A RUBBER COMPOSITION

摘要

The present invention relates to a rubber composition based on between 50 and 120 phr of a reinforcing filler, on a plasticizing system comprising a content A of between 15 and 65 phr of a liquid plasticizer exhibiting a Tg of less than -65°C and a content B of between 1 and 25 phr of a hydrocarbon resin exhibiting a Tg of more than 20°C, a total content A+B being between 30 and 80 phr, on an elastomer matrix that is reactive to the crosslinking system, which elastomer matrix comprises an elastomer A comprising monomer units of a first methacrylic acid ester which represent at least 20 mol% of the monomer units of the elastomer A, and on a crosslinking system. The rubber composition makes it possible to improve the dry grip of tires whose tread consists of the rubber composition, without degrading, or even while improving, the snow grip of tires.
