Q: a car owner asked - there is a nail in the tire during driving. It has been several days and there is no air leak in the tire. Is there no need to deal with it?

　　因为轮胎是真空轮胎，所以钉子不会马上漏出来，但是随着时间的推移，空气会慢慢漏出来。如果车主发现了轮胎钉，千万不要粗心，应到修理厂检查。穿刺钉即使没有渗漏也要及时维修，穿刺钉轮胎存在隐患，在高速行驶时也会容易穿刺。注意，未经允许不得拉钉子，如拉出可能漏水，导致车辆无法行驶。这时，车主可以更换备用轮胎来修复轮胎;如果没有漏气，不要拔出钉子，慢慢开车到修理现场。

　　Because the tire is a vacuum tire, the nail will not leak out immediately, but as time goes on, the air will leak out slowly. If the car owner finds the tyre studs, don't be careless and check them in the repair shop. Even if there is no leakage, the puncture pin should be repaired in time. The puncture pin tire has potential safety hazards and is easy to puncture when driving at high speed. Note that nails shall not be pulled without permission. If pulled out, water may leak, causing the vehicle to be unable to drive. At this time, the owner can replace the spare tire to repair the tire; if there is no air leakage, do not pull out the nail, and slowly drive to the repair site.

　　问:一些车主问为什么他们的轮胎磨损得比别人快。开同样的车，别人两三年都不用换轮胎，但你只要开一年多，维修站建议马上换轮胎?普通轮胎的使用寿命是多少?

　　Q: some car owners ask why their tires wear faster than others. Driving the same car, others don't need to change tires for two or three years, but you only need to drive for more than one year, the maintenance station suggests changing tires immediately? What is the service life of ordinary tires?

　　A:轮胎压力长期不正常，经常行驶在较差的路面上，会导致轮胎磨损过快。普通汽车轮胎的使用寿命是6年，但由于轮胎行驶的数和路况不一样，行驶的方式有差异，虽然同一辆车，轮胎的磨损程度肯定是不同的。如果轮胎磨损严重，就需要立即更换。

　　A: The tire pressure is abnormal for a long time, and often driving on a poor road surface will cause the tire to wear too fast. The service life of ordinary car tires is 6 years, but because of the different mileage and road conditions, the driving mode is different. Although the same car, the wear degree of tires is certainly different. If the tires are badly worn, they need to be replaced immediately.

　　在轮胎的侧面，每隔30度就会有一个“△”的标志，一个轮胎磨损的警示标志。我国标准规定，轿车使用的子午线轮胎花纹磨损极限为1.6mm，卡车、客车使用的子午线轮胎花纹磨损极限为2.0mm。

　　On the side of the tire, there will be a "△" sign and a warning sign of tire wear every 30 degrees. According to China's standard, the wear limit of radial tire pattern used in cars is 1.6mm, and that used in trucks and buses is 2.0mm.

　　沿三角标志到轮胎表面，轮胎花纹磨损到底部1.6mm处的沟槽，此处的沟槽将开始断裂，出现明显裂纹。当业主自己进行检查时，他可以与随身携带的钥匙进行比较。如果槽的深度接近键的厚度，就有必要更换轮胎。

　　Along the triangle mark to the tire surface, the tread pattern of the tire is worn to the groove at the bottom 1.6mm, where the groove will start to break and obvious cracks will appear. When the owner checks himself, he can compare it with the key he carries with him. If the depth of the groove is close to the thickness of the key, it is necessary to replace the tire.

　　问:过量添加再生橡胶对轮胎有什么影响?

　　Q: what is the effect of excessive addition of recycled rubber on tires?

　　答:如果在轮胎的制造过程中，加胶背的比例过高，轮胎就会“脆化”，使用寿命就会缩短，容易出现裂纹。

　　A: if the proportion of rubber back is too high in the manufacturing process of tire, the tire will be "brittle", the service life will be shortened, and cracks will easily appear.

　　问:轮胎的一些常见问题是什么?当这些问题发生时，轮胎会发生什么变化?

　　Q: what are some common problems with tyres? When these problems occur, what will happen to tyres?

　　更常见的是轮胎老化。随着汽车数量的增多，轮胎利用率高，轮胎磨损严重，老化现象需要引起重视。

　　The most common is tire aging. With the increase of the number of cars, the utilization rate of tires is high, the tires are worn seriously, and the aging phenomenon needs to be paid attention to.

　　其次，胎压异常，胎面压力不足时，胎面两侧会出现过度磨损。当气压过高时，位置的胎面会被过度磨损，开车时会有“跳”跳的感觉，同时，轮胎的抓地力也会降低，油耗会增加，刹车性能会降低。

　　Secondly, when the tire pressure is abnormal and the tire tread pressure is insufficient, excessive wear will occur on both sides of the tire tread. When the air pressure is too high, the tread in the center position will be excessively worn, and there will be the feeling of "jumping" when driving. At the same time, the grip of the tire will be reduced, the fuel consumption will be increased, and the braking performance will be reduced.

　　此外，备胎要随车带出外层保护层，轮胎暴露在空气中，半年就会硫化，轮胎变得“脆嫩”。

　　In addition, the spare tire should take out the outer protective layer with the car. When the tire is exposed to the air, it will be vulcanized in half a year and become "crisp and tender".

　　问:实习司机女士问:“如果我开车的时候爆胎了，我该怎么办?”

　　Q: Ms. Wang, the trainee driver, asked, "what should I do if I have a flat tire while driving?"

　　A:如果开车时爆胎了，不要猛踩刹车。轮胎爆胎时，身体处于不平衡状态。当你猛踩刹车时，汽车很容易打滑。当你的轮胎漏气时，你应该紧紧抓住方向盘，保持车辆的方向，不断地踩刹车减速，然后滑行到路边。

　　A: If you have a flat tire while driving, don't slam on the brake. When the tire blows out, the body is in an unbalanced state. When you slam on the brakes, the car slips easily. When you have a flat tire, you should hold on to the steering wheel, keep the vehicle in the direction, step on the brake constantly to slow down, and then slide to the side of the road.

　　如果你在高速公路上爆胎了，滑到匝道并停车，打开你的危险灯并尽快离开高速公路。

　　If you have a flat tire on the highway, slide to the ramp and stop, turn on your hazard lights and leave the highway as soon as possible.
