PROBLEM TO BE SOLVED: To provide a pneumatic tire with a good heat-dissipation property and its manufacturing method. SOLUTION: In this tire including a fiber-like heat-conductive filler at least in a tread part 1, the fiber-like heat-conductive filler is directed to a tire radial direction. In this tire, (1) a raw tire 7 including the fiber-like heat-conductive filler is molded at least in the tread part 1, and the raw tire 7 is vulcanized while a magnetic field and/or an electric field is applied from inside to outside in a radial direction of the raw tire 7. (2) When a plate-like rubber member 9 is extrusion molded using a rubber composite including the fiber-like heat-conductive filler, the plate-like rubber member 9 is extrusion molded while the magnetic field and/or the electric field is applied to the thickness direction of the plate-like rubber member 9. The plate-like rubber member 9 is arranged to the tread part to mold the raw tire and vulcanize the raw tire, so as to manufacture the tire. COPYRIGHT: (C)2006,JPO&NCIPI |
