RUBBER COMPOSITION FOR TIRE TREAD AND TIRE MANUFACTURED BY USING THE SAME

摘要

The present invention relates to a rubber composition for a tire tread and a tire manufactured by using the same. The rubber composition for a tire tread contains 10-120 parts by weight of silica, and 5-30 parts by weight of a reinforcing dispersant produced by dry-mixing a carbon black particle of which an iodine adsorbing capacity is 87-147 mg/g, an oil adsorption specific surface area is 97-135 cc/100 g, and a TINT value is 122-132 with a silane coupling agent particle at a temperature of 40°C or higher at a ratio of 7:3-1:1 with respect to 100 parts by weight of raw rubber containing styrene-butadiene rubber and neodymium polybutadiene rubber at a ratio of 80:20-50:50. The rubber composition for a tire tread according to the present invention is capable of improving abrasion resistance and cut-chip performance while maintaining fuel efficiency performance and improving the appearance properties of a tire including a coloring degree.
