A pneumatic vehicle tire has a carcass (2) having a textile carcass strength element, and a carcass (3) having a textile carcass strength element. A belt (7) arranged radially outside the carcass; and a belt ply of a belt (8), which is arranged radially outside the belt (7), the belt ply having textile cords (20) as strength elements, which are arranged substantially parallel to one another and embedded in an elastomeric material (11), the cords (20) each having exactly two threads, wherein the two yarns are polyamide 6.6 (PA 6.6) yarns, which have the same linear density and are end-twisted together to form the cord (20). The problem is to further improve the high-speed capability. This is achieved in that the cords (20) have a tangent modulus of 9.3 N/% to 14 N/%, preferably 9.5 N/% to 13 N/%, particularly preferably 11 N/% to 12.5 N/%, at an elongation of 4%.
一种车辆充气轮胎,该车辆充气轮胎具有:胎体(2),该胎体具有织物胎体强度元件;带束(7),该带束径向布置在该胎体外侧;以及带束箍带(8)的带束箍带帘布层,该带束箍带帘布层径向布置在该带束(7)外侧,其中该带束箍带帘布层具有作为强度元件的织物帘线(20),这些织物帘线基本上彼此平行布置并嵌入弹性体材料(11)中,其中这些帘线(20)各自具有恰好两条纱线,其中该两条纱线是聚酰胺6.6(PA 6.6)纱线,这些纱线具有相同的线性密度并端捻在一起以形成该帘线(20)。问题是进一步提高高速能力。这是这样实现的,其中这些帘线(20)在4%的伸长率下具有9.3N/%至14N/%,优选地9.5N/%至13N/%,特别优选地11N/%至12.5N/%的切线模量。
