Abstract

See full text

A method for producing a tire sidewall rubber member according to an embodiment comprises: a first kneading step of preparing a first kneaded product by kneading a diene rubber, carbon black, a compound represented by formula (I) (wherein R1 and R2 represent a hydrogen atom, an alkyl group, an alkenyl group or an alkynyl group, and M+ is Na+, K+ or Li+), and zinc oxide; and a second kneading step of adding wax and/or stearic acid to the first kneaded product, followed by kneading. Thus, low heat generation properties are improved while suppressing the deterioration of tear resistance.
