Abstract
Provided is a rubber composition for a tire having improved abrasion resistance, fuel economy and processability in a balanced manner. Also provided is a method for producing the rubber composition, and a pneumatic tire formed from the rubber composition. The rubber composition for a tire is obtained by mixing a kneaded mixture containing butadiene rubber, silica, a silane coupling agentwith a sulfur content of 20% by mass or more, and oil; styrene-butadiene rubber; and a silane coupling agentwith a sulfur content of less than 20% by mass.
