Provided is a rubber composition in which low heat build-up and tensile elongation at break are enhanced to or beyond conventional levels. The rubber composition contains a diene rubber including a styrene-butadiene copolymer component including at least one type of styrene-butadiene copolymer and a reinforcing filler. The styrene-butadiene copolymer component satisfies characteristics: (1) the bonded styrene content is from 5 to 50 wt.%; (2) the total amount of styrene of an ozone decomposed component S1 including one styrene-derived unit and an ozone decomposed component S1V1 including one styrene-derived unit and one 1,2-bonded butadiene-derived unit is less than 80 wt.% of the amount of bonded styrene, and the total amount of styrene of the decomposed component S1V1 is not less than 10 wt.% of the amount of bonded styrene; (3) the integrated intensity of an ozone decomposed component S1V2 including one styrene-derived unit and two 1,2-bonded butadiene-derived units is not less than 15% of the integrated intensity of all decomposed components including styrene-derived units; and (4) the vinyl content of a butadiene portion is not less than 20% and less than 50%.
