Abstract
A preparation method of a rubber composition for a tire assures that good processability can be obtained even if a silane coupling agent having a mercapto group is blended. The preparation method of a rubber composition for a tire is characterized by initiating kneading of a rubber component and a specific polysulfide compound before kneading the rubber component and a silane coupling agent having a mercapto group.
