The carcass of the used tire is made using laser technology x-rayed and severely damaged tires sorted out. Then the old one Tread rubber Removed to the contour using space machines. Then using Receipt extruder a new Raw rubber compound applied. Then the green tire moves into the Heating presswhere it gets the new profile under a pressure of 15 bar and at a temperature of 160 ° C. During this process the rubber goes through what is called vulcanization from the plastic to the elastic state.
Are retreaded tires more environmentally friendly?
Retreaded tires are definitely environmentally friendly as new tires. Every year around 60 million old tires on, but only half of it closes rubber granules processed, which is later used in sports parks as artificial turf or as a surface for running tracks or used for the production of insulating mats.
Since the carcass is also re-used for the production of retreaded tires, it comes to a Lower consumption of raw materials such as steel or rubber. Let's take a heavy truck as an example, which would be replaced by retreaded tires approx. 50 kg Raw material can be saved. It is also used in the manufacture of retreaded tires as well 80 percent less water, 70 Prozent less crude and 50 Prozent consumes less energy than when producing new tires.
What about security?
The retreading of tires has already proven itself over many years and is mainly used by Commercial vehicles often applied. Retreaded tires are often used in agricultural machinery, but can also be found in Motorsport or at aircraft frequently used. In the case of aircraft tires, it is statistically every third tire a Retreaded and the carcasses are usually up to seven times .
As with new tires, strict rules also apply to retreaded tires Requirements. According to the legislator, every carcass may once only to be rebuilt. Every further build is verboten. In addition, retreaded tires may only be sold in the EU if they are ECE R 108 standard suffice and about one E-mark feature. This is characterized by a special numeric code. The numeric code E1 stands for Germany, for example.
Retreaded tires also come with a "R" marked. This stands for "retread", "retread" or "retreaded". In addition to this designation, there are also the wheel size, which Speed class, the Load index and I baked the Date(s) The Retreading (DOT number). At New tires the DOT number would indicate the date of manufacture of the tires. PS: All information about the numbers and letters on the tire can be found in our article "Explanation!

And the quality of retreaded tires?
The quality of retreaded tires was determined by ADAC between 2003 and 2011 tested several times. While recycled winter tires did not initially perform ideally on snow, wet and dry roads, the level of retreaded tires has increased over the years significantly improved, especially on snow. The Ridgon MS179 von Ihle, for example, was even classified as "recommendable" by the ADAC. On Disadvantage of retreaded tires, however, is the volume. Since the connection between the substructure and the tread does not come from a single mold, recycled tires cause significantly more noise.
And there is also one major disadvantage: If you buy several (2 or 4 pieces) retreaded tires, there is a risk that you not on the same carcass are constructed, even if the tires have the same profile. At worst are 4 different carcasses under the same profile. This can lead to different driving characteristics the wheels lead. This can be dangerous in extreme situations, because it is not for nothing that the same type of tire is always fitted to the vehicle.
Due to the declining customer interest in retreaded tires, the ADAC ended the tests in 2011. In addition, many manufacturers had to file for bankruptcy because of the expenses for security technology such as X-ray procedure, Pressure test or Nail hole detectors were too expensive.
Better only on commercial vehicles!
Our conclusion: Even if retreaded tires are gaining in importance for economic and ecological reasons, they will not be able to displace cheap tires from the Far East from the market. Many drivers use new tires despite the lower price, as the origin of new tires can be clearly traced.
