Abstract
The invention relates to a rubber tire having a rubber tread intended to be ground-contacting which is relative electrically insulating and which has at least one thin, narrow, carbon black reinforced rubber strip integral the outer surface, or face, of said tread, each strip extending laterally across the tread to each of the tire's carbon black reinforced sidewalls. In one aspect, said outer rubber strip, extends laterally across the outer surface of the tread which is designed to be ground contacting and connects with carbon black reinforced tire sidewalls to provide a path of reduced electrical resistance from the outer surface of the tire tread to the bead portion of the tire carcass and, thereby, such a reduced electrical resistance path from a vehicle to the road surface. In another aspect, the said rubber tread intended to be ground-contacting, is primarily reinforced with silica.
