背景技术Background technique
一般来说正常使用的轮胎寿命是4到5年，过了5年即使胎纹的磨损很小也最好换掉，因为胎面的橡胶会因时间久远而发生老化，而许多细小的裂纹正是造成爆胎的诱因。不过国家相关部门暂时还没有对轮胎的保质期作出专门规定，因为根据轮胎橡胶配方的不同、用车环境和驾驶习惯的不同，轮胎的使用寿命也会各不相同。所以这就需要我们平时开车多留些心，轮胎老化也是有征兆的。比如胎面老化的部位大都是从胎边或胎肩等边缘部位开始出现的，长期的日晒雨淋会让橡胶表面出现成圈的小裂纹，这些裂纹表明此时轮胎的承载力和品质都已经开始下降了，为了降低爆胎风险最好提前更换。Generally speaking, the service life of tires in normal use is 4 to 5 years. After 5 years, even if the wear of the tread pattern is small, it is best to replace it, because the rubber of the tread will age over time, and many small cracks are on the way. is the cause of a blowout. However, the relevant state departments have not yet made special regulations on the shelf life of tires, because the service life of tires will vary depending on the tire rubber formula, vehicle environment and driving habits. So this requires us to pay more attention when driving, and there are signs of tire aging. For example, most of the aging parts of the tread appear from the edge of the bead or shoulder. Long-term exposure to the sun and rain will cause small cracks in circles on the rubber surface. These cracks indicate that the bearing capacity and quality of the tire at this time are not good. It has already begun to decline. In order to reduce the risk of puncture, it is best to replace it in advance.
但是一般汽车驾驶员都很少定期对车胎进行检测，使得汽车行驶存在安全隐患。But general car driver all seldom detects regularly to car tire, makes the automobile driving to have potential safety hazard.
