    摘要： The invention provides a base tire manufacturing method and a base tire having a proper thickness for the rubber layer by setting the thickness of the rubber layer in such a manner as to optimize the buffing allowance for the cure-molded base tire without placing limits on the shape of the post-buffing base tire. The base tire thus manufactured has a belt layer, an outermost rubber layer of a predetermined width disposed over the belt layer for application of a tread therto, and edge rubber members at both axial ends of the outermost rubber layer. For this base tire, the loss tangent of the outermost rubber layer is set lower than the loss tangent of the edge rubber members, the pre-buffing thickness A1 at the equator of the outermost rubber layer is set at “post-buffing thickness A2×150%” or less, and the post-buffing thickness A2 is set in a range of 1 mm to 3.5 mm.

    摘要： 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.
