Abstract: The present process allows recycling used tires which are at present considered to be no longer suitable for restructuring according to known processes.According to the invention a preliminary control is carried out, also by scanning by means of a laser, to assess the seriousness of the internal ruptures and deformations due to impacts or other causes, discarding tires which are too damaged, while the thread and the metallic belts of the remaining tires which can be used are removed therefrom by scraping, the entire tire assembly being reconstructed, by vulcanizing before mounting the tread, and checking again with the laser to detect bubbles or other defects correcting the defects, obtaining a perfect assembly (FIG. 25) on which the tread which is vulcanized again, is lastly mounted.
