Abstract:
A tire tread includes a plurality of elements in relief (rib and/or block) having lateral faces, and a contact face intended to come into contact with the roadway during travel. The intersection of each lateral face with the contact face forms a ridge. The tread also includes a plurality of cutouts each defined by opposing main faces. Each tread pattern element is formed with at least one base mix. As viewed in section in a plane containing the thickness of this tread, at least one face defining at least one cutout is formed at least in part with a covering mix. The base mix exhibits a gripping action on wet ground which is lower than a gripping action of the covering mix on the same ground.
