When a hydrogenated copolymer and a liquid rubber are used in combination, the rubber composition for a tire having improved break strength and wear resistance while maintaining the processability that is a characteristic of the liquid rubber, and air using the same Provide filled tires. (A) A hydrogenated copolymer obtained by hydrogenating an aromatic vinyl-conjugated diene copolymer, having a weight average molecular weight of 300,000 or more measured by gel permeation chromatography, and hydrogenation of a conjugated diene part A hydrogenated copolymer having a rate of 80 mol% or more, a rubber component containing (B) liquid rubber, and sulfur, and in 100 parts by mass of the rubber component, the hydrogenated copolymer (A) Is 80 to 95 parts by mass, the liquid rubber (B) is 5 to 20 parts by mass, and the sulfur content is 15 to 30 parts by mass with respect to 100 parts by mass of the liquid rubber (B). It is set as the rubber composition for tires characterized by being a part. |
