The invention relates to a utility vehicle pneumatic tyre having a meridian design, in particular for trucks, buses and truck trailers, comprising a four-layer or multi-layer belt (4) comprising a barrier layer (5), two working layers (6, 8) and a 0 DEG layer (7), in which a steel cord (10) is arranged, the steel cords comprise at least two strands (11), each strand having at least six steel filaments (12), and wherein each strand has an identical first twist angle alpha and the steel cord has a second twist angle beta by a twisting process. The invention is characterized in that the steel cord (10) of the 0-degree layer (7) has a 2 to 4 x n x d configuration, where n = 6 to 8 and d = 0.15 mm to 0.29 mm, where the above configuration is that the steel cord (10) has two to four strands (11) twisted together, where each strand (10) contains six to eight steel filaments (12), where each steel filament (12) of the steel cord (10) has the same filament diameter (13), and where the steel filaments (12) of the steel cord (10) have the same filament diameter (13). The sum of the twist angle alpha of the strands (11) and the twist angle beta of the steel cord is between 37 DEG and 50 DEG, preferably between 37 DEG and 45 DEG, particularly preferably between 38.5 DEG and 42.5 DEG, and most particularly preferably between 39.3 DEG and 41.3 DEG.

    本发明涉及一种具有子午线设计、尤其是用于卡车、公共汽车和卡车拖车的多用途车辆充气轮胎,该多用途车辆充气轮胎具有四层或多层式带束(4),该四层或多层式带束包括阻挡层(5)、两个工作层(6,8)、以及0°层(7),其中,钢丝帘线(10)布置在0°层(7)中,这些钢丝帘线包括至少两根股线(11),每根股线具有至少六根钢细丝(12),并且其中,通过加捻过程使得每根股线具有相同的第一捻角α并且使得钢丝帘线具有第二捻角β。本发明的特征在于,0°层(7)的钢丝帘线(10)具有2至4x n x d构造,其中,n=6至8并且d=0.15mm至0.29mm,其中,上述构造是指钢丝帘线(10)具有二至四根捻绕在一起的股线(11),其中,每根股线(10)包含六至八根钢细丝(12),其中,钢丝帘线(10)的每根钢细丝(12)具有相同的细丝直径(13),并且其中,股线(11)的捻角α与钢丝帘线的捻角β之和在37°与50°之间、优选地在37°与45°之间、特别优选地在38.5°与42.5°之间、并且最特别优选地在39.3°与41.3°之间。
