a non-pneumatic, emergency tire that is integrated with the main wheel;
• wherein the integral spare tire is located on the inside of the main wheel and thus is hidden by the main tire;
• wherein an outer diameter of the spare tire is smaller than a diameter of the main tire when the main tire is inflated;
• wherein the outer diameter of the spare tire is larger than a diameter of the main rim well;
• wherein the integral spare tire is suspended above a road surface when the main tire is inflated;
• wherein the integral spare tire contacts the road surface when the main tire is deflated;
• wherein the safety rim well is a cylindrical tube oriented such that a longitudinal axis of the safety rim well is aligned with and coincides with the longitudinal axis of the axle and with the longitudinal axis of the main rim well;
• wherein the safety rim well is coupled to the main wheel so that the safety rim well turns with the main wheel.
