The invention relates to a radial vehicle tyre, comprising:-two bead regions having a bead core,-a carcass insert extending around the bead core and having a carcass turn-up extending towards a tyre wall,-at least one rubber band, the invention relates to a tyre comprising at least one rubber band forming the outer surface of the bead region and consisting of a first rubber band part consisting of a first rubber mixture and a second rubber band part consisting of a second rubber mixture, the first rubber band part extending along the carcass turn-up, the second rubber band part extending along the carcass turn-up, the first rubber band part extending along the carcass turn-up, and the second rubber band part extending along the carcass turn-up. And-the second rubber band portion is formed such that, after mounting on the rim, the second rubber band portion is positioned at least partially between the bead core and the rim, characterized in that the rebound resilience of the first rubber mixture according to DIN 53512 at 20 DEG C is in the range of 20% and 80%, and the rebound resilience of the second rubber mixture according to DIN 53512 at 20 DEG C is in the range of 20% and 80%. And the resilience of the second rubber mixture likewise measured according to DIN 53512 at 20 DEG C differs from the resilience of the first rubber mixture. The invention also relates to the use of the rubber blanket and to a vehicle wheel system comprising a radial vehicle tyre.

    本发明涉及一种径向车辆轮胎,包括:‑两个胎圈区域,这两个胎圈区域具有胎圈芯,‑胎体嵌件,该胎体嵌件围绕胎圈芯延伸并且具有朝向胎壁延伸的胎体反包,‑至少一个橡胶垫带,该至少一个橡胶垫带形成胎圈区域的外表面并且由第一橡胶垫带部分和第二橡胶垫带部分组成,该第一橡胶垫带部分由第一橡胶混合物组成,该第二橡胶垫带部分由第二橡胶混合物组成,其中,‑第一橡胶垫带部分沿着胎体反包延伸,并且‑第二橡胶垫带部分被形成为使得在安装在轮辋上之后,第二橡胶垫带部分至少部分地定位在胎圈芯与轮辋之间,其特征在于,第一橡胶混合物的在20℃下根据DIN 53512的回弹性在20%和80%的范围内,并且第二橡胶混合物的同样在20℃下根据DIN 53512测得的回弹性与第一橡胶混合物的回弹性不同。本发明还涉及一种橡胶垫带的用途以及一种包括径向车辆轮胎的车辆车轮系统。
