What are the uses of scrapped tires? What are the standards for scrapping tires?

Tires are the guarantee for the normal driving of cars. The life of tires is generally three years. After three years, tires will age rapidly. If there is a problem with the tire, it should be scrapped and replaced in time. Tires can still be recycled after being scrapped. Let's learn about it together.

What are the uses of scrap tires?

The best way to treat tires is to physically crush and roll to extract steel wire, process the pellets and extract tire oil by pyrolysis, and then activate the remaining tire carbon black into high value-added activated carbon. And one furnace can complete the pyrolysis and activation continuously. There is no odor and no wastewater. Compared with activated carbon, tire oil is a low value-added resource.

Scrapped car tires can also be recycled and crushed into tiny particles, which can then be mixed with sand and asphalt in proportion to pave highway roads. Not only can waste be reused, which is beneficial to environmental protection and reduces costs, but the road surface mixed with rubber particles can greatly reduce tire noise and greatly improve comfort.

What is the tire scrapping standard?

Tread wear indicator line is obvious

The tread wear indicator lines are a row of flat rubber strips that are perpendicular to the longitudinal direction of the tread and embedded in the grooves of the tread. When one or two indicator lines are visible on the tire, it means that the thickness of the tread has been greatly reduced. At this time, remember not to drive too fast on slippery roads. If all indicator lines are basically visible or are parallel to the tread, replace the tire as soon as possible!

Tread pattern worn flat

If the tread pattern is completely flat, the friction between the tire and the ground will be greatly reduced, making it difficult to brake in time.

You can use our one-yuan coin to insert it into the tread groove vertically along the chrysanthemum pattern. If you can see the English under the chrysanthemum, the thickness of the pattern is already thin to the critical point of a tire burst.

Tread bulge

This type of tire is most likely to burst while driving and should be sent to a repair shop immediately for a tire replacement.

Tire sidewall cracks

There will be some obvious cracks and cuts on the sidewall of the tire, most of which are caused by scratches from foreign objects such as stones and iron sheets on the road. These small cracks may evolve into air leakage cracks. If the cracks are very large and deep, it is best to replace the tire, otherwise it will greatly increase the probability of tire bursting.

Why can't the new tire detect tire pressure?

First of all, none of the four tires could be detected, and only the newly replaced tires could not be detected.

If only the newly replaced tire cannot be detected, you should consider whether the sensor of this tire was damaged during the tire blowout. The sensor is installed inside the wheel hub and fixed at the valve stem. In the case of a tire blowout, it is normal for the strong airflow to damage the sensor. It is recommended to buy a new sensor for replacement.
