The invention relates to the technical field of tire manufacturing, in particular to a reinforced seam allowance structure tire special for an electric automobile and a manufacturing method of the reinforced seam allowance structure tire. A reinforced seam allowance structure tire special for an electric automobile comprises a tread, a sidewall, a lining layer, a belted layer, a tire body and a seam allowance, the seam allowance is provided with a steel wire ring, upper apex and lower apex, and the tire body bypasses the steel wire ring and reversely wraps the outer side of the steel wire ring; the turn-up endpoint of the tire body is embedded between the upper apex and the lower apex, a steel ladle cord fabric is arranged on the outer side of the tire body at the turn-up position, the inner side endpoint of the steel ladle cord fabric is located above the steel wire ring, and the outer side endpoint of the steel ladle cord fabric is attached to the outer side of the upper apex. According to the tire, the turn-up endpoint of the tire body is embedded between the upper apex and the lower apex, so that the structure of early damage caused by excessive instant torque of a tire opening is reduced. Therefore, tire quality problems are reduced, and safety risks of electric vehicles are reduced.

    本发明涉及轮胎制造技术领域,尤其涉及一种电动汽车专用加强型子口结构轮胎及其制造方法。一种电动汽车专用加强型子口结构轮胎,该轮胎包括胎面、胎侧、内衬层、带束层、胎体和子口,所述子口设置有钢丝圈、上三角胶和下三角胶,胎体绕过钢丝圈反包在钢丝圈的外侧;胎体的反包端点嵌于上三角胶和下三角胶中间,并在反包位置的胎体外侧设置有钢包帘布,钢包帘布的内侧端点位于钢丝圈上方,外侧端点贴合设置在上三角胶的外侧。该轮胎通过将胎体的反包端点嵌于上三角胶和下三角胶中间,降低轮胎因子口瞬间扭力过大,导致早期损坏的结构。从而减少轮胎质量问题,降低电动车安全风险。
