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 translation: 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。

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. The spaced apart beads have a unique design including bead cores placed at a predetermined diameter with respect to a rim diameter, dual bead fillers above the bead cores, a heel corner spaced at a radial gap distance from a rim flange and rim interface components having a seat interface distance below the bead core for mounting the run-flat tire on a conventional rim and for sustaining the run-flat tire on the conventional rim with a loss of inflation pressure within the run-flat tire.
Abstract translation: 漏气保用轮胎具有用于接触地面的胎面和带束层包装，胎面内部具有用于胎面支撑的胎面的带束层。 多个径向增强的胎体层位于带束层的内部，并且包括在间隔开的环形珠之间延伸的至少一个胎体层。 轮胎具有一对侧壁，每个侧壁从带包装的侧边缘处的肩部径向向内延伸到环形珠。 侧壁具有多个侧壁加强构件，以在损失充气压力的同时支撑轮胎。 胎体层与侧壁加强构件一起设置，以有助于在失去充气压力的情况下支撑漏气保用轮胎。 间隔开的珠具有独特的设计，包括相对于轮缘直径放置在预定直径的胎圈芯，在胎圈芯上方的双胎圈填料，与轮缘凸缘间隔距离的跟部角和与轮缘接合部分 位于胎圈芯之下的座接口距离，用于将漏气保用轮胎安装在传统的轮辋上，并且用于在漏气轮胎中损失充气压力的情况下在常规轮辋上维持漏气保用轮胎。
