The invention provides a graphene modified rubber composition and graphene tread rubber, and the graphene modified rubber composition comprises the following components based on 100 parts by weight of matrix rubber: 80-100 parts of natural rubber, 0-20 parts of synthetic rubber, 0.1-6 parts of a graphene dispersion, 10-60 parts of a reinforcing agent, 0.5-6 parts of a coupling agent, 1-8 parts of an active agent, 1-8 parts of an anti-aging agent, 0.5-3 parts of sulfur, 0.5-5 parts of an accelerant, 0.5-2 parts of an anti-reversion agent and 0.1-0.3 part of a scorch retarder, wherein the graphene dispersion comprises graphene and a dispersing agent, and the weight ratio of the graphene to the dispersing agent is 1: (0.05-1). The high-strength and high-wear-resistance graphene tread rubber is obtained by controlling the size of graphene, dispersing the graphene, taking the natural rubber and the high-structure carbon black as the basis and selecting other rubber additives in a reasonable ratio, and is suitable for the technical fields of truck tires, engineering tires, aircraft tires and the like.
