Abstract: A pneumatic vehicle tire includes a carcass extending between two bead cores. A belt structure is provided between the carcass and a tread strip which is connected with a pair of sidewalls. A runflat reinforcement is arranged at the inner side of each sidewall. A reinforcer is arranged within each bead portion of the tire. A bead filler extends from the bead ring along the reinforcer. To improve the runflat performance, handling and comfort properties of such a runflat tire, the reinforcer is arranged at the inner side of the bead filler. The reinforcer includes metal cords. The bead filler which extends beyond an end of the reinforcer, is made of a soft rubber compound with an IHRD hardness lower than 80.

Abstract translation: 气动车辆轮胎包括在两个胎圈芯之间延伸的胎体。 带状结构设置在胎体和与一对侧壁连接的胎面带之间。 在每个侧壁的内侧布置有漏气补强筋。 加强件布置在轮胎的每个胎圈部分内。 胎圈填料从胎圈环沿着加强件延伸。 为了改善这种漏气保用轮胎的漏气保护性能，处理和舒适性能，增强件布置在胎圈填料的内侧。 加强件包括金属帘线。 延伸超过加强件末端的珠粒填料由IHRD硬度低于80的软橡胶化合物制成。
