PROBLEM TO BE SOLVED: To provide a rubber composition that exhibits an excellent traction performance, while retaining the balance between reduced rolling resistance and wear resistance at a high level, and a tire using the composition. SOLUTION: The rubber composition includes (A) a diene rubber, (B) a metal soap expressed by formula (I), and (C) a carbon black for rubber compounding that has specific characteristics obtained by a specific production process and meets specific requirements [wherein, M is a metal having an oxidation state of +3 or +4; R is an each independently selected organic portion; and n is the valency of M].
