Object: Provided is a rubber composition with which rubber strength and wear resistance are enhanced to or beyond conventional levels. Solution Means: The rubber composition contains a diene rubber containing a styrene-butadiene copolymer component formed from at least one type of styrene-butadiene copolymers, and a reinforcing filler; the styrene-butadiene copolymer component formed from at least one type of styrene-butadiene copolymers satisfying that: (1) a bonded styrene content is from 5 to 50 wt.%; (2) a total of styrene content of an ozone-decomposed component S1 having one styrene-derived unit and styrene content of an ozone-decomposed component S1V1 having one styrene-derived unit and one 1,2-bonded butadiene-derived unit is less than 80 wt.% of the bonded styrene content and a total of styrene content of the ozone-decomposed component S1V1 is less than 10 wt.% of the bonded styrene content; (3) an integrated intensity of an ozone-decomposed component S1V2 having one styrene-derived unit and two 1,2-bonded butadiene-derived units is 15% or greater of an integrated intensity of all ozone-decomposed products containing a styrene-derived unit; and (4) a vinyl content of butadiene moiety is 50% or greater.
