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?yàn)檩喬ナ钦婵蛰喬?，所以釘子不?huì)馬上漏出來，但是隨著時(shí)間的推移，空氣會(huì)慢慢漏出來。如果車主發(fā)現(xiàn)了輪胎釘，千萬不要粗心，應(yīng)到修理廠檢查。穿刺釘即使沒有滲漏也要及時(shí)維修，穿刺釘輪胎存在安全隱患，在高速行駛時(shí)也會(huì)容易穿刺。注意，未經(jīng)允許不得拉釘子，如拉出可能漏水，導(dǎo)致車輛無法行駛。這時(shí)，車主可以更換備用輪胎來修復(fù)輪胎;如果沒有漏氣，不要拔出釘子，慢慢開車到修理現(xiàn)場。

　　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.

　　問:一些車主問為什么他們的輪胎磨損得比別人快。開同樣的車，別人兩三年都不用換輪胎，但你只要開一年多，維修站建議馬上換輪胎?普通輪胎的使用壽命是多少?

　　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:輪胎壓力長期不正常，經(jīng)常行駛在較差的路面上，會(huì)導(dǎo)致輪胎磨損過快。普通汽車輪胎的使用壽命是6年，但由于輪胎行駛的公里數(shù)和路況不一樣，行駛的方式有差異，雖然同一輛車，輪胎的磨損程度肯定是不同的。如果輪胎磨損嚴(yán)重，就需要立即更換。

　　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.

　　在輪胎的側(cè)面，每隔30度就會(huì)有一個(gè)“△”的標(biāo)志，一個(gè)輪胎磨損的警示標(biāo)志。我國標(biāo)準(zhǔn)規(guī)定，轎車使用的子午線輪胎花紋磨損極限為1.6mm，卡車、客車使用的子午線輪胎花紋磨損極限為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.

　　沿三角標(biāo)志到輪胎表面，輪胎花紋磨損到底部1.6mm處的溝槽，此處的溝槽將開始斷裂，出現(xiàn)明顯裂紋。當(dāng)業(yè)主自己進(jìn)行檢查時(shí)，他可以與隨身攜帶的鑰匙進(jìn)行比較。如果槽的深度接近鍵的厚度，就有必要更換輪胎。

　　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.

　　問:過量添加再生橡膠對輪胎有什么影響?

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

　　答:如果在輪胎的制造過程中，加膠背的比例過高，輪胎就會(huì)“脆化”，使用壽命就會(huì)縮短，容易出現(xiàn)裂紋。

　　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.

　　問:輪胎的一些常見問題是什么?當(dāng)這些問題發(fā)生時(shí)，輪胎會(huì)發(fā)生什么變化?

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

　　更常見的是輪胎老化。隨著汽車數(shù)量的增多，輪胎利用率高，輪胎磨損嚴(yán)重，老化現(xiàn)象需要引起重視。

　　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，胎壓異常，胎面壓力不足時(shí)，胎面兩側(cè)會(huì)出現(xiàn)過度磨損。當(dāng)氣壓過高時(shí)，位置的胎面會(huì)被過度磨損，開車時(shí)會(huì)有“跳”跳的感覺，同時(shí)，輪胎的抓地力也會(huì)降低，油耗會(huì)增加，剎車性能會(huì)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，備胎要隨車帶出外層保護(hù)層，輪胎暴露在空氣中，半年就會(huì)硫化，輪胎變得“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".

　　問:實(shí)習(xí)司機(jī)女士問:“如果我開車的時(shí)候爆胎了，我該怎么辦?”

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

　　A:如果開車時(shí)爆胎了，不要猛踩剎車。輪胎爆胎時(shí)，身體處于不平衡狀態(tài)。當(dāng)你猛踩剎車時(shí)，汽車很容易打滑。當(dāng)你的輪胎漏氣時(shí)，你應(yīng)該緊緊抓住方向盤，保持車輛的方向，不斷地踩剎車減速，然后滑行到路邊。

　　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，滑到匝道并停車，打開你的危險(xiǎn)燈并盡快離開高速公路。

　　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.
