The rubber composition includes: 20 to 100 phr of a first diene elastomer bearing at least one SiOR function, with R being hydrogen or a hydrocarbon radical, and with phr referring to parts by weight per hundred parts of elastomer; 100 to 160 phr of a reinforcing inorganic filler; and a plasticizing system. The plasticizing system includes: a content A of between 5 and 60 phr of a hydrocarbon resin having a Tg above 20° C.; and a content B of between 5 and 60 phr of a liquid plasticizing agent.

摘要： A tire, the tread of which comprises a rubber composition comprising a diene elastomer, such as, for example, an SBR or BR elastomer, a poly(vinyl ester) resin, at a content preferably of between 5 and 50 phr, and a reinforcing filler, such as silica and/or carbon black. The poly(vinyl ester) resin is in particular a vinyl ester homopolymer or copolymer of formula R—C(═O)O—CH═CH2, at least one of the vinyl ester monomers of which comprises a radical R having more than 2 carbon atoms, preferably from 4 to 20 carbon atoms. Such a composition makes it possible to improve the wet grip of the treads of the tire and also the processability of such a composition.

摘要： A layer of cellular material forms a running layer (14A) of a tread (14) in which tread pattern elements (20, 22, 26) are made. In order to form the cellular material, an uncured blank is provided with a mass of material comprising p,p′-oxybis(benzenesulphonyl hydrazide) that forms a pore-forming agent. The uncured blank is placed in a vulcanization mold (28) comprising molding elements (30, 32, 34). At least 95% of the molding elements (30, 32, 34) each satisfy the following two conditions: a) the molding element (30, 32, 34) is separated from at least one other molding element (30, 32, 34) by a distance, expressed in millimetres, of less than or equal to DM=6.85+0.0065 T3, T, greater than or equal to 3 phr, being the amount of p,p′-oxybis(benzenesulphonyl hydrazide) in the mass of material intended to form the cellular material,b) the molding element (30, 32, 34) is intended to form a tread pattern element (20, 22, 26) having a depth at least equal to 80% of the thickness of the running layer (14A).
