The invention relates to the field of rubber technology and in particular to a 1,2-polybutadiene resin-containing car tire tread rubber composition. The 1,2-polybutadiene resin-containing car tire tread rubber composition is characterized by also comprising 30-60 parts of high abrasion furnace black or medium super abrasion furnace black by weight, 20-50 parts of high dispersion white carbon black by weight, 5-10 parts of a silane coupling agent by weight, 10-30 parts of a rubber processing softener by weight, 1.0-5.0 parts of zinc oxide by weight, 1.0-2.5 parts of an antiager RD by weight, 1.0-4.5 parts of an antiager 4020 by weight, 1.5-4.0 parts of sulphur by weight, 0.5-4.0 parts of an accelerant by weight and 0.01-1 part of a scorch retarder by weight by taking 100 parts of rubber component by weight as a benchmark, wherein the rubber component comprises 55-75 parts of styrene-butadiene rubber by weight, 10-30 parts of high cis-1,4 polybutadiene rubber by weight and 5-20 parts of 1,2-polybutadiene resin by weight; the styrene-butadiene rubber comprises 15-60% of styrene by mass and 10-50% of vinyl by mass; and the mass percent of butadiene in poly-1,2 butadiene rubber is greater than 93%.
