Abstract: A pneumatic tire having improved conductivity is disclosed herein whereby the tire is provided with at least one conductive pathway extending through the tread surface and contacting the tread cushion. Conductive pathways are created by introducing small volumes of high carbon black concentration. Such pathways provide low electrical resistance and dissipation of static charge accumulation on a motor vehicle.
