Abstract
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.
