Pneumatic tire with conical or wedge-shaped plugs and method of manufacturing same.

摘要

A plurality of conductive rubber members (20) each having an electric resistance value lower than that of a tread rubber body (11a) is embedded in the tread rubber body (11a) from a peripheral surface of the tread rubber body (11a) at predetermined intervals in a circumferential direction of a pneumatic tire (10). An outer end surface (20a) of each of the conductive rubber members (20) in the radial direction of the pneumatic tire (10) is exposed on a peripheral surface (11c) of a tread part (11). An inner end (20b) of each of the conductive rubber members (20) in the radial direction is brought into contact with a steel belt layer (15) formed at an inward position of the tread part (11) in the radial direction or with a conductive rubber layer (11b) formed between the tread rubber body (11a) and the steel belt layer (15).
