RUBBER COMPOSITION FOR TIRES AND PNEUMATIC TIRES

The present invention provides a rubber composition for a tire excellent in grip performance on ice, abrasion resistance, and handling stability, and a pneumatic tire formed therefrom. The present invention relates to a rubber composition for a tire including, per 100 parts by mass of a rubber component: 10 to 150 parts by mass of silica and 10 to 30 parts by mass of a diene rubber gel that contains a hydroxy group and has a glass transition temperature of -40°C to 0°C, the rubber component including, based on 100% by mass of the rubber component: (a) 30 to 90% by mass of butadiene rubber and (b) 10 to 60% by mass of a diene rubber that is other than the butadiene rubber (a) and has a glass transition temperature of -60°C or lower.
