PROBLEM TO BE SOLVED: To provide sufficient anti-static effect, excellent safety from the point of view of endurance and high extrusion productivity. SOLUTION: In a pneumatic tire wherein a rubber layer, in which a lot of silica are combined at least in the surface of a tread 1, is provide and the rubber layer is separated by the conductive separation rubber layer 2 extending in the peripheral direction ranging substantially the whole thickness of the rubber layer in the width direction of the rubber layer 2 in at least one place in the width direction of the tire, the distance (a) in the thickness direction in the width directional cross section of the rubber layer and the length (b) of the edge face of the width directional cross section of the separation rubber layer separated by the conductive separation rubber layer 2 satisfy the relation expressed by a<b. |
