Abstract: Rubber articles, including tires and tire treads, that are manufactured from a rubber composition that includes a functionalized styrene-butadiene rubber (SBR) and a polybutadiene rubber, wherein the functionalized SBR includes a functional group attached as an active moiety and wherein the butadiene portion of the SBR has as trans-1,4 content of between 30 wt. % and 70 wt. %. The rubber composition further includes a plasticizing system having a plasticizing resin having a glass transition temperature (Tg) of at least 25° C. and a plasticizing liquid, wherein the plasticizing system is added in an effective amount to provide the rubber composition with a glass transition temperature of between −25° C. and −15° C. and with a dynamic modulus G* at 60° C. of between 0.8 MPa and 1.3 MPa. The rubber composition is reinforced with a silica filler.
