A spare tire hoist may be provided. A retention cable may be used to retain a spare tire against a surface of a motor vehicle. A tensioning spring may be used to tension the retention cable when the spare tire is in a storage position. A wheel plate engages the spare tire and cooperates with the retention cable and the tensioning spring to maintain the spare tire in the storage position. The wheel plate may include an insert portion that engages a center aperture of a wheel rim of the spare tire. A flange portion that substantially surrounds the insert portion and engages a peripheral surface of the wheel rim may also be provided. A reinforcement ring may be included in the wheel plate, substantially coextensive with the insert portion and extending within a substantially hollow region of the flange portion. The reinforcement ring may provide mechanical reinforcement to the wheel plate.

Having thus described the invention, it is now claimed: 1. A wheel plate for a spare tire hoist comprising: an insert portion that engages a center aperture of a wheel rim for a spare tire, wherein at least a portion of the insert portion extends through the center aperture of the wheel rim; a flange portion that substantially surrounds the insert portion and engages a peripheral surface of the wheel rim; and a reinforcement ring, formed within the flange portion, that provides mechanical reinforcement to the wheel plate. 2. The wheel plate of claim 1, wherein the insert portion and flange portion are substantially hollow and wherein the reinforcement ring extends within a hollow region of the flange portion. 3. The wheel plate of claim 2, wherein the reinforcement ring is substantially coextensive with the insert portion. 4. The wheel plate of claim 2, wherein the hollow region of the flange portion further comprises a plurality of reinforcing ribs. 5. The wheel plate of claim 1, wherein the insert portion has a substantially circular peripheral region, radially centered along a central axis. 6. The wheel plate of claim 5, wherein the reinforcement ring is substantially circular and substantially coextensive with the peripheral region of the insert portion, and radially centered along the central axis. 7. The wheel plate of claim 5, wherein the insert portion further comprises an axial aperture, formed along the central axis of the insert portion, that admits a retention cable for retaining the wheel plate against the spare tire. 8. The wheel plate of claim 7, wherein the insert portion further comprises a spring recess that supports a tensioning spring for tensioning the retention cable. 9. The wheel plate of claim 8, wherein the spring recess is substantially frustoconical in shape. 10. The wheel plate of claim 5, further comprising: a spring swivel, retained in a seat member within the spring recess, for swivelably engaging an anterior end of the tensioning spring; and a cable crimp for engaging a posterior end of the tensioning spring, wherein the spring is tensioned between the spring swivel and the cable crimp. 11. The wheel plate of claim 5, wherein the wheel plate is formed of a composite material. 12. A spare tire hoist system comprising: a retention cable that retains a spare tire against a surface of a motor vehicle; a tensioning spring that tensions the retention cable when the spare tire is in a storage position; and, a wheel plate that engages the spare tire and cooperates with the retention cable and the tensioning spring to maintain the spare tire in the storage position, the wheel plate further comprising: an insert portion that engages a center aperture of a wheel rim of the spare tire wherein at least a portion of the insert portion extends through the center aperture of the wheel rim; a flange portion that substantially surrounds the insert portion and engages a peripheral surface of the wheel rim; and, a reinforcement ring, substantially coextensive with the insert portion and extending within a substantially hollow region of the flange portion, wherein the reinforcement ring provides mechanical reinforcement to the wheel plate. 13. The spare tire hoist system of claim 12, wherein: the tensioning cable comprises a retractable cable; and, wherein the spare tire hoist further comprises a spool for retracting and extending the cable so as to move the spare tire between a storage position and a release position. 14. The spare tire hoist system of claim 12, wherein the hollow region of the flange portion further comprises: a plurality of reinforcing ribs. 15. The spare tire hoist system of claim 12, wherein: the insert portion has a substantially circular peripheral region, radially centered along a central axis; and, the reinforcement ring is substantially circular and substantially coextensive with the peripheral region of the insert portion, and radially centered along the central axis. 16. The spare tire hoist system of claim 12, wherein the insert portion further comprises: an axial aperture, formed along a central axis of the insert portion, that admits the retention cable for retaining the wheel plate. 17. The spare tire hoist system of claim 12, wherein the insert portion further comprises: a spring recess that supports the tensioning spring for tensioning the retention cable. 18. The spare tire hoist system of claim 12, further comprising: a spring swivel, retained in a seat member within the spring recess, for swivelably engaging an anterior end of the tensioning spring; and a cable crimp for engaging a posterior end of the tensioning spring, wherein the spring is tensioned between the spring swivel and the cable crimp. 19. The spare tire hoist system of claim 12, wherein the wheel plate is formed of a composite material. 20. A spare tire hoist system comprising: a retention cable that retains a spare tire against a surface of a motor vehicle; a tensioning spring that tensions the retention cable when the spare tire is in a storage position; and, a one-piece wheel plate that engages the spare tire and cooperates with the retention cable and the tensioning spring to maintain the spare tire in the storage position, the one-piece wheel plate further comprising: an insert portion that engages a center aperture of a wheel rim of the spare tire, wherein at least a portion of the insert portion extends through the center aperture of the wheel rim; a flange portion that partially surrounds the insert portion and engages a peripheral surface of the wheel rim; and a reinforcement ring formed within the flange portion, wherein the reinforcement ring provides mechanical reinforcement to the wheel plate.
