Prick a hole

您的爱车被扎过轮胎吗?如果有那么是多长时间前的事了呢?其实对于已经补了很长时间的轮胎来说，即使暂时用起来没问题，但在负载下的承受力也会大不.如从前;另外，同一条轮胎上如果已经扎了3个以上的洞，我们还是建议您尽快把它换掉。

Has your car ever had a puncture? If so, how long ago was it? In fact, for tires that have been mended for a long time, even if it's OK to use temporarily, the bearing capacity under load will be very different As before; In addition, if more than 3 holes have been pierced in the same tire, we still suggest you replace it as soon as possible.

鼓包

swelling

汽车如果以高速驶过凹坑、障碍物及马路牙子时，轮胎局部在大的撞.击力下将发生严重变形，从而内.部压力瞬.间.增.大，这样的直接后果就是造成胎侧帘子线断裂而引起鼓包。另外在相同冲击力度下，低扁平比的轮胎比高扁平比轮胎容易造成胎侧鼓包。已经发生了鼓包的轮胎须.立.即换，否则就有爆胎的隐患。

If the car passes through pits, obstacles and Road teeth at high speed, the tire will be hit locally Severe deformation will occur under the impact force, resulting in internal deformation The pressure in the upper part is instantaneous Room Increase The direct consequence of this is that the sidewall cord is broken and bulging is caused. In addition, under the same impact force, the tire with low flat ratio is easier to cause sidewall bulge than the tire with high flat ratio. A bulging tyre whisker has occurred stand. Replace it immediately, otherwise there will be a hidden danger of tire burst.

花纹

decorative pattern

一.般.来.说，正常使用的家用轿车可以每6万或两年换一.次轮胎，但对于花纹磨损严重的轮胎则应提早换。现在的快修店都有花纹磨损标尺，车主可以买一把，随.时检测自己轮胎的花纹磨损状况。此外，胎面裂纹增多也是老化严重的.象.征，平时可以适当喷一些轮胎保护蜡，还有就是开车时尽量不要压到腐蚀性的液体。

I General Come on He said that family cars in normal use can be replaced every 60000 kilometers or two years Secondary tires, but tires with serious pattern wear should be replaced in advance. At present, all express repair shops have pattern wear scales. Car owners can buy one and follow Check the pattern wear condition of your own tires when. In addition, the increase of tread cracks is also a serious cause of aging Elephant Sign, you can spray some tire protection wax properly at ordinary times, and try not to press corrosive liquid when driving.

气压

pressure

现在的大多数家用轿车都使用了无内胎的子午线轮胎，对于前驱车来说由于发动机、变速箱等重要驱动部件都压在前部，所以前轮有时看起来会有点瘪，但目测是不准确的，一.定要用专.用的胎压表测量。一.般.来.说前轮的气压在2.0帕—2.2帕之间，(由于每辆车的用途和设计各有不同，所以好参考使用说明书上标定的厂方数值)，夏天可以适当低一些。

Nowadays, most family cars use tubeless radial tires. For front drive vehicles, the front wheels sometimes look a little deflated because the engine, gearbox and other important driving parts are pressed in the front, but the visual inspection is inaccurate Be sure to use special tools Measure with a tire pressure gauge. I General Come on It is said that the air pressure of the front wheel is between 2.0 PA and 2.2 Pa. (since the purpose and design of each vehicle are different, it is good to refer to the manufacturer's value calibrated in the operation manual). It can be lower in summer.

石子

gravel

有些车主经常会听见自己的爱车在行驶时会发出声音，但车用起来却也没有故障，这时您就要检查一下是不是有小石子卡在轮胎花纹里了。其实只要平时抽空用钥匙将胎面纹路里的这些小石粒挖出来，会使轮胎的制动抓地稳定，而且还避.免了胎噪。

Some car owners often hear that their car will make a sound when driving, but the car has no fault when using. At this time, you need to check whether there are small stones stuck in the tire pattern. In fact, as long as you take the time to dig out these small stones in the tread pattern with the key, the braking and grip of the tire will be stable and the tire can be avoided Avoid tire noise.

备胎

spare tire

要想备胎起到真.正应急的作用，平时就要重视对其的保养。要经常检查备胎气压;其次，备胎要注意防油蚀，备胎是橡胶制品，怕各.种油品的侵蚀。轮胎沾油后，很快就会发生胀蚀，这会大大降.低备胎的使用寿命。备胎的寿命在4年左右，很多车主错误地认为备胎不用就一直是新的，其实过了4年即使备胎一.次也没有使用过也要换，否则备胎就成了废胎。

If you want the spare tire to work really well It is the role of emergency, and we should pay attention to its maintenance at ordinary times. Always check the spare tire pressure; Secondly, the spare tire should pay attention to oil corrosion prevention. The spare tire is made of rubber, which is afraid of various Erosion of oil products. After the tire is stained with oil, it will swell and corrode soon, which will greatly reduce the pressure Low service life of spare wheel. The service life of the spare tire is about four years. Many car owners mistakenly believe that the spare tire is always new when it is not used. In fact, after four years, even if the spare tire is one If you haven't used it twice, you should also replace it, otherwise the spare tire will become a waste tire.
