The concrete is easy to dry, especially when it is transported for a long distance, because the mixer can not only realize the long-distance transportation, but also continuously mix the concrete in the transportation process. Don't let it dry to powder. During this period of time, the tire keeps contacting with the ground and grinding. How to judge whether the tire of zhongkejufeng mixer needs to be changed:

1. 胎面花紋深度

1. Tread depth

胎面厚度必須大于1.6毫米，如果你經常在低摩擦的濕滑路面上駕駛，厚度必須加倍。

The tread thickness must be greater than 1.6mm. If you often drive on a slippery road with low friction, the thickness must be doubled.

2. 胎面花紋磨損指示線

2. Tread pattern wear indicator line

全自動自上料攪拌車花紋磨損指示線。當磨損達到一定程度時，這些隱藏的線就會出現在胎面皺紋中。胎面花紋磨損指示線是與胎面垂直嵌入胎面凹槽內的扁橡膠條。如果幾乎所有的輪胎上的引導線都是清晰可見的，這意味著你需要盡快更換輪胎。

Concrete mixer pattern wear indicator line. When the wear reaches a certain level, these hidden lines will appear in the tread wrinkles. The tread pattern wear indicator line is a flat rubber strip vertically embedded in the tread groove with the tread. If the guide lines are clearly visible on almost all tyres, this means that you need to change the tyres as soon as possible.

3.輪胎側壁裂紋

3. Tire sidewall crack

輪胎的問題并不都集中在胎面，側壁也有問題。檢查輪胎側壁是否有明顯的裂縫和切口。這些細小的凹槽可能預示著輪胎在未來的泄露和裂縫，甚至會導致輪胎爆裂。因此，當輪胎側壁裂紋較嚴重時，建議考慮更換輪胎。

The problems of tyres are not all concentrated on the tread, but also on the sidewall. Check the tire sidewall for obvious cracks and cuts. These small grooves may indicate the leakage and crack of the tire in the future, and even cause the tire to burst. Therefore, when the sidewall cracks of the tire are serious, it is recommended to consider changing the tire.

4. 輪胎上的腫塊和水泡

4. Bumps and blisters on tires

在某些情況下，混凝土攪拌輪胎的外表面不夠牢固，導致在正常的輪胎表面上出現顛簸和水泡。就像血管里的動脈瘤一樣，輪胎也有類似的情況。如果不及時修理，胎面強度不足的地方可能會引起突然的爆裂。

In some cases, the outer surface of the concrete mixing tire is not firm enough, resulting in bumps and blisters on the normal tire surface. Like an aneurysm in a blood vessel, a tire has a similar condition. If not repaired in time, areas with insufficient tread strength may cause sudden burst.

如果發現全自動自上料攪拌車的輪胎符合上述條件之一，則意味著輪胎應該更換。無論輪胎是否癟，無論使用多長時間，需要更換的輪胎都要更換新輪胎，以保證駕駛安全。

If it is found that the tyres of the concrete mixer meet one of the above conditions, it means that the tyres should be replaced. No matter whether the tire is flat or not, no matter how long it is used, the tire that needs to be replaced must be replaced with a new one to ensure driving safety.
