Abstract
Rubber composition based on at least one reinforcing filler comprising a reinforcing inorganic filler, one plasticizing system composed of at least one plasticizing hydrocarbon resin and one liquid plasticizer, one elastomer which is a copolymer at least of isoprene and styrene bearing at least one SiOR functional group, R being hydrogen or a C1-C10 alkyl, C5-C18 cycloalkyl, C6-C18 aryl or C7-C18 aralkyl radical, and one coupling agent for bonding the inorganic filler to the elastomer. A tire, the tread of which comprises such a composition exhibits an improved wet grip.
