Automobile tire is a very important part of automobile, and it is the source of automobile movement. If a car's tire is broken, the car won't move. Therefore, we should pay attention to the maintenance of automobile tires. But sometimes there may be some very small holes in the car tire. Do you need to change the tire immediately? When the car tire which kind of time must change the tire, today small make up to give everybody to explain.

一、洞非常多

1、 There are many holes

当汽车轮胎出现比较小的口子时，很多司机都会送去4S店修补一下，修补完以后再继续用。如果出现一两个洞修补一下再继续用是没问题的，但是如果汽车轮胎上有三四个洞了，已经修补过很多次了，就必须要换了。即使这个轮胎暂时用起来没问题，但是在极限负载的情况下，这个轮胎的承受力会大不如前，很有可能会在半路上坏掉，所以必须尽快更换。

When there is a small hole in the tire, many drivers will send it to the 4S store to repair it, and then continue to use it. If one or two holes appear, it is OK to mend them, but if there are three or four holes in the tire that have been repaired many times, they must be replaced. Even if the tire is OK for the time being, under the condition of extreme load, the bearing capacity of the tire will not be as good as before. It is likely to break down on the way, so it must be replaced as soon as possible.

二、汽车轮胎鼓起来

2、 The car tires bulged

当汽车轮胎鼓起来的时候必须立马更换轮胎。如果汽车轮胎鼓起来还继续开车的话，汽车轮胎在行驶过程中会抖动的很厉害，甚有可能会爆胎，非常危险。汽车轮胎之所以会鼓起来一共有两个原因，个原因是轮胎在巨大的冲击力下导致变形严重，轮胎内部压力从而增大，这会造成轮胎胎侧帘子线断裂，从而形成鼓包。还有一个原因就是汽车轮胎本身质量不合格，所以才会引起鼓包

When a car tire bulges, it must be replaced immediately. If the car tires bulge up and continue to drive, the car tires will shake very much during the driving process, and even may burst, which is very dangerous. There are two reasons why the automobile tire bulges. The first reason is that the tire deforms seriously under the huge impact force, and the internal pressure of the tire increases, which will cause the tire sidewall cord to break and form the bulge. There is another reason is that the quality of the car tire itself is not up to standard, so it will cause bulging

三、花纹磨损严重

3、 The pattern is seriously worn

当汽车轮胎花纹磨损的非常严重时，必须马上更换轮胎。那么如何判断汽车轮胎花纹是不是磨损严重呢，其实汽车轮胎上面有一条条的凹槽，当凹槽和胎面一样平时，就说明汽车轮胎磨损非常严重，必须尽快换轮胎。还有当汽车轮胎裂纹非常多的时候，说明轮胎已经老化非常严重了，也必须立马更换轮胎。如果汽车轮胎里面嵌入了石子，大家不必惊慌，这是很正常的，只要把石子挑出来就可以了。如果不挑出来，可能会造成汽车轮胎的磨损。

When the tread pattern of automobile tire is worn seriously, the tire must be replaced immediately. So how to judge whether the tread pattern of an automobile tire is seriously worn? In fact, there are grooves on the tire surface. When the groove is the same as the tread, it means that the car tire is seriously worn and must be replaced as soon as possible. Also, when the car tire cracks are very much, it means that the tire has been aging very seriously, and the tire must be replaced immediately. If there are stones embedded in the car tires, we don't have to panic. This is very normal. Just pick out the stones. If you don't pick it out, it may cause tire wear.

四、使用时间已经有三到五年时

4、 It has been used for three to five years

汽车轮胎和人一样也是有寿命的，当汽车轮胎使用时间长达三五年时也必须要更换轮胎了，因为它的使用寿命已经到了，哪怕它还能用，但是它的承受能力也已经大不如前了。

Car tires, like people, also have a life span. When a car tire has been used for three to five years, it must be replaced because its service life has come. Even if it can still be used, its bearing capacity is not as good as before.

当汽车出现以上几种情况时，就需要及时更换轮胎，那么汽车轮胎平时保养的时候要注意些什么呢？要定期检查汽车轮胎胎压和磨损情况，如果胎压过高或者是过低都会加速汽车轮胎的磨损。

When the car appears the above several situations, it is necessary to replace the tire in time, so what should be paid attention to when maintaining the tire? First of all, we should regularly check the tire pressure and wear. If the tire pressure is too high or too low, it will accelerate the wear of the car tire.

如果汽车轮胎磨损情况严重是无法再使用的。其次要经常清理汽车轮胎内的杂物，比如石子玻璃什么的，如果不及时清理干净，会对轮胎造成很大的损伤。要及时补胎，如果汽车轮胎上面出现一些小口子一定要及时修补，如果口子比较大就要更换轮胎了。

If the car tire is seriously worn, it can not be used again. Secondly, we should often clean up the debris in the car tires, such as stone glass, if not cleaned up in time, it will cause great damage to the tires. Finally, the tire should be mended in time. If there are some small holes on the tire, it must be repaired in time. If the hole is large, the tire should be replaced.
