Title:
A manufacturing method of a pneumatic tire and a pneumatic tire
Document Type and Number:
Japanese Patent JP6046951
Kind Code:
B2
Abstract:
A pneumatic tire has a rubber member constructed by a rubber ribbon winding body formed by spirally winding a rubber ribbon. The rubber ribbon includes a composite rubber ribbon which is formed by a non-conductive rubber, and a conductive rubber partly covering the non-conductive rubber. The composite rubber ribbon has a flat cross sectional shape and is gradually reduced in its thickness toward both ends. The conductive rubber has a cross sectional area which is equal to or less than 3% of a cross sectional area of the composite rubber ribbon, and forms a surface in one side and a surface in the other side in both ends of the composite rubber ribbon. The composite rubber ribbons that are adjacent in the width direction are partly overlapped, and a conductive route is provided by the conductive rubber connected between the composite rubber ribbons.
