| abstract |
The present invention relates to a tyre, the tread of which comprises a rubber composition comprising a diene elastomer such as, for example, an SBR or BR elastomer, a polyvinyl ester resin, at a level preferably between 5 and 50 phr, a reinforcing filler such as silica and/or carbon black. The polyvinyl ester resin is in particular a homopolymer or a copolymer of vinyl ester, of the formula R-C(=O)O-CH=CH 2 , at least one of the vinyl ester monomers of which comprises a radical R having more than 3 carbon atoms, preferably from 4 to 20 carbon atoms. Such a composition improves the grip of tyre treads on wet ground, and also the processability of such a composition. |
