The rubber composition contains a rubber component, sulfur, and a molten mixture of a solid resin and a plasticizer. The solid resin has an SP value of 9.2 to 13 and/or a softening point of 130°C or greater, and the plasticizer contains at least one compound selected from the group consisting of phosphoric acid esters, phthalic acid esters, aliphatic polybasic acid esters, trimellitic acid esters, acetic acid esters and ricinoleic acid esters. The rubber composition contains at least 1 part by mass of the solid resin per 100 parts by mass of the rubber component. |
