Provided are a tire tread rubber composition which is improved in the dispersion of a reinforcing agent and is excellent in abrasion resistance, and a tire containing the tread comprising the composition. The tire tread rubber composition comprises 10-40 phr of a carbon nanotube; and 1-3 phr of sodium dioctyl sulfosuccinate for improving the dispersion of the carbon nanotube, based on 100 phr of a rubber material. Preferably the carbon nanotube is a single-wall carbon nanotube or a multi-wall carbon nanotube. 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. |
