PROBLEM TO BE SOLVED: To provide a pneumatic tire by improving wet grip performance and low fuel consumption characteristic at good balance.SOLUTION: There is provided a pneumatic tire having a tread constituted by a rubber composition containing 100 pts.mass of a rubber component containing a styrene butadiene rubber of 40 to 100 mass% and a butadiene rubber of 0 to 60 mass%, 0.5 pt.mass or more of silica and 5 pts.mass or more of a resin, adhesive force measured by a predetermined adhesive force test method of the rubber composition is 300 or more when adhesive force of the standard rubber composition same with the exception that all amount of the resin is substituted by oil is 100 and a ratio of loss tangent at 0°C, tanδto loss tangent at 70°C, tanδof the rubber composition (tanδ/tanδ) of 3.0 to 10.SELECTED DRAWING: Figure 1

    【課題】ウェットグリップ性能および低燃費性がバランス良く改善された空気入りタイヤを提供すること。【解決手段】40〜100質量%のスチレンブタジエンゴムおよび0〜60質量%のブタジエンゴムを含むゴム成分100質量部に対し、シリカを0.5質量部以上、樹脂を5質量部以上含有するゴム組成物により構成されたトレッドを備えた空気入りタイヤであり、前記ゴム組成物の所定の粘着力試験方法により測定される粘着力が、樹脂全量をオイルに置き換えたこと以外は同じ基準ゴム組成物の粘着力を100とした場合に300以上であり、前記ゴム組成物の70℃での正接損失tanδ70℃に対する0℃での正接損失tanδ0℃の比(tanδ0℃/tanδ70℃)が3.0〜10である空気入りタイヤ。【選択図】図1
