The present invention relates to a rubber composition for a high-speed energy-saving tire tread, and belongs to the technical field of tire and rubber processing. The rubber composition comprises the following components: 100 parts by mass of HVPBR, 10-50 parts by mass of white carbon, 0-40 parts by mass of carbon black, and 0-2.7 parts by mass of a silane coupling agent, wherein a total amount of the white carbon and the carbon black is 50 parts by mass. Compared with the conventional rubber material for a tire tread, the rubber composition contains high vinyl polybutadiene with a branched structure, so that the consistency of the white carbon and a rubber material is improved, and the processability is improved. On the premise of ensuring excellent wet traction, the rolling resistance and dynamic heat build-up of the tread are reduced without causing obvious loss of traction force, thereby meeting a development concept of low-carbon economy that is currently advocated.
