    • A radial tire with a circumferential spirally wound belt layer, wherein a belt layer in which one or a plurality of belt cords covered with rubber are spirally arranged generally parallel with each other in the circumferential direction of the tire is disposed by at least one layer on the outer periphery of a body ply, and the belt cords are formed so that, when the elongation of the belt cords is equal to or below a specified level, the ratio of an increase in tensile load to an increase in elongation is lowered and, when it exceeds the specified level, the ratio of the increase in tensile load is increased, whereby since, at the time of vulcanization molding, the belt cords are expanded together with unvulcanized rubber with a small tensile load and the expansion of body ply cords is not obstructed, a green tire can be expanded while holding its regular shape so that the parts thereof can be surely fitted to the mating parts for the vulcanization molding.
    • 一种具有圆周螺旋缠绕带束层的子午线轮胎,其中一个或多个被橡胶覆盖的带束帘线在轮胎的圆周方向上螺旋地布置成大致平行的带束层设置在至少一层上 主体帘布层的外周和带束帘线形成为使得当带帘线的伸长率等于或低于规定水平时,拉伸负荷的增加与伸长率的增加的比例降低, 当超过规定水平时,拉伸载荷增加的比例增加,由于在硫化成型时,带帘线与拉伸负荷小的未硫化橡胶一起膨胀,并且帘布层帘线的膨胀为 不堵塞,可以在保持其规则形状的同时膨胀生胎,使得其可以可靠地装配到用于硫化成型的配合部件上。
