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.
摘要翻译：本发明的漏气保用轮胎（10）包括具有独特设计的间隔开的胎圈区域（30），以包括邻近胎圈芯（32）的第一（34）和第二（36）胎圈填料。第二珠填料（36）由第一珠填料（34）和珠芯（32）限定。还提供了制造轮胎以消除固化轮胎的胎圈芯（32）处的空隙的方法。胎圈填料被制成弹性，使得轮胎可以容易地安装在轮辋上，特别是提高将轮胎（10）安装在轮辋（80）上的能力。胎圈芯（32）和填料（34,36）设计成有助于在失去充气压力的同时维持轮辋（80）上的漏气保用轮胎（10）并改善轮胎的行驶性能。
