PNEUMATIC TIRE AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of combining grounding performance and durability, and its production method. SOLUTION: The pneumatic tire 1 includes a belt layer 4 arranged outside in the tire diameter direction of a carcass layer 3 and a tread rubber 5 arranged outside in the tire diameter direction of the belt layer 4. The tread rubber 5 is composed by laminating a cap rubber layer 51 made of a poor-conductive rubber material and composing a tread surface and a base rubber layer 52 made of high-conductive rubber material. A filament conductor 53 is arranged penetrating through the cap rubber layer 51 from an outer surface of a tread part to the base rubber layer 52 and conductively contacting the base rubber layer 52 without penetrating through the base rubber layer 52.
