Tire member and method for manufacturing the same

A method for manufacturing a tire member, comprising:

• preparing a premix comprising 100 parts by mass of a first diene rubber component, 0.1 to 0.5 parts by mass of a peptizer, and 0.2 parts by mass or more of a first thiosulfuric acid compound containing an amino group,
• preparing a mixture by kneading the premix with a second diene rubber component, an inorganic filler, and a second thiosulfuric acid compound containing an amino group, and
• mixing the mixture with a sulfur component and a vulcanization accelerator,
• wherein the mixture comprises 40% by mass or more of the first diene rubber component relative to a total diene rubber component in the mixture,
• wherein a temperature during mixing of the premix 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,
• wherein the first diene rubber component may be the same as or different from the second diene rubber component, and
• wherein the first thiosulfuric acid compound may be the same as or different from the second thiosulfuric acid compound.
