To solve the problem in which: an all-season pneumatic tire should have steering stability (dry grip performance) on a dry road surface during high speed driving and steering stability (wet grip performance) on a wet road surface and, besides, should have low temperature performance such as steering stability (low temperature grip performance) at low temperature and on a snow-covered road surface.SOLUTION: A rubber composition contains, based on 100 pts.mass of a rubber component containing 30-60 pts.mass of butadiene rubber, 70-120 pts.mass of silica and 1-25 pts.mass of polyethylene glycol bis(2-ethylhexanoate).SELECTED DRAWING: None

    【課題】オールシーズン用の空気入りタイヤは、高速走行時における乾燥路面での操縦安定性(ドライグリップ性能)や湿潤路面での操縦安定性(ウェットグリップ性能)を具備することの他に、低温時や積雪路面での操縦安定性(低温グリップ性能)などの低温性能を具備することが必要である。【解決手段】ブタジエンゴムを30〜60質量部含むゴム成分100質量部に対し、シリカを70〜120質量部およびポリエチレングリコールビス(2−エチルヘキサノエート)を1〜25質量部配合してなるゴム組成物によって上記課題を解決した。【選択図】なし
