PROBLEM TO BE SOLVED: To provide a pneumatic tire having an outer peripheral tread having a tread travel surface.SOLUTION: A pneumatic tire having an outer peripheral tread contains a peripheral direction tread composition containing a reinforcement filler which contains unique combination of solution-prepared and emulsion-prepared styrene/butadiene elastomer, and a specific combination of a plurality of traction promotion resins and selected carbon black and preliminarily hydrophobized precipitated silica, where the traction resin contains a polyester phthalate resin, a styrene/alpha-methylstyrene resin, gum rosin and a coumarone-indene resin, and the preliminarily hydrophobized precipitated silica is treated with at least one of alkoxy organic mercaptosilane and bis(3-trialkoxysilyl organic) polysulfide (containing 2 to 4 connection sulfur atoms in the polysulfide bridge on the average).SELECTED DRAWING: None

    【課題】トレッド走行面を有する外周トレッドを有する空気入りタイヤの提供。【解決手段】溶液調製及びエマルション調製されたスチレン/ブタジエンエラストマーの独自組合せ、複数のトラクション促進樹脂、及び選択されたカーボンブラックと予備疎水化沈降シリカの特定の組合せを含有する補強フィラーを含有する周方向トレッド組成物を有する空気入りタイヤであり、前記トラクション樹脂が、ポリエステルフタレート樹脂、スチレン/アルファメチルスチレン樹脂、ガムロジン及びクマロンインデン樹脂を含み、前記予備疎水化沈降シリカが、アルコキシ有機メルカプトシラン及びビス(3−トリアルコキシシリル有機)ポリスルフィド(そのポリスルフィド橋中に平均2〜4個の連結硫黄原子を含有する)の少なくとも一つで処理された沈降シリカである外周トレッドを有する空気入りタイヤ。【選択図】なし
