The invention relates to the technical field of automobile tires, and particularly discloses a spare tire, which is used for solving the problem of insufficient safety of a spare tire in the prior art. Comprising two steel wire rings, the outer sides of the steel wire rings are wrapped with supporting apex, a sidewall is distributed on the outer side of the supporting apex, a polyester tire body layer is arranged between the supporting apex and the sidewall, a lining layer is arranged on the inner side of the supporting apex where the polyester tire body layer is located, two steel wire belt plies are arranged at the upper end of the lining layer, and tread layers are arranged on the outer sides of the steel wire belt plies. The tire further comprises a pattern structure arranged on the tread layer. By optimizing the tread pattern design, the control stability of the tire in the running process is improved, and the braking distance is reduced; by optimizing the contour and structural design of the tire, the tire stress in the driving process is improved, the tire wear is delayed, the effective driving time of the tire is prolonged, and the driving safety is ensured.

    本发明涉及汽车轮胎技术领域,具体公开了一种备用轮胎,用以解决现有技术中备胎安全性不足的问题;包括两个钢丝圈,所述钢丝圈外侧包裹有支撑三角胶,胎侧分布在支撑三角胶外侧,支撑三角胶和胎侧之间设有一层聚酯胎体层,聚酯胎体层所在的支撑三角胶内侧设有内衬层,内衬层上端设有两层钢丝带束层,钢丝带束层外侧设有胎面层;还包括设置在胎面层的花纹结构。本发明通过优化胎面花纹设计,提升轮胎行驶过程中的操控稳定性,减少制动距离;通过优化轮胎轮廓及结构设计,改善行驶过程中轮胎受力,延缓轮胎磨损,提升轮胎有效行驶时间,确保行驶安全。
