The invention discloses a supporting type run-flat tire, which belongs to the technical field of tires, and comprises an airtight layer and a cord fabric layer, wherein the outer side of the airtight layer and the inner side of the cord fabric layer are attached to a tread, supporting rubber is laid on the outer side of the airtight layer and on a tire side and a tire shoulder, and the inner side of the cord fabric layer is attached to the outer surface of the supporting rubber on the tire side and the tire shoulder. The radial section of the supporting rubber is in a crescent shape. The supporting rubber is arranged between the airtight layer and the cord fabric layer and located on the tire side wall and the tire shoulder, the tire is effectively supported, the supporting performance of the tire in the low-pressure or zero-pressure state caused by air leakage or tire burst is effectively improved, the radial section of the tire is further arranged to be in a crescent shape, the mechanical property of the tire is optimized, the tire shoulder and the tire side wall of the tire are effectively reinforced, and the overall deflection and the load of the tire are increased.

    本申请公开了一种支撑式缺气保用轮胎,属于轮胎技术领域,包括气密层和帘布层,气密层外侧与帘布层内侧位于胎面处贴合,气密层外侧位于胎侧及胎肩处铺设有支撑胶,帘布层内侧位于胎侧及胎肩处与支撑胶外表面贴合,支撑胶沿径向的截面呈月牙形。其通过在气密层与帘布层之间位于胎侧和胎肩处设置支撑胶,对轮胎进行有效支撑,有效提升其漏气或爆胎导致的低气压或0气压状态时的支撑性能,进一步通过设置其径向截面呈月牙形,优化其力学性能,有效对轮胎的胎肩和胎侧进行强化,增加轮胎的整体挠度和载荷。
