The present invention relates to a rubber composition of a tire tread having improved dispersion by fundamentally solving the problem of dispersion in rubber of carbon nanotubes, and a tire manufactured using the same. The rubber composition of the tire tread according to the present invention contains 1 to 100 parts by weight of the raw rubber/carbon nanotube master batch per 100 parts by weight of the raw rubber, and the raw rubber is made of natural rubber, synthetic rubber, or a combination thereof. It is any one selected from the group consisting of, and a tire is manufactured with the above composition. According to the present invention, by using a master batch in which carbon nanotubes are dispersed in the raw material rubber in advance, the reinforcing property is very good, so it is very advantageous in the abrasion performance, and it is advantageous in the heat generation performance by replacing carbon black as much as the improved reinforcing property. It works. |
