    Abstract: A pneumatic tire includes at least two types of cap tread rubber layers made from differing rubber compositions disposed in a tread portion. A tan δ at 60° C. of a rubber composition forming the cap tread rubber layer on a vehicle outer side is greater than a tan δ at 60° C. of a rubber composition forming the cap tread rubber layer on a vehicle inner side. A ratio (tan δH/tan δL) of a maximum tan δH to a minimum tan δL at 60° C. of the tan δ of the rubber compositions forming the at least two types of cap tread rubber layers is from 1.05 to 1.80. An under tread rubber layer disposed in the tread portion has an average thickness from 0.8 mm to 4.0 mm. A hardness of a rubber composition forming the under tread rubber layer is from 73 to 83. A tan δ at 60° C. of the rubber composition forming the under tread rubber layer is 0.25 or less.

    Abstract: A heavy duty pneumatic tire comprises a carcass ply of steel cords turned up around a bead core in each bead portion so as to form a pair of turned up portions and a main portion therebetween. The steel cords of the carcass ply are rubberized with a topping rubber having a hardness Ht1 of from 68 to 90 degrees. The bead core is composed of: a bead core main made of windings of a steel wire; a rubber coating penetrating into the bead core main and having a hardness Hb of from 78 to 90 degrees; and a bead core wrapping layer surrounding the bead core main and composed of at least one ply of parallel organic fiber cords rubberized with a topping rubber having a hardness Ht2 of from 70 to 90 degrees. The fineness of each of the organic fiber cords of the bead core wrapping layer is in a range of from 940 to 4200 dtex. The distances between the organic fiber cords of the bead core wrapping layer is in a range of from 0.3 to 1.4 mm. The organic fiber cords of the bead core wrapping layer are inclined at an angle α1 in a range of from 20 to 70 degrees with respect to the tire circumferential direction. A minimum distance between the carcass cords and the axially innermost winding of the steel wire of the bead core main is in a range of from 0.8 to 3.0 mm.

    Abstract: A pneumatic tire comprises a carcass reaching a bead core of a bead portion from a tread portion via a side wall portion; a side wall rubber arranged in an outer side of said carcass and forming an outer side surface of said side wall portion; and a clinch rubber for preventing a rim displacement connected to a lower end of the side wall rubber and forming an outer side surface of said bead portion. The sidewall rubber and the clinch rubber are constituted by a strip wind body formed by winding and overlapping a side wall rubber strip and a clinch rubber strip in a circumferential direction and spirally, and the respective rubber strips are wound in the same direction from the bead portion side toward the tread portion side.
