To provide a rubber composition for studless tires that demonstrates excellent processability and achieves improved on-ice performance while maintaining at least the heat build-up and wear resistance.SOLUTION: This rubber composition for studless tires contains 20 pts.mass or more of an inorganic filler relative to 100 pts.mass of a diene rubber that has an average glass transition temperature of -80°C or less, and also contains more than 0 mass% less than 10 mass% of a whisker-like basic metal salt (A) relative to the inorganic filler.SELECTED DRAWING: None
【課題】発熱性および耐摩耗性を少なくとも維持しつつ、加工性に優れ、氷上性能を向上させ得るスタッドレスタイヤ用ゴム組成物を提供する。【解決手段】平均ガラス転移温度が-80℃以下のジエン系ゴム100質量部に対し、無機充填剤を20質量部以上配合し、かつウィスカ状の塩基性金属塩(A)を前記無機充填剤に対し0質量%を超え10質量%未満配合してなるスタッドレスタイヤ用ゴム組成物によって上記課題を解決した。【選択図】なし
