Reifen mit einer Gummiseitenwand, die einen inneren leitenden Gummistreifen enthält

摘要

A pneumatic rubber tire (1) with a sidewall (5) having an outer visible layer (6) of a rubber composition of a relatively high electrical conductivity, wherein the tire sidewall (5) contains an internal rubber strip (7) of relatively high electrical conductivity. Said internal rubber strip (7) extends radially outward from a rubber chafer component (3) of the tire (1) to a tread base layer component (8) of a rubber tire tread (4) of a cap/base configuration, wherein said chafer and tread base rubber compositions are of a relatively high electrical conductivity. The rubber strip (7) thereby provides a path of increased electrical conductivity relative to said outer visible layer (6) of the tire sidewall (5) extending from the tire chafer (5) to the tread base layer tire components. In practice, the rubber strip is exclusive of the outer surface (10) of the tire tread cap layer intended to be ground-contacting, preferably exclusive of the tire tread cap layer itself, and preferably exclusive of the outer surface (3A) of the tire chafer component intended to contact a rigid metal rim of a tire/rim wheel assembly.
