摘要： A pneumatic tire comprising a silica-rich compound tread provided with an antistatic conductive rubber layer has improved safty based on durability and extrusion productivity. In this tire, the silica-rich compound rubber layer is divided at at least one portion in a width directional of the tire by a conductive rubber layer extended in a circumferential direction substantially over the whole thickness of said rubber layer. In this case, a thickness direction distance a in a width directional section of said rubber layer and an edge face length b of a divisional rubber layer consisting of said conductive rubber layer in a width directional section satisfy a relation formulated by the following expression, a

摘要： A pneumatic tire comprising a tread portion which comprises a surface rubber layer which is disposed in an outer portion of the tread portion in the radial direction of said tire and has a specific resistance of 108 &OHgr;·cm or more after curing by vulcanization and conductive rubber members which comprise a rubber composition having a specific resistance of 106 &OHgr;·cm or less and replace a portion of the surface rubber layer, wherein the conductive rubber members are disposed in portions of the surface rubber layer extending from the outer surface to the inner surface in the radial direction of said tire discontinuously in the circumferential direction of said tire at the outer surface of the surface rubber layer in the radial direction of said tire, is provided. The pneumatic tire shows not only an excellent effect of static discharge but also excellent durability.

摘要： A pneumatic radial tire for high-speed running vehicles has a directional tread pattern defined by one or two relatively wide circumferential grooves arranged in the central region and plural slant grooves arranged in each side region of the tread, and an aspect ratio of not more than 0.8. In this tire, the slant grooves are arranged in a herringbone form with respect to the equator without communicating with the circumferential groove, each of which extending from an initial end to a terminal end and being a folded line at a folding point corresponding to 0.3-0.45 times of the tread width that an inclination angle .alpha. of line segment inward from the folding point is 40.degree.-85.degree. with respect to the meridian of the tire and an inclination angle .beta. of line segment outward from the folding point is smaller than the inclination angle .alpha. and 0.degree.-50.degree. with respect to the meridian of the tire.
