To provide a tire using a tread rubber of a two-layer structure comprising a non-conductive rubber and a conductive rubber, having superior electrical conductivity and having no wavy wear or exfoliation by improving an arrangement or a shape of a conductive part penetrating a cap rubber layer.

In this tire, a tread rubber 1 has a two-layer structure comprising a non-conductive cap rubber layer 11 on the tire tread face side and a conductive base rubber layer 12 on the inner side. A bar-like protrusion 6 having a relatively small cross section wherein a rubber 11a of the cap rubber layer 11 covers the peripheral side face of a rubber part 12a extending from a tread lower layer part to the tire tread face side and extending from the base rubber layer 12 is formed in a ground contact face area of the tread rubber 1 such that the tip surface of the protrusion 6 is positioned in a nearly same level as a land part 5 surface with an air space formed around the bar-like protrusion 6 in a groove or the land part 5, while the rubber part 12a on the inner side is exposed at the tip surface.
