RUBBER COMPOSITION FOR TIRES, AND PNEUMATIC TIRE

Provided are a rubber composition for tires, capable of improving discoloration resistance and tire appearance while maintaining good handling stability, crack resistance, and ozone resistance or improving these properties, and a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for tires including a rubber component having a combined amount of polybutadiene rubber, natural rubber, and polyisoprene rubber of 90% by mass or more based on 100% by mass of a rubber component; sulfur; a pluronic nonionic surfactant in an amount of 0.1 to 5.0 parts by mass per 100 parts by mass of the rubber component; and carbon black in an amount of 2 to 70 parts by mass per 100 parts by mass of the rubber component.
