Abstract: Tire treads having improved traction properties while surprisingly still maintaining good material cohesion properties, the tire treads comprising a rubber composition based upon a highly unsaturated diene elastomer and between 95 phr and 160 phr of an inorganic reinforcing filler. The composition may further include between 60 phr and 130 phr of a plasticizing system made up of a plasticizing resin having a Tg of at least 25° C. and a plasticizing liquid. The rubber composition is cured with an ultra-efficient sulfur curing system having a sulfur to accelerator weight ratio adjusted between 0.02 and 0.2 to provide the rubber composition with an MA300/G* ratio of greater than 1.7, wherein the elongation modulus MA300 at 300% is measured at 23° C. and the shear modulus G* is measured at 60° C.
