| description | To provide a rubber composition for tires that has excellent damage resistance performance, and a tire that comprises a tire member composed of the rubber composition for tires.SOLUTION: Provided is a rubber composition for tires that contains a rubber component including an epoxidated diene rubber, an imidazole compound, and a divalent or higher carboxylic acid compound. When the elongation at break EB (%) and breaking strength TB (MPa) are measured in accordance with JIS K6251 using a 2-mm thick dumbbell-shaped test piece in compliance with ASTM D638 Type V, the EB repair rate (%) RREB and the TB repair rate (%) RRTB respectively satisfy (1) TB≥0.40, (2) RREB≥20 and (3) RRTB≥20, where RREB is a value defined by (EB (%) of a repaired test piece/EB (%) of an annealed test piece)×100, and RRTB is a value defined by (TB (MPa) of a repaired test piece/TB (MPa) of an annealed test piece)×100.SELECTED DRAWING: None
【課題】耐外傷性能に優れたタイヤ用ゴム組成物および当該タイヤ用ゴム組成物からなるタイヤ部材を備えたタイヤを提供すること。【解決手段】エポキシ化ジエン系ゴムを含むゴム成分と、イミダゾール化合物と、２価以上のカルボン酸化合物とを含み、厚さ２ｍｍのＡＳＴＭＤ６３８ＴｙｐｅＶに準拠したダンベル形状の試験片について、ＪＩＳＫ６２５１に準じて破断時伸びＥＢ（％）および破断強度ＴＢ（ＭＰａ）を測定するとき、修復試験片のＥＢ（％）／アニール試験片のＥＢ（％）×１００で定義される値であるＥＢ修復率（％）ＲＲEB、および修復試験片のＴＢ（ＭＰａ）／アニール試験片のＴＢ（ＭＰａ）×１００で定義される値であるＴＢ修復率（％）ＲＲTBが、それぞれ、（１）ＴＢ≧０．４０、（２）ＲＲEB≧２０、（３）ＲＲTB≧２０を満たすタイヤ用ゴム組成物。【選択図】なし |
