摘要： Provided is a tire such that both tire weight reduction and high durability can be achieved by establishing a technology capable of ensuring the sufficient effect of preventing diameter growth even when the amount of steel used in a belt layer is decreased. The tire includes: two or more crossing belt layers 4 including rubberized layers of steel cords tilting and extending at an angle of 10° to 30° with respect to a tire equatorial plane, the rubberized layers being arranged such that the directions of the cords intersect each other; and a high-angle bell layer 3 including a rubberized layer of steel cords tilting and extending at an angle which is 5° or more greater than the angle of the crossing belt layers. The mass of the steel cords per unit area included in the high-angle belt layer is 85% or less of the mass of the steel cords per unit area included in the crossing belt layers, and compressive rigidity per unit area in a cross section orthogonal to the longitudinal direction of the steel cords of the high-angle belt layer is greater than compressive rigidity per unit area in a cross section orthogonal to the longitudinal direction of the steel cords of the crossing belt layers.

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: a1T−b1>d>a2T+b2 (where a1 is 3.65×10−4 mra/MPa, b1 is 0.42 mm, a2 is −8.00×10−5 mm/MPa, and b2 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).
