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.
Pneu en caoutchouc possédant une bande de roulement de caoutchouc, destinée à entrer en contact avec le sol, qui démontre une isolation électrique relative et qui est pourvue d'au moins un ruban mince et étroit de caoutchouc renforcé de noir de carbone recouvrant intégralement la surface extérieure ou la face de ladite bande. Chaque ruban s'étend latéralement en travers de la bande entre les flancs renforcés de noir de carbone du pneu. Selon une application de cette invention, le ruban de caoutchouc extérieur s'étend latéralement en travers de la surface extérieure de la bande qui est conçue pour entrer en contact avec le sol et se joint aux flancs renforcés de noir de carbone, afin de créer un trajet de résistance électrique réduite de la surface extérieure de la bande de roulement au talon de la carcasse du pneu et, de ce fait, du véhicule à la couche de roulement. Selon une autre application, ladite bande de roulement destinée à entrer en contact avec le sol est essentiellement renforcée de silice.
