Rubber composition and tire using same

A rubber composition prepared by mixing 60 to 100 parts by mass of a filler (B), 0.9 to 2.4 parts by mass of a phenol resin (C), 0.07 to 0.2 parts by mass of a methylene donor (D), 1.5 to 2.1 parts by mass of a thiuram based vulcanization accelerating agent (E), and 3.2 to 4.5 parts by mass of a sulfenamide based vulcanization accelerating agent (F), based on 100 parts by mass of a rubber component comprising 20 to 80% by mass of a modified conjugated diene based polymer (A),

• wherein the amounts of the thiuram based vulcanization accelerating agent (E) and the sulfenamide based vulcanization accelerating agent (F) mixed satisfy the following Expression (I):
• 0.45≤mass ratio[amount of thiuram based vulcanization accelerating agent (E) mixed/amount of sulfenamide based vulcanization accelerating agent (F) mixed]≤0.65 (I), and
• wherein the amounts of the filler (B) and the phenol resin (C) mixed satisfy the following Expression (II):
• 1.0≤[mass ratio{amount of phenol resin (C) mixed/amount of the filler (B) mixed}]×100≤4.0 (II).
