Ultra-low rolling resistance all-steel radial tire tread rubber composition

The invention relates to the technical field of a tire rubber, in particular to an ultra-low rolling resistance all-steel radial tire tread rubber composition, which is characterized by being preparedfrom the following raw materials in parts by weight: 65-70 parts of natural rubbers, 50-60 parts of wet-mixed natural rubbers, 20-30 parts of reinforcing fillers, 5-10 parts of silane coupling agents, 1-5 parts of plasticizers, 5-10 parts of active agents, 2-6 parts of antioxidants, 1-5 parts of vulcanizing agents and 2-5 parts of vulcanization accelerators. The wet-mixed natural rubber is applied to replace part of the natural rubbers and part of the white carbon black, and the white carbon black is evenly dispersed in the natural rubbers by the wet method, so that the mooney viscosity of acomposition can be effectively reduced, the problem of poor mooney processability of a high white carbon black composition is solved, and meanwhile, the dispersibility of the filler in the compositionis increased. The tread ru
