摘要： Provided is a pneumatic tire that includes a belt reinforcing layer formed of an organic fiber cord and allows providing improved durability of the tire and weight reduction and a reduction in rolling resistance of the tire in a compatible manner. A belt layer (7) disposed on an outer circumferential side of a carcass layer in a tread portion (1) is made of a monofilament wire having a wire diameter of 0.30 mm or more and 0.45 mm or less. A belt reinforcing layer (8) disposed on an outer circumferential side of the belt layer (7) is made of a belt reinforcing cord made of a polyethylene terephthalate fiber and having an intermediate elongation under 2.0 cN/dtex load of from 2.0% to 4.0%. Circumferential portions of a strip (S) in which belt reinforcing cords (8c) are arranged are disposed at intervals in a tire width direction.

摘要： In a tire (2) for a two-wheeled automotive vehicle, a carcass ply (24) is extended on and between one bead (8) and the other bead (8) along inner sides of a tread (4) and sidewalls (6), and includes a main portion (24a) and turn-up portions (24b), which are formed by the carcass ply (24) being turned up around the beads (8) from an inner side toward an outer side in an axial direction. An outer end Pp of each turn-up portion (24b) is positioned outward of a tread end Pe in a radial direction. A band (14) is positioned between a belt (12) and the tread (4), such that the band (14) covers the belt (12). An outer end PI of an inner layer (28) layered over a carcass (10) and the outer end Pp of the turn-up portion (24b) are positioned facing each other.

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 belt 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： A pneumatic tire excellent in high speed stability and turning ability is provided. In a band of a tire, a center portion located in an axial center has a helically wound structure in which a first band body including a first cord is wound. A shoulder portion located on an axial outside of the center portion has a meshed structure formed by a second band body including a second cord. The shoulder portion includes a plurality of first portions, a plurality of second portions and a plurality of third portions. Each first portion is inclined and extends from an axially inner end of the shoulder portion to an axially outer end of the shoulder portion. Each second portion is inclined in an opposite direction from the first portion and extends from the axially inner end of the shoulder portion to the axially outer end of the shoulder portion.
