    摘要： A pneumatic tire includes: at least one carcass layer 4A, 4B bridging between a pair of beads 3 and 3; and a belt layer 7A, 7B with a plurality of layers, the belt layer being disposed at an outer peripheral side of the carcass layer 4A, 4B in a tread 1. In a case where a shoulder-equivalent region X is defined as a region between a position P2 at a peripheral length of 20 mm along a tire's meridional cross-section heading from a belt-edge corresponding position P1 on a tire inner surface S corresponding to an edge of a broadest belt layer 7A toward a bead-toe side and the belt-edge corresponding position P1, a rubber portion interposed between a carcass cord C included in the carcass layer at an innermost side and the tire inner surface S has a thickness t of equal to or less than 1 mm at least in the shoulder-equivalent region X, and the rubber portion is formed by a rubber composition mainly including a diene rubber. Accordingly, a pneumatic tire and a method for manufacturing the tire, which makes it possible to prevent rupturing of a carcass cord, even with the side rigidity having been increased, thus improving the durability, can be provided.

    摘要： There is provided a pneumatic bias tire capable of preventing a separation failure between carcass plies in the bending deformation of a tire side portion under an action of a high load. In a heavy duty pneumatic bias tire having a ply rating of not less than 58 and an aspect ratio of not more than 80%, a rubber volume as the product of a distance between ply cords in the carcass ply and a distance between ply cords of mutually adjoining carcass plies with respect to three or more inside carcass plies of an innermost carcass ply group in at least a portion corresponding to a position of a maximum tire width is 500-1350 mm 3 .

    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 (tan ´) of the outermost rubber layer is set lower than the loss tangent (tan ´) 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 X 150%" or less, and the post-buffing thickness A2 is set in a range of 1 mm to 3.5 mm.
