A masterbatch contains 13 parts by mass or more and 130 parts by mass or less of hydrophilic fumed silica, and 1 part by mass or more and 40 parts by mass or less of a silane coupling agent, with respect to 100 parts by mass of a diene-based rubber. A rubber composition for a tire contains 5 parts by mass or more and 90 parts by mass or less of hydrophilic fumed silica, and 1.5 parts by mass or more and 30 parts by mass or less of a silane coupling agent, with respect to 100 parts by mass of a diene-based rubber. A method for producing a masterbatch includes kneading a diene-based rubber, hydrophilic fumed silica, and a silane coupling agent.
