Claim:
Rubber pellets obtained from used tires by a process comprising: a) collecting used tires having a tread and lateral faces, in which the tread includes an inner layer and an outer layer, and each lateral face includes a flange at the inner edge thereof; b) separating the tread from the lateral faces; c) cutting the tread transversely through the inner layer and the outer layer in order to form a strip from the tread; d) cutting the strip obtained in the previous step in order to form pellets therefrom in two stages: i) in the first stage, making longitudinal and parallel cuts over the tread strip, thus forming a first plurality of thinner strips; and ii) in the second stage, making transverse and parallel cuts over the thinner strips in order to form the rubber pellets; e) detaching the flange from the lateral faces which were separated in step (b); and; f) cutting the flange-less lateral faces from step (e) in order to form pellets therefrom, wherein the rubber pellets obtained from the tread and the lateral faces have a size between 6.4 mm and 50.8 mm and have a regular quadrangular or rhomboidal shape.
