    Abstract: In a method for forming a green tread rubber comprised of a cap rubber layer which outer surface forms a tread surface and a base rubber layer that adjoins the same inside thereof in the radial direction, a cap rubber having a rubber component of styrene/butadiene rubber or being a mixed rubber of natural rubber and butadiene rubber is used as the cap rubber layer. The base rubber layer is formed as an annular body in which a strap-like rubber extruded body of wide width, which is extruded from a rubber extruder and is cut into constant size, is wound around a molding drum by a single round with their end portions in a circumferential direction being joined with each other. The cap rubber layer is formed as a strip layered body in which a long strap-like rubber strip of narrow width, which is extruded from an rubber extruder, is successively wound by overlapping the same on the annular body in the circumferential direction and in a spiral manner. A thickness T2 of the base rubber layer on a tire equator is defined to be 0.05 to 0.7 times a thickness T0 of the green tread rubber on the tire equator.

    Abstract: A pneumatic tire comprises a carcass ply extending between bead portions and is turned up around a bead core in each bead portion to form two turnup portions and a main portion therebetween; each of the turnup portions extends radially outwardly and adjoins the main portion from a certain height above the bead core; a space is surrounded by the carcass ply main portion, and each turnup portion and the bead core is filled with a small size bead apex rubber or a gas; and the bead portion is provided between the carcass ply and the bead core with a bead core cover for preventing the carcass cords from direct contacting with the bead core.

    Abstract: A tread rubber G has a short-fiber-mixed rubber portion 10 forming a grounding surface. In a region Y1 between an outer grounding end Eo and a tire equator C located outside of a vehicle when a tire is mounted to the vehicle, the short fibers f are inclined and oriented at an angle α outward of the vehicle radially outward of the tire, and an angle α1 of the short fibers f in the outer grounding end Eo is greater than an angle α2 of the short fibers f in the tire equator C.
