问：很多轮胎磨损和磨损都没有

问候，感谢您写这个问题！我们首先需要将“车轮”和“轮胎”分开。车轮是轮胎（黑色橡胶）安装的金属（铝或钢）。轮胎通常应持续超过30,000英里。但是，轮胎寿命取决于许多原因：车辆负载，驾驶速度，温度和通胀压力。旋转轮胎并正确设置轮胎压力是提高轮胎寿命的最佳方法。轮胎穿着均匀吗？如果边缘均匀地穿着，但中心却没有，则轮胎充气不足。如果轮胎的中心穿着，但边缘没有，那么轮胎会被膨胀。如果轮胎的内边缘被“羽毛”或过早佩戴，则存在悬架或对齐问题。 Next time you’re searching for tires, be sure to use the Uniform Tire Quality Grading guidelines to choose a proper tire. The “treadwear grade” gives a good indication of how long a tire will last. A tire rated at “400” should last twice as long as a tire rated at “200.” However, manufacturers use different standards for the treadwear ratings. In general, the higher the number, the longer the tire will last. An expert mechanic, such as YourMechanic, can perform a轮胎检查并提供暗示的行动。
