The poorly conducting tread rubber has an embedded, circumferentially-surrounding radial film layer. This contacts the road and e.g. reinforcement or other radially inner conductive portions of the tire. The film layer and portions have a specific resistance below 10<8> ohm.cm (i.e. they are good conductors in terms of static electricity potentials). The film layer is formed during manufacture, by...
