The present invention provides a rubber composition for a tire that has low heat build-up, excellent elongation at break and crack resistance after initial aging, crack resistance, and ozone resistance, and a pneumatic tire using the same. 15 to 70 parts by mass of carbon black having a nitrogen adsorption specific surface area (N 2 SA) of 30 m 2 / g or more and less than 80 m 2 / g with respect to 100 parts by mass of a diene rubber containing natural rubber and / or isoprene rubber. The rubber composition for tires which mix | blends 0.5-10 mass parts of phenol derivatives represented by a part and following formula 1. A pneumatic tire using the tire rubber composition for a belt cushion (8), an upper bead filler (62), and a sidewall (2). [Selection] Figure 1 |
