PROBLEM TO BE SOLVED: To provide a method for manufacturing a tire member having high abrasion resistance.SOLUTION: There is provided a method for manufacturing a tire member which comprises: (i) a step of mixing carbon black, a dispersion solvent and a rubber latex solution to produce a carbon black-containing rubber latex solution; (ii) a step of coagulating the carbon black-containing rubber latex solution to produce a carbon black-containing rubber coagulated product; (iii) a step of dehydrating the black-containing rubber coagulated product to produce a rubber wet master batch while adding a compound exemplified by sodium (2Z)-4-[4-aminophenyl)amino]-4-oxo-2-butenoate containing an alkali metal salt structure of an amino group, a benzene ring, an amide group, an alkenyl group and carboxylic acid to the carbon black-containing rubber coagulated product and dispersing the compound in the carbon black-containing rubber coagulated product containing moisture; and (iv) a step of adding carbon black and the compound to the rubber wet master batch, followed by dry-mixing.SELECTED DRAWING: None
