Aufbau von Wulstkernen und Wulstfüller

摘要

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.
