A pneumatic rubber tire with a sidewall having an outer visible layer of a rubber composition of a relatively high electrical conductivity, wherein the tire sidewall contains an internal rubber strip of relatively high electrical conductivity. Said internal rubber strip extends radially outward from a rubber chafer component of the tire to a tread base layer component of a rubber tire tread of a cap/base configuration, wherein said chafer and tread base rubber compositions are of a relatively high electrical conductivity. The rubber strip thereby provides a path of increased electrical conductivity relative to said outer visible layer of the tire sidewall extending from the tire chafer to the tread base layer tire components.
