To provide a pneumatic tire that retains wet steering stability and rolling resistance performance and exhibits higher conducting performance.SOLUTION: In a tire meridian sectional view under an unloaded condition with a tire incorporated in a normal rim and a normal internal pressure applied, a conducting rubber (20a) is formed in a region (RS) other than a region (RC) whose width shares 5% of that of a swelled land part centered on a swell apex position (PA) at which the swelled land part (20) most greatly swells outward in a tire radial direction.SELECTED DRAWING: Figure 1
【課題】ウェット操縦安定性能や転がり抵抗性能を維持しつつ、さらに導電性能を高めた空気入りタイヤを提供すること。【解決手段】正規リムに組んで正規内圧を付与した無負荷状態におけるタイヤ子午断面視で、膨出陸部(20)のタイヤ径方向外側に最も膨出した膨出頂点位置(PA)を中心とした膨出陸部の5%幅の領域(RC)を除く領域(RS)に、導電性ゴム(20a)が形成されている。【選択図】図1
