1. A passenger road vehicle tire comprisinga carcass, a tread reinforcing breaker, a tread including an elongated tread strip of tire tread compound of high resistivity having a transverse width (TR), including silica as a reinforcement material and having a volume resistivity of approximately 1013 ohm-cm, a tire sub-tread being conductive underlying and in contact with the radially inner surface of the tread strip substantially across the entire transverse width (TR) and along the entire circumference of the inner surface of the tread strip, and at least one circumferentially extending conducting strip of low resistivity tire compound having a volume resistivity less than 108 ohm-cm, the width of each said at least one conducting strip being in the range of 5 to 25% of the tread width, and each of said at least one conducting strip extending between the radially outer surface of the tread strip and the tire sub-tread such that a conductive path is provided for dissipation of static electric charge from the tire through the sub-tread and conducting strip to the radially outer surface of the tread strip.
