Abstract: A tire tread comprising a plurality of elements in relief (1) comprising a contact face (2) intended to come into contact with the roadway during travel and lateral faces (13, 14, 15, 16), the intersection of each lateral face with the contact face forming a ridge (23, 24, 25, 26). The tire tread also comprises a plurality of cutouts (3, 4) in the form of grooves and/or incisions, said cutouts being defined by facing main faces. Each tread pattern element (1) is formed with at least one rubber mix (referred to as “base mix”). This tread, viewed in section in a plane containing the thickness of this tread, has at least one face defining at least one cutout covered at least in part with a second rubber mix, referred to as “covering mix”, this part having covering mix extending when new over a height Hr at least equal to 30% of the height H of the face, and wherein at least one first base mix opens on to the contact face when new or at the latest after wear at most equal to 10% of the height Hr. The covering mix comprises a butyl rubber and the covering mix comprises a plasticiser of the type unsaturated C12-C22 fatty acid ester.

Abstract: The invention relates to a tread for pneumatic tyres with an improved capacity for adhesion to wet ground. Said tread consists of a rubber composition containing at least: (i) one dienic elastomer comprising more than 30 pce of rubber butyl, (ii) a reinforcing inorganic load such as silica, (iii) a coupling agent for the inorganic load, and, as a plastifying agent, (iv) a glycerol unsaturated fatty acid triester (C12-C22), especially a glycerol trioleate. The invention also relates to the use of one such tread for the production or the retreading of pneumatic tyres, and to the pneumatic tyres themselves.
