When it comes to tire bulging, this is also a common problem of tires. It is difficult to explain. Some car owners respond to the car maintenance master. Why do tires always have bulging problems? This problem not only puzzles the car owner, but also puzzles the tire owner. I don't know if you have studied this problem. Today, I'll discuss this problem with Jinan BMW master!

輪胎鼓包的原因，主要分成以下三點(diǎn)!

The causes of tire bulge are mainly divided into the following three points!

1.制造原因：胎體簾布簾線、密度疏忽不均，胎側(cè)簾線搭接不良

1. Manufacturing reasons: the density of carcass cord cloth and cord is negligent and uneven, and the overlapping of sidewall cord is poor

2.安裝原因：胎面底部簾線被劃傷。

2. Installation reason: the cord at the bottom of tread is scratched.

3.使用原因：擦傷、撞傷、刺傷墊傷及劃傷。

3. Use reason: scratch, bump, stab pad and scratch.

如果你的輪胎出現(xiàn)鼓包了，一定要看看是因?yàn)槭裁垂陌?，我們一起看看輪胎鼓包的鑒別方法。

If your tire has a bulge, be sure to see what the bulge is. Let's take a look at the identification method of tire bulge.

鼓包鑒別方法

Bulge identification method

輪胎起鼓是很常見(jiàn)的，有經(jīng)驗(yàn)的師傅不需要借助設(shè)備，通過(guò)眼觀手摸既可以實(shí)施準(zhǔn)確的鑒定。

Tire bulging is very common. Experienced masters can carry out accurate identification through eye observation and hand touch without the help of equipment.

鑒別輪胎鼓包的主要是看輪胎起鼓內(nèi)外側(cè)有無(wú)傷痕：

The main to identify tire bulge is to see whether there are scars on the inner and outer sides of tire bulge:

1.如果內(nèi)側(cè)有傷痕，再看看一下輪胎起鼓的部位，有胎圈底部簾線劃傷，這是因?yàn)檩喬グ惭b不良導(dǎo)致的輪胎鼓包。

1. If there are scars on the inner side, look at the bulging part of the tire. There is a scratch on the cord at the bottom of the bead, which is due to the bulging of the tire caused by poor tire installation.

如果輪胎內(nèi)外側(cè)有傷痕，并且有外傷、簾線斷裂、胎里凹痕，這樣的輪胎鼓包是因?yàn)檐?chē)主使用不當(dāng)造成的。

If there are scars on the inner and outer sides of the tire, trauma, cord fracture and dent in the tire, such tire bulge is caused by improper use by the owner.

2.如果輪胎內(nèi)外側(cè)沒(méi)有傷痕，這樣的情況下，車(chē)主可以把輪胎沿周向等半徑，手用里頂住胎體左右移動(dòng)，例如如下操作。

2. If there are no scars on the inner and outer sides of the tire, in this case, the owner can push the tire with equal radius in the circumferential direction and press the tire body with his hand to move left and right, such as the following operations.

操作完畢，如果感覺(jué)到輪胎鼓包的厚度略薄或者強(qiáng)度稍弱，這樣的輪胎鼓包是因?yàn)橹谱鞑涣肌Ｈ绻杏X(jué)到輪胎鼓包的地方，強(qiáng)度沒(méi)有明顯的差異，這樣的輪胎鼓包，就是胎體簾線遭撞擊后，發(fā)生的變形。

After operation, if you feel that the thickness of the tire bulge is slightly thin or the strength is slightly weak, such tire bulge is due to poor production. If there is no obvious difference in strength at the place where the tire bulge is felt, such a tire bulge is the permanent deformation after the tire cord is impacted.

大家都可以自己去鑒別自己的輪胎是因?yàn)槭裁垂陌牧?，如果是因?yàn)槿藶閷?dǎo)致輪胎鼓包，商家是不會(huì)理賠的。

Everyone can identify their own tires because of the bulge. If it is caused by man-made tires, the merchant will not settle the claim.
