description PROBLEM TO BE SOLVED: To provide a method for producing a rubber foam for a tire, for easily molding a rubber foam having open cells.SOLUTION: The method comprises: molding an unvulcanized tire by using an unvulcanized rubber sheet which is prepared by molding a rubber composition containing 10 to 150 parts by weight of a filler, 10 to 150 parts by weight of water-soluble fine particles and 0.5 to 20 parts by weight of a chemical foaming agent based on 100 parts by weight of a diene rubber; vulcanizing and molding the unvulcanized tire at a temperature equal to or higher than the decomposition temperature of the chemical foaming agent; and then dissolving and removing the water-soluble fine particles to form the open cells.
