A pneumatic tire unsupported by an inner tube or a sidewall, wherein a wear-resistant layer or a wear-resistant lubrication layer (133; 233; 333) is disposed at an inner surface rubber layer of a tire outer side (20), or disposed at an inner surface rubber layer of the tire outer side (20) and a tire inner side (21). The wear-resistant layer (133; 233; 333) is located at at least one of the following three portions: a tire bead (100), a tire sidewall (200), and a tire shoulder (300). After the tire, which is a zero-pressure tire, goes flat, two surfaces of the inner surface rubber layer come into contact with each other, wherein the wear-resistant layer (133; 233; 333) provided at the contact position can improve wear resistance and increase tire mileage and speed limitations. Further, the wear-resistant lubrication layer (133; 233; 333) provided at the contact position can decrease friction coefficients of a contact surface to reduce friction, and reduce the risk of tire bead unseating. The reduction of friction can improve wear resistance and tire mileage, and can also reduce tire rolling resistance, prevent an unbalanced exertion of force at two sides of the wheels, and improve vehicle controllability.

    一种无内胎无侧壁支撑的充气轮胎,在轮胎外侧(20),或者在轮胎外侧(20)和轮胎内侧(21)的轮胎内表面橡胶层上设置耐磨层或耐磨润滑层(133;233;333),所述耐磨层(133;233;333)位于胎圈(100)、胎侧(200)、胎肩(300)三个部位中的至少一个部位。0气压轮胎被压扁后,轮胎内表面橡胶层两内表面接触:接触位置设置耐磨层(133;233;333)可提高耐磨性,增加轮胎行驶里程和行驶速度;接触位置设置耐磨润滑层(133;233;333)可减少接触面的摩擦系数降低摩擦力,降低轮胎脱圈风险,摩擦力降低可提高耐磨性,增加轮胎行驶的里程;摩擦力降低可减少轮胎的滚动阻力,减小两侧车轮受力不平衡状况,提高车辆的操控性。
