| description | The invention relates to a tyre (1) for passenger vehicles, the rolling resistance performance of which has been improved without compromising the lateral cornering stiffness. The bead (50) is softened by using a low hysteresis material. The lateral cornering stiffness is increased by controlling the contact between the bead (50) and the mounting rim (100). A length LADC of the rim contact curve is measured in the at least one first bead in a first section located in the contact area. A length LCJ of the rim contact curve is measured in at least one second bead in a second section opposite the contact area with respect to the axis of rotation of the tire. The ratio of the difference in length of the rim contact curves in the two zones, 100 * (LADC-LCJ)/LCJ, is greater than or equal to 30.
本发明涉及一种用于客运车辆的轮胎(1)，其滚动阻力性能已得到改善，而且不会损害横向侧偏刚度。胎圈(50)通过使用低滞后性材料而柔化。通过控制胎圈(50)与安装轮辋(100)之间的接触来使横向侧偏刚度增加。在位于接触区域的第一区部中，在至少一个第一胎圈中，测量轮辋接触曲线的长度LADC。在相对于轮胎的旋转轴线而言与接触区域相对的第二区部中，在至少一个第二胎圈中，测量轮辋接触曲线的长度LCJ。两个区部中的轮辋接触曲线的长度差的比率，即100*(LA |
