    • A pneumatic tire formed by using a rubber composition comprising a vulcanization accelerator represented by the following general formula: wherein R1 represents a hydrogen atom, an alkyl group, or an aryl group, and R2 represents an alkyl group or an aryl group when R1 represents a hydrogen atom, and represents a hydrogen atom, an alkyl group, or an aryl group when R1 represents an alkyl group or an aryl group, in an amount of 0.2 to 8.0 parts by weight per 100 parts by weight of a rubber component. A pneumatic tire which maintains low rolling resistance and is improved to prevent resistance to ply-end separation throughout the entire term of tire use, a pneumatic tire which shows excellent controllability and durability in the last stage of tire use, and a pneumatic tire which prevents heat aging of belt layers and a decrease in the adhesion of steel cord with a rubber composition and shows excellent durability are provided.
    • 一种充气轮胎,其特征在于,使用由以下通式表示的硫化促进剂的橡胶组合物形成的充气轮胎:其中,R1表示氢原子,烷基或芳基,R2表示烷基或芳基, 氢原子,当R 1表示烷基或芳基时,表示氢原子,烷基或芳基,相对于100重量份橡胶成分为0.2〜8.0重量份。气动 保持低滚动阻力的轮胎,并且改进以防止在整个轮胎使用期间对帘布层分离的阻力,在轮胎使用的最后阶段显示出优异的可控制性和耐久性的充气轮胎以及防止热老化的充气轮胎 的带层,并且提供了具有橡胶组合物的钢帘线的附着力降低并且显示出优异的耐久性。
