“啃胎”就是指一个或几个车轮胎发生不正常的快速磨损，那么，车友们所言的“啃胎”究竟有哪几种磨损类型?下面
济南沃尔沃汽车养护人员为您讲解：
'Tire gnawing' refers to the abnormal rapid wear and tear of one or several car tires. So, what are the types of wear and tear that car enthusiasts refer to as' tire gnawing '? Below, the maintenance personnel of Jinan Volvo Cars will explain to you:
1
one
轮胎磨耗
Tire center wear
轮胎磨耗严重通常是由于气压过高，胎面需要承受车辆的载重，增加了胎面的摩擦。车辆会跳动，舒适性也会降低。
Severe wear at the center of a tire is usually due to excessive air pressure, which requires the center of the tire to withstand the load of the vehicle, increasing friction at the center of the tire. The vehicle will jump and its comfort will also decrease.

two
双侧胎肩磨耗
Bilateral shoulder wear
轮胎气压不足，两侧胎肩就会凸起，从而造成磨损过快，而且胎压不足会引起油耗增大，还会造成轮胎缺气被碾压损毁。
If the tire pressure is insufficient, the shoulders on both sides of the tire will protrude, causing rapid wear. Moreover, insufficient tire pressure can cause increased fuel consumption and even cause tire deflation and damage due to crushing.

three
单边磨耗
Unilateral wear
高速转弯时由于惯性力和离心力的作用，使车内货物倾斜一侧，造成单边轮胎超载拖曳，加速轮胎磨损。
When turning at high speeds, due to the inertia and centrifugal forces, the cargo inside the vehicle tilts to one side, causing overloading and dragging of one side tires, accelerating tire wear.

four
花纹呈锯齿状磨损
The pattern shows serrated wear
锯齿状磨损主要是因为前轮定位调整不当或前悬挂系统位置失常、球头松旷等，使正常滚动的车轮发生滑动或行驶中车轮定位不断变动而形成。
Sawtooth wear is mainly caused by improper adjustment of the front wheel alignment, abnormal position of the front suspension system, loose ball joints, etc., causing normal rolling wheels to slip or constantly changing wheel alignment during driving.
5
five
胎面花纹的局部磨损
Local wear of tread patterns
很明显是由于紧急制动使车轮抱死，或者快速起步使车轮打滑引起的胎面局部磨损，应该尽量避免紧急制动与急速起动。
It is obvious that emergency braking causes the wheels to lock up, or rapid starting causes the wheels to slip and cause local wear on the tread. It is advisable to avoid emergency braking and rapid starting as much as possible.
如何避免：
How to avoid:
1、至少每个月检查一次车上所有轮胎在冷却情况下的气压，胎压过低或过高，胎面磨损都会加快，好根据汽车车门下角的规定胎压进行充气。
1. At least once a month, check the air pressure of all tires on the vehicle under cooling conditions. If the tire pressure is too low or too high, the tire tread wear will accelerate, so as to inflate according to the specified tire pressure in the lower corner of the car door.
2、感觉轮胎有摆动，要及时进行轮胎动平衡检测，如果不平衡要加装平衡铅块保持平衡，以免发生“啃胎”现象。
2. If the tire feels swaying, it is necessary to conduct a dynamic balance test on the tire in a timely manner. If it is imbalanced, a balance lead block should be installed to maintain balance to avoid the phenomenon of "gnawing the tire".
3、时常检查轮胎是否有鼓包、裂缝、割伤、扎钉和不正常的磨耗。等等。
3. Regularly check the tires for bulges, cracks, cuts, punctures, and abnormal wear. Wait a minute.
In fact, besides the quality issues of the car itself, the phenomenon of tire gnawing may be caused by improper use and maintenance. Therefore, it is necessary to conduct timely and regular inspections and maintenance on a regular basis. For more information, please visit our website http://www.lutongqixiu.com consulting service
