摘要： A tire tread comprising a rubber composition based on at least a diene elastomer, a reinforcing inorganic filler such as silica, an inorganic filler/elastomer coupling agent and carbon black in a very small quantity, in an amount of between 0.05 and 2.0 phr. The tires comprising such a tread have, after photo-oxidation treatment of the latter, a significantly improved grip on wet roads. Such photo-oxidizing treatment, in particular under visible UV radiation, may advantageously be performed during the manufacture of the treads or tires itself, in the uncured state or after vulcanization, or even later on in the life of said tires.

摘要： 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 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, wherein at least one first base mix opens on to the contact face (2) when new or at the latest after wear at most equal to 10% of the height Hr. The base mix has an amount of carbon black greater than 2 phr of black and the covering mix has an amount of carbon black greater than 0 phr and at most equal to 2 phr.

摘要： The invention relates to a rubber composition based on one or more specific functionalized diene elastomers and on one or more carbon blacks with a CTAB specific surface varying from 100 to 200 m2/g, the functionalized diene elastomer or elastomers being composed of a specific diene elastomer functionalized, at the chain end or in the middle of the chain, by a tin functional group and of a content of less than 15% by weight, with respect to the total weight of the functionalized diene elastomer, of a non-tin functional elastomer. The diene elastomer exhibits a monomodal distribution of molecular weights before functionalization and a polydispersity index before functionalization of less than or equal to 1.3. This composition makes it possible to obtain tires having an improved wear resistance and which are characterized by decrease in rolling resistance, without damaging the processing and the wet grip.
