In many of the most developed countries, companies that provide a number of services for the restoration of worn automobile tires are prosperily prospering. Even world-famous manufacturers of high-quality tires have subsidiaries that specialize in high-quality rubber restoration with an erased protector. Thus, the restored tires are returned back to the shelves of stores, the cracked economical car owners with their democratic price that is very different from the cost of similar car tires. However, the next question does not appear - is it safe to install such rubber on your car? About this further in the article.

Restored tires, what it is and who restores them

As is known, inside the rubber layer there is a tire frame, presented by a large number of layers of metallic Cord, as well as nylon (or other synthetic) tissue. It is very rarely subjected to essential wear, as it only contacts the top layer of the tread, erasing with each kilometer ride. Therefore, when the wheels are finally erased, the tire protector can be restored.

Essence of the event is quite simple - the worn protector is changed to a new one, applying different methods for this. Wheels are becoming suitable for use and provide an excellent level of security even on a wet or slippery track. But such rubber is somewhat inferior to a new one - its operational period is united twice as well, and the characteristics affecting manageability are most often far from reference.

Ways to restore tires

Automotive tires are restored by two main ways:

• By increasing the tread grooves, followed by the creation of its drawing.
• Cold and hot method of recovery by building a new tread:
  - With cold buildup, a new layer of the rubber ring is pasted on top of the existing tread.
  - With hot buildup, an additional rubber layer is applied using vulcanization.

restoration of auto strokes by increasing tread grooves, pros and cons

At the first method, the spent tire is carefully cleaned, and then the primary pattern of the tread is deepening further into the rubber layer, which, of course, entails its decrease. This method is not always safe, because the behavior of similar tires on the road cover is simply unpredictable.

cold extension of tread, pros and cons

At first, the rubber is diagnosed, in the process of which the damage to the tires obtained during operation is analyzed. In the second stage, the worn protector is removed. The tire is placed in a special apparatus, in which it is pumped with air and remove the upper rubber layer from it. The subsequent third stage is called roughing. It can be installed on it, which tires are worn very much, and to cut them out. Wheels, which can still be restored, get rid of insignificant shortcomings, for example, punctures and cuts.

Restoration of the rubber tire tread requires the possession of a number of certain skills. A new rubber ring is covered with liquid rubber, allowing quality and reliably to remove old damage, thereby providing a sufficiently dense contact of the frame with a tread. Ground the wheel using a manual extruder, after which they impose a protector with a special pattern. Then, on a fully inflated tire, the rubber layer is cut around the wheel circumference. With the help of special equipment, the tire is folded as an envelope, and then put on the rim and on the camera. After that, the renovated rubber is subject to vulcanization in a special automated autoclave, in which the protector ring is securely attached, merging together with the frame. Then the rim and the camera is dismantled. Next, the recovered bus re-passes the diagnostics and is equipped with a warranty coupon.

hot tread extension, pros and cons

This method is similar to the previous one in the following moments:

1. Initial diagnostics.
2. Roughing.
3. Basic repair.
4. The imposition of a new rubber layer.

However, despite this, such processes of restoration of automotive rubber differ significantly. With the help of the previous method, you can reanimate automotive tires of large diameter: tires of large-sized equipment, trucks and SUVs.

The hot method is made in this way: a simple layer of rubber is imposed on a worn tire, not vulcanization. Then the protector is applied at the time of vulcanization. The new tread ornament is applied to molds operating at a temperature of 140 degrees Celsius under great pressure. To date, this method is used very rarely, but it is optimal for minibuses and passenger cars with R13-R16 tire size.

What tires can be restored, and which you can not

Unfortunately, not all tires are restored. Here it is necessary to take note of the state of their frames. The side and inner sides of the tire, its crowns and board should be to the maximum extent, because it is precisely the key to the subsequent possibility of using.

What guarantees receive restored tires

As the manufacturers, tires restored by the right technology, can pass no less than a new tires, and some automotive services are guaranteed to their restored tires per hundred thousand kilometers of the run.

How to distinguish restored rubber

If you are dealing with high-quality tires, on the sidewall of the restored tire you will see a special labeling, which means that the rubber gave the second life. Usually it looks like the inscription Regummerat, Remold or Retread, depending on the version that can be German, American or English. If the restoration was produced in Ukraine, then you will see a familiar word - "Vidnolen".

You can also meet other distinctive properties of tires that have been subject to recovery. For example, a peculiar mesh of microcracks on the side of the bus, which the recovery process did not touch, or rubber bunches that are on the inner part of the tire indicate the elimination of the buses of the tire or repair. In any case, the recovered rubber is not difficult to distinguish from the new, most importantly - carefully examine the goods.

Advantages and disadvantages of restored tires

If the car owner faces the purchase of new or recovered tires, it must be aware of all risks that previously used tires are subjected. As already mentioned above, there are several methods for restoring automotive rubber. A lot of funds spend on such an event, since specialized equipment, high-quality restoration materials and trained personnel are necessary.

No one is secret that most motorists are more oriented on products imported from abroad, because the worn tire renovated by our materials is obtained by controversial reliability and quality. However, it is quite expensive to apply foreign consumables.

It is possible to restore passenger tires only with a small wear, however, as practice shows, it is simply impossible, and only units with optimal external data are subject to restorations. In addition, it is not always possible to carry out the wheel balancing with restored tires, and this is a significant drawback.

So, if this technology has so many negative moments, then why is it used? In fact, everything is not so bad as at first glance it might seem. A vehicle with an impressive mileage running for a short time interval will be perfectly riding for reanimated tires. Sensible masters can quickly, reliably and efficiently restore such tires in the presence of the equipment required. Restored winter tires will allow to save considerable funds. Professionals can do the following:

1. Eliminate microcracks using thermal seating.
2. Repair the cord by overlaying new threads.
3. The most worn out areas are increasing with ultrasound research or rolled products.
4. The new layer is glued to the bus so that the tire looks like a new one.
