RUBBER COMPOSITION

The present invention provides a rubber composition having excellent processability, tensile strength at break, and fuel economy performance. An embodiment of the present invention is a rubber composition for a tire, the rubber composition containing a diene rubber, silica, and a non-ionic surfactant represented by Formula (1) below (in Formula (1), b is from 5 to 45, and a + c is from 55 to 95), a content of the silica being from 50 to 200 parts by mass per 100 parts by mass of the diene rubber, and a content of the non-ionic surfactant being from 0.1 to 15 mass% with respect to the content of the silica.
