1. A method for manufacturing a tread based on uncured rubber material comprising:
forming a green form of tread based on uncured rubber material having at least one tread pattern block, each tread pattern block having a central portion and at least one lateral portion extending along the central portion;
mounting at least one reinforcing ply on at least a part of the central portion; and
covering the central portion with the aid of the lateral portion in order that the tread pattern block envelops the at least one reinforcing ply,
wherein the central portion has a prismatic shape with a triangular base, at least two adjacent faces of the triangular base being intended to receive the reinforcing ply.
