CONDUCTIVITY PATH FOR NON-CONDUCTIVE TIRE TREAD

摘要

A pneumatic tire constructed with an electrically conductive tire tread (138) that defines a channel (148) extending radially inward through a tread base rubber (134) having a relatively high electrical resistivity so as to provide a conductivity path to a belt layer (128) within the tire. In certain embodiments, a conductivity path (146) extending from the belt layer (124) through a belt cushion section (122) to a carcass section (112) of the tire is also provided.
