The invention relates to the field of tires, in particular to a tire with a spirally wound belted layer structure at a shoulder part. The tire with the spirally wound belted layer structure at a shoulder part comprises a tread, a belt ply component and a carcass ply, the belt ply component is located between the tread and the carcass ply, the belt ply component is integrally attached to the carcass ply, and the belt ply component comprises a first belt ply, a second belt ply, a third belt ply and a fourth belt ply which are sequentially attached from bottom to top. The tire further comprises afifth belt ply, the fifth belt ply and the fourth belt ply are located on the same layer, the fifth belt ply is circumferentially and spirally wound at the two ends of the fourth belt ply and locatedabove the third belt ply, and the sum of the width of the fourth belt ply and the width of the fifth belt ply is smaller than the width of the third belt ply. Compared with the prior art, shoulder deformation caused by a 0-degree belted layer structure in the prior art is avoided, the grounding pressure distribution uniformity and the grounding performance of the tire are improved, the durabilityof the tire is improved, and the service life of the tire is prolonged.

    本发明涉及轮胎领域,具体涉及一种肩部采用螺旋缠绕带束层结构的轮胎。一种肩部采用螺旋缠绕带束层结构的轮胎,包含胎面、带束层构件、胎体帘布,所述带束层构件位于胎面和胎体帘布之间,所述带束层构件整体贴合在胎体帘布上,所述带束层构件包含自下而上依次贴合的1#带束层、2#带束层、3#带束层、4#带束层,还包含5#带束层,所述5#带束层与4#带束层位于同一层,且5#带束层周向螺旋缠绕在4#带束层两端,且位于3#带束层上方,所述4#带束层宽度与5#带束层宽度之和窄于3#带束层的宽度。与现有技术相比,避免了现有技术中的0°带束层结构带来的肩部变形,提高了轮胎的接地压力分布均匀性和接地性能,提高了轮胎的耐久性能和使用寿命。
