The invention discloses a ring-falling-preventing tire which comprises a tread, at least one full-covering or half-covering cap ply, at least one belted layer, at least one layer of forward-covering or reverse-covering tire body cord thread and a tire bead, the tire bead is provided with apex and a steel wire ring, and the tire body cord thread is arranged on the tire bead in a surrounding mode; and a seam allowance protection rubber and a lining layer are arranged on the outer side of the tire bead. The steel wire ring is of an asymmetrical special-shaped steel wire ring arrangement structure formed by winding a plurality of annular steel wires and/or a single steel wire. The ring-falling-preventing tire is simple in structure, adopts an asymmetric special-shaped steel wire ring structure, and can effectively prevent the tire from falling due to the fact that the base is wide and not prone to turnover. And the phenomenon that the ring falling test of the low-flatness-rate tire cannot be passed is reduced. And meanwhile, the size of the steel wire ring is limited, so that the tire can be mounted more easily.

    本发明公开了一种防脱圈轮胎,包括包括胎面、至少一层全覆盖或半覆盖冠带层,至少一层带束层,至少一层正包或反包的胎体帘线,以及胎圈,所述胎圈设置有三角胶和钢丝圈,所述胎体帘线环绕设置于所述胎圈;所述胎圈外侧设置有子口护胶,以及内衬层。所述钢丝圈采用多根环状钢丝和/或单钢丝缠绕的非对称异形钢丝圈排布结构。本发明结构简单,采用非对称异形的钢丝圈结构,因为底座宽,不容易发生翻转,可以有效防止轮胎脱圈。减少了低扁平率轮胎会出现脱圈试验不通过的现象。同时通过对钢丝圈的尺寸进行限定,从而达到在装胎时,能够更加容易。
