    摘要: This invention provides a pneumatic tire having its weight reduced without degrading the durability of bead portions.
    Provided is a pneumatic tire comprising, as a framework, at least one carcass ply comprising a steel cord covered with rubber. Letting d (mm) be the cord diameter of the steel cord and T (MPa) be the tensile strength of a steel filament forming the steel cord, the following relation is satisfied: a 1 T − b 1 > d > a 2 T + b 2 (where a 1 is 3.65 × 10 -4 mm/MPa, b 1 is 0.42 mm, a 2 is -8.00 × 10 -5 mm/MPa, and b 2 is 0.78 mm), and the tensile strength T of the steel filament is 3000 MPa (exclusive) to 4000 MPa (exclusive) and the number of hits E under a bead core of the steel cord in the carcass ply is 12 hits/25 mm (exclusive) to 38 hits/25 mm (exclusive).

    摘要: Provided is a pneumatic tire in which basic performances needed for a side portion can be satisfied without compromising a light weight effect due to decrease in the gauge of the side portion.
    Provided is a pneumatic tire which is composed of a pair of bead portions 11, a pair of side wall portions 12 extending from the pair of bead portions, and a tread portion 13 bridging both side wall portions and which comprises one or more carcasses 2 extending toroidally between the pair of bead portions. The carcass 2 is constituted of a treat which is an organic fiber cord coated with rubber; the occupancy rate of the organic fiber cord in the treat is 70% or higher; and the ratio of the cord diameter ϕ (mm) of the organic fiber cord as a dip treated cord to the minimum value D (mm) of the gauge in the thickness direction of the tire at an external region of the side wall portion in the tire radial direction from the maximum width portion of a tire when the tire is mounted to a rim satisfies the relationship represented by the expression below:

    摘要: A radial ply pneumatic tire (10) has carcass plies (13 to 18), reinforced by nylon monofilaments and folded axially around a pair of laterally spaced bead cores (11, 12), belt plies 31 to 38), reinforced by nylon monofilaments and at least one layer (60 to 62), comprising a spirally wound, nylon reinforced strip, extending across the belt width and interposed between the belt plies (31 to 38) and the tire tread (40). In a preferred embodiment, which is suitable for use on an aircraft, the tire has several turn-up (15 to 18) and turn-down (13, 14) carcass plies as well as strips (65, 66), reinforced by nylon cords, interposed between the turn-up and turn-down plies near the bead cores.
