1、轮胎气压过低。当轮胎气压过低时,轮胎径向变形增大,胎肩将发生过度挠曲,促使胎肩与地面接触面积增大,滚动阻力增加,胎面磨损不均,磨擦产生高热,降低了橡胶的抗拉强度,造成帘线松散而脱层。同时,碰到障碍物时,胎体内层容易产生帘线断裂,以致爆破。

1, the tire pressure is too low. When the tire pressure is too low, the radial deformation of the tire increases, the shoulder will be excessive deflection, to promote increased contact area between the shoulder and the ground, increasing rolling resistance, tread wear uneven, friction heat, reducing the rubber Tensile strength, resulting in loose cords and delamination. At the same time, encounter obstacles, the inner carcass prone to cord breakage, resulting in blasting.
