Provided is a rubber composition that exhibits improved low heat build-up up to or beyond levels in the related art while maintaining wear resistance. The rubber composition contains a diene rubber component and a reinforcing filler, and the diene rubber component contains a styrene-butadiene copolymer component including at least one type of styrene-butadiene copolymer and satisfying the following requirements: (1) the bonded styrene content is from 5 to 50 wt.%; (2) of components obtained by ozone decomposition, a content of a decomposed component V1 containing one 1,2-bonded butadiene-derived unit out of a total of 100 mol% of decomposed components containing styrene-derived unit(s) and/or the 1,2-bonded butadiene-derived unit(s) is not less than 25 mol%; (3) of the components obtained by ozone decomposition, a content of a decomposed component S2V1 containing two of the styrene-derived units and one of the 1,2-bonded butadiene-derived unit out of a total of 100 mol% of the decomposed components containing the styrene-derived unit(s) and/or the 1,2-bonded butadiene-derived unit(s) is not less than 5 mol%; and (4) a vinyl content of a butadiene moiety is not less than 50%.
