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

摘要

The present invention relates to a retreading tread rubber composition and a tire produced using the same. The retreading tread rubber composition comprises: 100 parts by weight of raw material rubber including 70 to 85 parts by weight of styrene butadiene rubber and 15 to 30 parts by weight of butadiene rubber; 50 to 55 parts by weight of phosphorous carbon black having a nitrogen adsorption specific surface area of 132 to 148 m^2/g and a DBP oil absorption amount of 108 to 120 cc/100 g; and 6 to 10 parts by weight of a processing material in which the weight ratio of potash soap and fatty acid ester is 1:1 to 1:3. The retreading tread rubber composition simultaneously satisfies wear resistance and durability and has excellent cut-chipping resistance.
