PROBLEM TO BE SOLVED: To provide a tread rubber composition for two wheeled vehicle tire capable of improving grip performance (especially wet grip performance), chipping resistance in a good balance and a two-wheeled vehicle tire using the rubber composition for a tread of the tire.SOLUTION: The invention relates to a tread rubber composition for two wheeled vehicle tire containing a rubber composition containing styrene-butadiene rubber and a structured silica having an average length Wof branched particles Z-Z containing branched particle Z of 30 to 400 nm of 5 to 50 pts.mass based on 100 pts.mass of the rubber composition, where the branched particle Z is a particle neighboring 3 particles.

    【課題】グリップ性能(特に、ウェットグリップ性能)、耐チッピング性能をバランス良く向上できる二輪車タイヤ用トレッドゴム組成物、及び該ゴム組成物をタイヤのトレッドに用いた二輪車タイヤを提供する。【解決手段】スチレンブタジエンゴムを含むゴム成分と、1つの粒子に対して隣接する粒子が3つ以上の粒子を分岐粒子Zとしたとき、分岐粒子Zを含む分岐粒子間Z−Zの平均長W1が30〜400nmのストラクチャーシリカとを含み、前記ゴム成分100質量部に対して、前記ストラクチャーシリカを5〜50質量部含む二輪車タイヤ用トレッドゴム組成物に関する。【選択図】図2
