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!

轮胎鼓包的原因，主要分成以下三点!

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

1.制造原因：胎体帘布帘线、密度疏忽不均，胎侧帘线搭接不良

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

2.安装原因：胎面底部帘线被划伤。

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

3.使用原因：擦伤、撞伤、刺伤垫伤及划伤。

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

如果你的轮胎出现鼓包了，一定要看看是因为什么鼓包的，我们一起看看轮胎鼓包的鉴别方法。

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.

鼓包鉴别方法

Bulge identification method

轮胎起鼓是很常见的，有经验的师傅不需要借助设备，通过眼观手摸既可以实施准确的鉴定。

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

鉴别轮胎鼓包的主要是看轮胎起鼓内外侧有无伤痕：

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

1.如果内侧有伤痕，再看看一下轮胎起鼓的部位，有胎圈底部帘线划伤，这是因为轮胎安装不良导致的轮胎鼓包。

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.

如果轮胎内外侧有伤痕，并且有外伤、帘线断裂、胎里凹痕，这样的轮胎鼓包是因为车主使用不当造成的。

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.如果轮胎内外侧没有伤痕，这样的情况下，车主可以把轮胎沿周向等半径，手用里顶住胎体左右移动，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.

操作完毕，如果感觉到轮胎鼓包的厚度略薄或者强度稍弱，这样的轮胎鼓包是因为制作不良。如果感觉到轮胎鼓包的地方，强度没有明显的差异，这样的轮胎鼓包，就是胎体帘线遭撞击后，发生的变形。

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.

大家都可以自己去鉴别自己的轮胎是因为什么鼓包的了，如果是因为人为导致轮胎鼓包，商家是不会理赔的。

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.
