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. 胎面花纹深度

1. Tread depth

胎面厚度必须大于1.6毫米，如果你经常在低摩擦的湿滑路面上驾驶，厚度必须加倍。

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. 胎面花纹磨损指示线

2. Tread pattern wear indicator line

全自动自上料搅拌车花纹磨损指示线。当磨损达到一定程度时，这些隐藏的线就会出现在胎面皱纹中。胎面花纹磨损指示线是与胎面垂直嵌入胎面凹槽内的扁橡胶条。如果几乎所有的轮胎上的引导线都是清晰可见的，这意味着你需要尽快更换轮胎。

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.轮胎侧壁裂纹

3. Tire sidewall crack

轮胎的问题并不都集中在胎面，侧壁也有问题。检查轮胎侧壁是否有明显的裂缝和切口。这些细小的凹槽可能预示着轮胎在未来的泄露和裂缝，甚会导致轮胎爆裂。因此，当轮胎侧壁裂纹较严重时，建议考虑更换轮胎。

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. 轮胎上的肿块和水泡

4. Bumps and blisters on tires

在某些情况下，混凝土搅拌轮胎的外表面不够牢固，导致在正常的轮胎表面上出现颠簸和水泡。就像血管里的动脉瘤一样，轮胎也有类似的情况。如果不及时修理，胎面强度不足的地方可能会引起突然的爆裂。

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.

如果发现全自动自上料搅拌车的轮胎符合上述条件之一，则意味着轮胎应该更换。无论轮胎是否瘪，无论使用多长时间，需要更换的轮胎都要更换新轮胎，以保证驾驶。

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.
