The invention relates to the technical field of rubber materials, discloses a rubber composition for a new energy automobile tire, and solves the problem that the wear resistance, the braking performance on an icy road surface and a snowy road surface and the low oil consumption performance of an existing tire cannot be effectively balanced. The rubber composition is prepared from, by weight, 30-60 phr of polyisoprene rubber, 10-30 phr of polybutadiene rubber, 30-60 phr of styrene and butadiene copolymer, 40-70 phr of carbon black, 5-20 phr of white carbon black and 0.5-3.5 phr of carbon black coupling agent. The rubber composition for the new energy automobile tire not only can effectively improve the wear resistance of the tire, but also can improve the braking performance and low oil consumption performance of the tire on icy pavements and snowy pavements.
