A rubber composition for tire, which combines low heat build-up properties and breakage property, reduces fuel consumption of a tire, and has excellent good processability is provided. The rubber composition for tire is obtained by blending sulfur and caprolactam disulfide with a diene rubber component to obtain a pre-mixture which does not contain a reinforcing filler and a vulcanization accelerator, and blending and mixing a reinforcing filler and a vulcanization accelerator with the pre-mixture in a post-mixing step.
