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. Tread depth
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. Tread pattern wear indicator line
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. Tire sidewall crack
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. Bumps and blisters on tires
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.
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.
