    Abstract: A pneumatic tire includes a low conductive rubber portion forming at least a cap rubber portion of the tread rubber which provides a tread surface of the tire. A narrow high conductive rubber strip extends in a radial direction of the tire at a widthwise center region of the cap rubber portion, and is exposed to the tread surface to form a discharge path for allowing electrostatic charges of a vehicle body to be discharged to a road surface. An unvulcanized tread rubber for the tire is obtained by passing a high conductive unvulcanized rubber through a passage extending from an extruder unit to the back side of an extrusion orifice, to form at least part of the remaining potion of the tread rubber. The high conductive unvulcanized rubber while passing through the passage is partly introduced into a narrow branch passage and passed through a slit-like opening having a cross-sectional shape which is substantially straight in a height direction of the extrusion head and situated in the vicinity of the back side of the extrusion orifice, to form the narrow strip of the high conductive rubber in a composite body of different kinds of unvulcanized rubbers.

    Abstract: The invention relates to a rubber tire composed of carbon black reinforced rubber carcass and having a rubber tread which is quantitatively reinforced with silica and contains a minor amount of carbon black reinforcement and/or carbon fibers. When said tread contains silica and carbon black reinforcement exclusive of carbon fibers, the said tread has a thin rubber layer over at least a portion of the outer surface tread intended to be ground-contacting wherein said rubber layer contains a combination of silica and/or carbon black reinforcement and carbon fibers. In one aspect, such alternative outer rubber layer (a) extends across at least a portion of the outer surface of the tread intended to be ground contacting and (b) contacts at least one other carbon black reinforced rubber component of the tire to provide a path of relatively low electrical resistance from said quantitatively silica reinforced tread to the bead portion of the tire carcass.

    Abstract: The tire of this invention has a silica-rich tread compound for excellent rolling resistance and tread wear properties. The tire is made to be conductive such that electrostatic charges on the vehicle can be quickly dissipated when the vehicle stops. An electrostatic discharge ring is located on at least one shoulder portion of the tire and has a relatively low volume resistivity, on the order of 100 megohm centimeter. The discharge ring is positioned to make contact with a conductive sidewall portion of the tire. The overall resistivity of the tire from the rim to the ground surface is made to be less than about 100 megohms.
