PROBLEM TO BE SOLVED: To solve the problem in which: it is difficult to improve on-ice performance and wet performance at the same time, although many means are proposed in order to improve the on-ice performance of studless tires.SOLUTION: The problem is solved by a studless tire rubber composition that comprises a diene rubber of 100 pts.mass, with the diene rubber comprising a natural rubber and a butadiene rubber and having an average glass transition temperature of -70°C or less, and a fluorine rubber of 1-30 pts.mass, with the fluorine rubber having a water contact angle of 93 degrees or more.SELECTED DRAWING: None

    【課題】従来、スタッドレスタイヤの氷上性能を向上させるために多くの手段が提案されているが、氷上性能およびウェット性能を同時に高めることは困難であった。【解決手段】天然ゴムおよびブタジエンゴムを含む平均ガラス転移温度が−70℃以下のジエン系ゴム100質量部に対し、水に対する接触角が93度以上のフッ素ゴムを1〜30質量部配合してなることを特徴とするスタッドレスタイヤ用ゴム組成物によって、前記課題を解決した。【選択図】なし
