<p>A vulcanized pneumatic tire comprising a tread portion (1) which at least comprises a surface rubber layer (3) which is disposed in an outer portion of the tread portion in the radial direction of said tire and has a specific resistance of 10<8> OMEGA . cm or more after curing by vulcanization, and conductive rubber members (2) which are elongated in the circumferential direction and comprise a rubber composition having a specific resistance of 10<6> OMEGA . cm or less and with which portions of the tread portion are replaced, wherein the conductive rubber members (2) are made of a rubber that is different in type from the rubber of other portions of the tread portion (1), the conductive rubber members (2) are disposed in portions of the tread rubber portion (1) extending from a tire radial direction outer surface of the surface rubber layer to a tire radial direction inner surface of the tread rubber portion, and the conductive rubber members are formed discontinuously in both the tire circumferential direction and the tire widthwise direction at the outer surface of the surface rubber layer, and formed continuously in the tire circumferential direction but discontinuously in the tire widthwise direction at the inner surface of the tread portion. <IMAGE></p> |
