Abstract
Rubber compositions and articles made such rubber compositions having at least 80 phr of a styrene-butadiene elastomer modified with a functional group that is capable of interacting with a silica reinforcing filler and having a glass transition temperature of between −60° C. and less than −40° C. The rubber compositions may also include an effective amount of a plasticizing system having a plasticizing resin and a plasticizing liquid, wherein the effective amount of the plasticizing system provides the rubber composition with a shear modulus G* measured at 60° C. of between 0.9 MPa and 1.5 MPa and a Tg of between −35° C. and −15°. The filler for the rubber compositions is silica and there is further a curing system.
