Abstract
The removal of the tread consists in grasping a zero-degree reinforcement rd, which the crown of the tire must necessarily contain in order to apply this method, and pulling transversely on it until it is completely removed from the tire. In this way, the tread is very easily separated from the carcass of the tire.
