Document Type and Number:
Japanese Patent JP7256649
Kind Code:
B2
Abstract:
To provide a pneumatic tire and a manufacturing method for the same, in which a ribbon method is used and a conductive path from a bead part to a shoulder part is secured.SOLUTION: A pneumatic tire AT comprises: a tread part 7; shoulder parts 8 arranged at both outsides in a tire width direction TW adjacently to the tread part 7; a side wall part 9, disposed adjacently to the shoulder parts 8, which is formed of dual side rubbers 12 in which core materials 12a made of non-conductive rubber in a ribbon shape are partially coated with coating materials 12b made of conductive rubber in a film shape; and a bead part 10 arranged adjacently to the side wall part 9. Further the pneumatic tire AT is provided with a conductive path in which members with conductivity are constituted continuously from the bead part 10 to the shoulder part 8. In the side wall part 9, the dual side rubbers 12 are wound around spirally, and the coating materials 12b of the dual side rubbers 12 adjacent to each other in a tire meridian cross section overlap with each other to constitute the conductive path.SELECTED DRAWING: Figure 5
