The invention relates to the field of tires, in particular to a radial tire which comprises apex, a reinforcing layer, a steel wire ring and seam allowance protection rubber. The reinforcing layer wraps the apex; the steel wire ring is arranged in the apex; the seam allowance protection rubber wraps the outer side of the reinforcing layer, and the seam allowance protection rubber is connected with the lining rubber after bypassing the steel wire ring; wherein the apex has a first height h1 in the circumferential direction of the tire, h1 = tire section height SH * a first coefficient a, and the value range of the first coefficient a is 0.18-0.32. The first height h1 of the apex in the circumferential direction of the tire is designed, and the value range of the first coefficient a is limited to be adjustable, so that the parameter of the first height h1 of the apex is adjustable, and the ring failure performance of the radial tire in a high-speed performance test at the inclination angle of-3 degrees can be improved.

    本发明涉及轮胎领域,尤其涉及一种子午线轮胎,其中,子午线轮胎包括:三角胶、补强层、钢丝圈、子口护胶;补强层包裹于三角胶的外部;钢丝圈设于三角胶的内部;子口护胶包裹于补强层的外侧,子口护胶绕过钢丝圈后连接内衬胶;其中,三角胶具有沿轮胎周向的第一高度h1,h1=轮胎断面高度SH*第一系数a,第一系数a的取值范围为0.18~0.32。通过设计三角胶沿轮胎周向的第一高度h1,限定第一系数a的取值范围可调节,从而三角胶的第一高度h1参数可调节,有助于提升子午线轮胎在‑3°倾角高速性能测试圈部失效性能。
