Provided are a tire tread rubber composition which is enhanced in extrusion, durability and heat generation characteristics, is reduced in viscosity and is improved in processability, and a tire containing the tread comprising the composition. The composition comprises 1-5 parts by weight of zinc 2-ethyl hexanoate as the dispersion aid of a reinforcing agent based on 100 parts by weight of a rubber material. Preferably the rubber material is selected from a natural rubber, a synthetic rubber or a mixture of a natural rubber and a synthetic rubber in a ratio of 1:9 to 9:1. Optionally the composition comprises further carbon black, or a mixture of carbon black and silica as a reinforcing agent. |
