    • Pneumatic vehicle tyre comprising a carcass (3), wherein the carcass (3) has two carcass plies (31, 32), wherein each carcass ply (31, 32) has reinforcements which are arranged inside the carcass ply (31, 32) substantially parallel to each other. The problem addressed by the invention is to provide a pneumatic vehicle tyre which likewise creates a high quality impression of sufficient robustness to a viewer and, in the process, is cheaper to produce and has a reduced rolling resistance. The invention is characterised in that the product EF1 of the average modulus of elasticity of the reinforcements, as measured with an extension of 2%, of the first carcass ply (31) and the thread density of the reinforcements of the first carcass ply (31), and the product EF2 of the average modulus of elasticity of the reinforcements of the second carcass ply (32) and the thread density of reinforcements of the second carcass ply (32), satisfy the relationship EF1 > EF2.
    • 一种充气车辆轮胎,包括胎体(3),其中胎体(3)具有两个胎体帘布层(31,32),其中每个胎体帘布层(31,32)具有增强件,所述增强件基本上布置在胎体帘布层 相互平行。 本发明解决的问题是提供一种充气车辆轮胎,其同样产生对观察者具有足够坚固性的高质量印象,并且在该过程中,生产更便宜并且具有减小的滚动阻力。 本发明的特征在于,第一胎体帘布层(31)的增强材料的平均弹性模量(以2%的延伸率测量)和第一胎体帘布层(31)的增强材料的线密度 )以及第二胎体帘布层(32)的增强件的平均弹性模量和第二胎体帘布层(32)的增强件的线密度的乘积EF2满足EF1> EF2的关系。
