The invention belongs to the application field of production and manufacturing industries of tires, automobiles and the like, and relates to a low-rolling-resistance tread rubber composition, a mixing process method thereof and a tire. The rubber composition is prepared from the following components in parts by weight: 25.0 to 50.0 parts of natural rubber, 5.0 to 30.0 parts of non-oil-extended solution polymerized styrene-butadiene rubber A, 40.0 to 80.0 parts of oil-extended 20 percent solution polymerized styrene-butadiene rubber B, 40.0 to 50.0 parts of white carbon black with high specific surface, 0.5 to 10.0 parts of carbon black, 1.0 to 6.0 parts of white carbon black dispersing agent, 2.0 to 10.0 parts of grip resin, 1.0 to 5.0 parts of sulfydryl silane coupling agent and 0.1 to 3 parts of zinc dialkyl dithiophosphate. The rubber composition disclosed by the invention has relatively low rolling resistance and good wet land gripping performance.
