A tread for a tire 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 90 phr and 150 phr of silica filler with an organosilane coupling agent having in some embodiments no or little sulfur content. A plasticizing system includes a high Tg plasticizing resin and may include 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 0.6 MPa and 1.5 MPa and a measured Tg of between −30° C. and 0° C. The elastomer composition is cured with a peroxide curing system.
