Patent ID: 7766060

Claim:
A tire comprising at least one tread layer consisting of a tread rubber made of a low-conductive rubber and an electrically conductive band arranged in widthwise middle portion of the tread rubber and constituting at least a part of a conductive path from a belt to a treading face of a tread in which a first tread rubber portion of the tread rubber separated from a second tread rubber portion by the electrically conductive band is arranged so as to orient a side face thereof contacting with the electrically conductive band outward in the radial direction, and the electrically conductive band is made of a high-conductive thin annular rubber sheet and the high-conductive thin annular rubber sheet comprising a top part extending in a tire width direction on a top face of the first tread rubber portion, a bottom part extending in the tire width direction under a bottom face of the second tread rubber portion separated by the electrically conductive band and a middle part extending from an end of the top part in the width direction toward an end of the bottom part in the width direction, wherein the tread rubber is made of a low-conductive continuous rubber ribbon circumferentially wound plural times, and wherein at least two of the tread layers are arranged adjacent to each other inside and outside in the radial direction and the electrically conductive bands in the at least two of the tread layers are contacted with each other over the full periphery.
