Patent ID: 8376005

Claim:
A pneumatic tire comprising a side wall being in contact with a rim strip of a bead part, the side wall extending outward in a radial direction of the tire from the bead part and coupled to a ground contact edge region of the tread part, the side wall comprising a two-layer structure of an internal layer rubber and an external layer rubber; wherein on the circumference of one of two side parts of the tire, the rim strip, either the internal layer rubber or the external layer rubber of the side wall, and at least a surface part of the ground contact edge region are formed into a continuous conductive path by a conductive rubber material, the other of the internal layer rubber or the external layer rubber in the one side part comprises a non-conductive rubber material, in the other of the two side parts of the tire both the internal layer rubber and the external layer rubber of the side wall comprise a nonconductive rubber material, only the conductive path is used as a conducting path of the tire, and members other than the conducting path are selected from a conductive rubber material or a nonconductive rubber material; wherein the conductive rubber material is a rubber composition having electric resistivity less than 10 8 Ω·cm; and wherein the rubber composition comprises a diene rubber as a rubber component, and carbon black having a nitrogen adsorption specific area of from 25 to 100 m 2 /g in an amount of 14 vol % or more of the entire rubber composition.
