More Information
Summary:A tire tread comprises a rubber composition based on at least: an elastomer matrix comprising more than 50% by weight of a solution SBR bearing a silanol function and an amine function, a reinforcing filler present at a content of between 40 and 80 phr, which reinforcing filler comprises between 40 and 80 phr of a silica, a coupling agent for coupling the silica to the solution SBR, 10 to 50 phr of a hydrocarbon-based resin having a Tg of greater than 20° C., and 0 to less than 5 phr of a liquid plasticizer. Such a tire has a good performance compromise between rolling resistance and wet grip.
