PROBLEM TO BE SOLVED: To provide a pneumatic tire for winter having improved rolling resistance (low fuel consumption), brake force on snow ice (snow ice performance) and wear resistance in a well balance at high productivity.SOLUTION: Provided is a pneumatic tire for winder having a tread produced using a rubber composition. The rubber composition contains a rubber component, silica, a silane coupling agent having mercapto groups and a specified polysulfide compound and is obtained by kneading the polysulfide compound in the step former than the kneading step of a vulcanization chemical.
【課題】 ウェットグリップ性能を維持又は改善しつつ、転がり抵抗(低燃費性)、雪氷上での制動力(雪氷上性能)、耐摩耗性をバランス良く改善した冬用空気入りタイヤを生産性良く提供する。【解決手段】 ゴム組成物を用いて作製したトレッドを有する冬用空気入りタイヤであって、該ゴム組成物は、ゴム成分、シリカ、メルカプト基を有するシランカップリング剤、及び、特定のポリスルフィド化合物を含み、加硫薬品の混練工程より前の工程において、該ポリスルフィド化合物を混練して得られることを特徴とする冬用空気入りタイヤ。【選択図】なし
