Rubber composition for tire, and pneumatic tire

The present invention provides a rubber composition for a tire having improved abrasion resistance, fuel economy and processability in a balanced manner. The present invention also provides a method for producing the rubber composition, and a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for a tire obtained by mixing a kneaded mixture containing butadiene rubber 1, silica 1, a silane coupling agent 1 with a sulfur content of 20% by mass or more, and oil 1; styrene-butadiene rubber 2; and a silane coupling agent 2 with a sulfur content of less than 20% by mass.
