  • Vehicle spare tire storage system having stiffening plate
    Patent number: 5860687
    Abstract: The present invention consists of a stiffening plate for a spare tire storage system that is supported by a plurality of protrusions in the form of raised beads in the tub floor. The plate is raised from the tub floor via the beads, the structure thus forming a "double thick" cross section that reduces low frequency vibration, while at the same time allowing drainage during the coating process from between the layers and which does not increase weight or cost.
