To provide tire compositions which provide improved overall performance in terms of high-temperature grip performance and low-temperature grip performance, and tires including the tire compositions.SOLUTION: A tire composition contains an elastomer component, a filler, a cyclopentadiene resin, and an ester plasticizer. The cyclopentadiene resin is a hydrogenated dicyclopentadiene resin and/or a dicyclopentadiene-aromatic compound copolymer resin. The tire composition satisfies the following relationship: Elastomer component content≤Filler content.SELECTED DRAWING: None

    【課題】高温グリップ性能、低温グリップ性能の総合性能を改善できるタイヤ用組成物及びこれを用いたタイヤを提供することを目的とする。【解決手段】エラストマー成分と、充填剤と、シクロペンタジエン系樹脂と、エステル系可塑剤とを含み、前記シクロペンタジエン系樹脂は、水添ジシクロペンタジエン系樹脂及び/又はジシクロペンタジエン−芳香族化合物共重合樹脂であり、エラストマー成分量≦充填剤量、であるタイヤ用組成物。【選択図】なし
