The invention relates to the technical field of tire manufacturing, in particular to a radial tire with side wrapping reinforcement of a steel wire ring composite part and a forming method of the radial tire. The method comprises the following steps that a reinforcing material layer is attached to the outer side face of a composite part composed of a steel wire ring and apex, the distance between the lower end of the reinforcing material layer and the bottom of the steel wire ring is a, the length of the reinforcing material layer is b, and the value range of a is 0-25 mm; and the value range of the b value is 40-60 mm. According to the method, the occurrence rate of appearance defects such as sidewall rubber shortage and sidewall cracks can be reduced while the defects are solved and improved.

    本发明涉及轮胎制造技术领域,尤其涉及一种钢丝圈复合件侧包补强的子午线轮胎及其成型方法。该方法包括以下的步骤:通过在钢丝圈和三角胶构成的复合件的外侧面上贴合补强材料层,补强材料层的下端与钢丝圈的底部的间距为a,补强材料层的长度为b,a值取值范围0‑25mm;b值取值范围40‑60mm。该方法在解决和改善上述缺陷问题的同时也可以减少胎侧缺胶、胎侧裂口等外观病疵发生率。
