The invention discloses a run-flat tire, the thicknesses of rubber between a main groove and a belt part are set to be unequal, the belt part is composed of a steel wire annular belt part and a bulge-resistant annular belt part, the steel wire annular belt part is set to be high in rigidity, and the bulge-resistant annular belt part is set to be large in tension; the tensions of different parts of the bulge-resistant annular belt part are set to be unequal, and the area of the pattern blocks at the shoulder part of the tread is set to be larger than that of the pattern blocks at the middle part of the tread. The run-flat tire can keep a larger ground contact area under the condition of low pressure, so that the run-flat tire also has better ground holding performance under the condition of low pressure.

    本发明公开了一种缺气保用轮胎,该缺气保用轮胎将主沟与带束部之间的橡胶厚度设置为不等,采用钢丝环带部和耐隆环带部组成带束部,并将钢丝环带部设置为高刚度,将耐隆环带部设置为大张力,还将耐隆环带部不同部位的张力设置为不等,还将胎面肩部的花纹块的面积设置得大于胎面中部的花纹块面积。该缺气保用轮胎在低压情况下也能保持较大的接地面积,因而在低气压情况下也具有较好的抓地性能。
