A method for manufacturing a tire member, containing a step (A) for producing a mixture containing a diene rubber component, an inorganic filler, a peptizer and a thiosulfuric acid compound containing an amino group, and a step (B) for mixing the mixture, a sulfur component and a vulcanization accelerator, wherein a tire member having improved abrasion resistance, tear strength and flex fatigue resistance is obtained, and the tire member are provided. A premix containing 100 parts by mass of the diene rubber component, from 0.1 to 0.5 parts by mass of the peptizer and 0.2 parts by mass or more of the thiosulfuric acid compound containing an amino group, obtained under a condition in which a temperature during mixing is maintained within a range of from 145 to 170° C. for 20 seconds or more and a temperature at completion of the mixing is 170° C. or lower.
