Abstract
Official abstract text for this publication.
In the invention, at least a tire outer circumferential side portion of a tread portion is formed of a non-conductive rubber layer. The non-conductive rubber layer is formed by winding and laminating a non-conductive rubber ribbon along a tire circumferential direction. A conductive layer is provided on an outer circumference of the non-conductive rubber ribbon, and the conductive layer continuously and spirally extends along the tire circumferential direction, and is exposed on a tread surface from a bottom surface of the non-conductive rubber layer toward a tire outer circumferential side. Accordingly, an electricity generated in a vehicle body is discharged to a road through the conductive layer. Since the conductive layer is scattered within the non-conductive rubber layer and exposure on the tread surface is preferably secured, it is possible to achieve an excellent conductivity.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pneumatic tire comprising: a non-conductive rubber layer constructing at least a tire outer circumferential side portion of a tread portion and formed by winding and laminating more than one non-conductive rubber ribbon along a tire circumferential direction; and a conductive layer provided in a part of the non-conductive rubber ribbon and continuously and spirally extending along the tire circumferential direction and spirally extending around a r…
