PROBLEM TO BE SOLVED: To provide a tire rubber composition where colorfastness and tire appearance can be improved while good fuel efficiency, abrasion resistance, and on-ice performance are maintained or improved, and a pneumatic tire using the tire rubber composition.SOLUTION: The present invention relates to a tire rubber composition including 0.1-6.0 parts by mass of a nonionic surfactant represented by formula (1) and/or ester of the formula (1) with respect to 100 parts by mass of rubber components, and including sulfur and a total content of at least 70% by mass of butadiene rubber, natural rubber, and isoprene rubber in 100% by mass of rubber components. In the formula (1), Rrepresents a 6-26C hydrocarbon group and d represent any integer.
【課題】良好な低燃費性、耐摩耗性、氷上性能を維持又は改善しつつ、耐変色性、タイヤの外観を改善できるタイヤ用ゴム組成物、及びこれを用いた空気入りタイヤを提供する。【解決手段】ゴム成分100質量部に対して、下記式(1)及び/又は下記式(1)のエステルで表される非イオン界面活性剤を0.1〜6.0質量部含み、ゴム成分100質量%中、ブタジエンゴム、天然ゴム、及びイソプレンゴムの合計含有量が70質量%以上であり、硫黄を含むタイヤ用ゴム組成物である。(式(1)中、R1は、炭素数6〜26の炭化水素基を表す。dは任意の整数を表す。)【選択図】なし
