汽车的轮胎,包括备用轮胎,一定要每月定期检查。检查时要观察轮胎表面是否有裂痕或划伤。最好戴上手套伸到轮胎内侧,检查是否有可疑的痕迹。只要发现有丝毫可疑之点,要立即到修理厂做详细检查。有毛病的轮胎不要舍不得换。假如发现轮胎表面磨损情况不正常,应想到可能车轮的前束调校有问题,要及时修理。 Car tires, including spare tires, must be regularly checked monthly. Check the tire surface to observe whether there are cracks or scratches. It is best to wear gloves to the inside of the tire and check for signs of doubt. As long as you find the slightest point of doubt, to the repair shop to do a detailed inspection. Faulty tires do not want to change. If you find that the surface of the tire wear and tear is not normal, should think of the wheel may be a problem before the beam adjustment, to be promptly repaired.
