Zusammenfassung:The present disclosure relates to a coextrusion process for manufacturing a profiled element intended to form a tread for a pneumatic tire. The process includes coextruding a first elastomer compound forming an underlayer and reinforcing wedges, a second elastomer compound forming tread pattern blocks supported laterally by the wedges, and a third elastomer compound. The third elastomer compound is different from the first and second elastomer compounds and is interposed between the lateral wall of each wedge and the corresponding tread pattern block so as to form a decoupling interface for separating the mechanical behavior of the wedge from that of the tread pattern block.
