High-wet-wet-holding wet-skid-resistant tread rubber composition, mixing method and car tire

The invention provides a high-wet-wet-holding wet-skid-resistant tread rubber composition, a mixing method and a car tire, and belongs to the field of rubber tire manufacturing. The tread rubber composition with high wet grip and wet skid resistance comprises the following components in parts by mass: 20-40 parts of solution polymerized styrene-butadiene rubber I, 60-80 parts of solution polymerized styrene-butadiene rubber II, 3-5 parts of carbon black, 80-100 parts of high-dispersity white carbon black, 6-10 parts of a high-activity silane coupling agent, 2-5 parts of a white carbon black dispersing agent, 15-25 parts of wet skid resistance resin, 15-30 parts of operating oil, 3-5 parts of an active agent, 5-7 parts of an anti-aging agent and 3-6 parts of a vulcanizing agent and an accelerant, wherein the solution polymerized styrene-butadiene rubber I is a high-styrene high-molecular-weight styrene-butadiene random copolymer, and the solution polymerized styrene-butadiene rubber II is an ultrahigh-styrene
