Abstract: An annular reinforcement structure is provided having a first reinforcement band and a second reinforcement band in a spaced-apart, concentric relationship, and a cast-in-place core material positioned between the first and second reinforcement bands and bonded thereto.

Abstract: A non-pneumatic wheel assembly is provided. More particularly, a non-pneumatic wheel assembly is provided having a removable hub i.e., a hub that may be separated from the remainder of the wheel assembly. The hub may be reused and other portions of the non-pneumatic wheel assembly replaced as needed. In addition, the hub may be constructed from a different material than used for other portions of the non-pneumatic wheel.

Abstract: The run-flat tire (10) of this invention includes spaced apart bead areas (30) having a unique design to include first (34) and second (36) bead fillers adjacent a bead core (32). The second bead filler (36) is bounded by the first bead filler (34) and bead core (32). The method for manufacturing the tire to eliminate voids at the bead core (32) of the cured tire is also provided. The bead fillers are made to be resilient so that the tire can be easily mounted on a rim, particularly improving the ability to mount a run-flat tire (10) on a rim (80). The bead core (32) and fillers (34, 36) are designed for helping to sustain the run-flat tire (10) on the rim (80) with a loss of inflation pressure and to improve the running performance of the tire.

Abstract: The run-flat tire has a tread for contacting a ground surface and a belt package with belt plies interior to the tread for support of the tread. A plurality of radially reinforced carcass layers are positioned interior to the belt plies and include at least one carcass layer that extends between spaced apart annular beads. The tire has a pair of sidewalls each extending radially inward from shoulders at lateral edges of the belt package to the annular beads. The sidewalls have a plurality of sidewall stiffening members to support the tire during a loss of inflation pressure. The carcass layers are disposed with the sidewall stiffening members to help support the run-flat tire with a loss of inflation pressure.
