A rubber component for a tire is disclosed that is manufactured from a rubber composition that is based upon a cross-linkable elastomer composition that includes 100 phr of two elastomer types including at least 50 phr of a styrene-butadiene copolymer (SBR) with a polybutadiene (BR) as the remainder. Such compositions may further include between 75 phr and 130 phr of a carbon black. Also included in such elastomers is a plasticizing system that includes a plasticizing resin having a glass transition temperature (Tg) of at least 25° C. and a plasticizing liquid. The plasticizing system is added in an effective amount to provide the cured rubber composition with a shear modulus G* measured at 60° C. of between 0.7 MPa and 1.6 MPa and a measured Tg of between −30° C. and 0° C. The elastomer composition is cured with curing system that includes both a peroxide and sulfur.
