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

當汽車輪胎出現比較小的口子時，很多司機都會送去4S店修補一下，修補完以后再繼續用。如果出現一兩個洞修補一下再繼續用是沒問題的，但是如果汽車輪胎上有三四個洞了，已經修補過很多次了，就必須要換了。即使這個輪胎暫時用起來沒問題，但是在極限負載的情況下，這個輪胎的承受力會大不如前，很有可能會在半路上壞掉，所以必須盡快更換。

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、汽車輪胎鼓起來

2、 The car tires bulged

當汽車輪胎鼓起來的時候必須立馬更換輪胎。如果汽車輪胎鼓起來還繼續開車的話，汽車輪胎在行駛過程中會抖動的很厲害，甚至有可能會爆胎，非常危險。汽車輪胎之所以會鼓起來一共有兩個原因，個原因是輪胎在巨大的沖擊力下導致變形嚴重，輪胎內部壓力從而增大，這會造成輪胎胎側簾子線斷裂，從而形成鼓包。還有一個原因就是汽車輪胎本身質量不合格，所以才會引起鼓包

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、花紋磨損嚴重

3、 The pattern is seriously worn

當汽車輪胎花紋磨損的非常嚴重時，必須馬上更換輪胎。那么如何判斷汽車輪胎花紋是不是磨損嚴重呢，其實汽車輪胎上面有一條條的凹槽，當凹槽和胎面一樣平時，就說明汽車輪胎磨損非常嚴重，必須盡快換輪胎。還有當汽車輪胎裂紋非常多的時候，說明輪胎已經老化非常嚴重了，也必須立馬更換輪胎。如果汽車輪胎里面嵌入了石子，大家不必驚慌，這是很正常的，只要把石子挑出來就可以了。如果不挑出來，可能會造成汽車輪胎的磨損。

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、使用時間已經有三到五年時

4、 It has been used for three to five years

汽車輪胎和人一樣也是有壽命的，當汽車輪胎使用時間長達三至五年時也必須要更換輪胎了，因為它的使用壽命已經到了，哪怕它還能用，但是它的承受能力也已經大不如前了。

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.

當汽車出現以上幾種情況時，就需要及時更換輪胎，那么汽車輪胎平時保養的時候要注意些什么呢？首先要定期檢查汽車輪胎胎壓和磨損情況，如果胎壓過高或者是過低都會加速汽車輪胎的磨損。

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.

如果汽車輪胎磨損情況嚴重是無法再使用的。其次要經常清理汽車輪胎內的雜物，比如石子玻璃什么的，如果不及時清理干凈，會對輪胎造成很大的損傷。要及時補胎，如果汽車輪胎上面出現一些小口子一定要及時修補，如果口子比較大就要更換輪胎了。

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.
