“啃胎”就是指一個或幾個車輪胎發生不正常的快速磨損，那么，車友們所言的“啃胎”究竟有哪幾種磨損類型?下面
濟南沃爾沃汽車養護人員為您講解：
'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
輪胎磨耗
Tire center wear
輪胎磨耗嚴重通常是由于氣壓過高，胎面需要承受車輛的載重，增加了胎面的摩擦。車輛會跳動，舒適性也會降低。
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
雙側胎肩磨耗
Bilateral shoulder wear
輪胎氣壓不足，兩側胎肩就會凸起，從而造成磨損過快，而且胎壓不足會引起油耗增大，還會造成輪胎缺氣被碾壓損毀。
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
單邊磨耗
Unilateral wear
高速轉彎時由于慣性力和離心力的作用，使車內貨物傾斜一側，造成單邊輪胎超載拖曳，加速輪胎磨損。
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.
4
four
花紋呈鋸齒狀磨損
The pattern shows serrated wear
鋸齒狀磨損主要是因為前輪定位調整不當或前懸掛系統位置失常、球頭松曠等，使正常滾動的車輪發生滑動或行駛中車輪定位不斷變動而形成。
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
胎面花紋的局部磨損
Local wear of tread patterns
很明顯是由于緊急制動使車輪抱死，或者快速起步使車輪打滑引起的胎面局部磨損，應該盡量避免緊急制動與急速起動。
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、至少每個月檢查一次車上所有輪胎在冷卻情況下的氣壓，胎壓過低或過高，胎面磨損都會加快，好根據汽車車門下角的規定胎壓進行充氣。
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、感覺輪胎有擺動，要及時進行輪胎動平衡檢測，如果不平衡要加裝平衡鉛塊保持平衡，以免發生“啃胎”現象。
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、時常檢查輪胎是否有鼓包、裂縫、割傷、扎釘和不正常的磨耗。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.yiyili.com consulting service
