The invention discloses a tire with an anti-torsion tire bead, and belongs to the field of tires. The problems that in the prior art, delamination is prone to occurring between a steel wire ring and a tire body cord thread, and delamination or cracking of rubber is prone to occurring at the bead heel position are solved. In the invention, one side of the tire body extends from the bottom of the steel wire ring to the outer side of the tire and forms the tire body turn-up part; one side of the steel wire seam allowance wrapping cloth extends from the bottom of the steel wire ring to the outer side of the tire to form a steel wire seam allowance wrapping cloth reverse wrapping part; an acute included angle is formed between the tire body and the tire body turn-up part; the steel wire ring comprises a plurality of steel wire layers, and each steel wire layer comprises a plurality of steel wires; in the radial direction of the steel wire ring, the number of the steel wires on the layer close to the inner side of the tire is a, the number of the steel wires on the layer with the largest width of the steel wire ring is b, and a is larger than or equal to 0.6 b and smaller than or equal to 0.75 b. According to the tire with the anti-torsion tire bead, the torsional rigidity of the tire bead part of the tire is improved, the torsional deformation of the tire bead part of the tire is reduced, and the problems of tire laddering burst and tire heel crack are solved.

    本申请公开了一种胎圈抗扭转轮胎,属于轮胎领域。解决了现有技术中钢丝圈和胎体帘线之间易产生脱层,胎踵位置易产生胶料的脱层或裂口的问题。本申请中,胎体的一侧经钢丝圈底部向轮胎外侧方向延伸并形成胎体反包部;钢丝子口包布的一侧经钢丝圈底部向轮胎外侧方向延伸并形成钢丝子口包布反包部;胎体与胎体反包部呈锐角夹角设置;钢丝圈包括若干层钢丝层,每层钢丝层包括若干根钢丝;在钢丝圈径向上,靠近轮胎内侧的一层钢丝根数为a,钢丝圈宽度最大的一层的钢丝根数为b,0.6b≤a≤0.75b。本申请的胎圈抗扭转轮胎,改善轮胎胎圈部的扭转刚性,减小轮胎胎圈部的扭转变形,改善轮胎抽丝爆和胎踵裂的问题。
