摘要： A pneumatic tire comprises a carcass layer, a belt layer disposed on the outer side in the tire radial direction of the carcass layer, and tread rubber disposed on the outer side in the tire radial direction of the belt layer. The belt layer is formed by laminating a pair of cross belts having belt angles with an absolute value from 10° to 45° both inclusive and mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° relative to the tire circumferential direction. The distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10≤Gsh/Gcc. The groove depth (Dsh) and under-groove gauge (UDsh) of the outermost circumferential main groove have a relationship satisfying 0.20≤UDsh/Dsh.

摘要： A radial tire includes a crown reinforcement or belt having a lightened belt structure. The lightened belt structure is constructed of a multilayer composite laminate that includes a first layer of rubber that radially surmounts, in a direction Z, two other layers of rubber. The first layer of rubber includes weakly heat-shrinkable textile circumferential reinforcers, for example, made of nylon or polyester. The two other layers of rubber are reinforced with monofilaments of high tensile steel. The first reinforcers have a diameter between 0.40 mm and 0.70 mm and a density between 70 and 130 threads/dm, and the second and third reinforcers have a diameter between 0.20 mm and 0.50 mm and a density between 120 and 180 threads/dm.

摘要： A pneumatic tire has a belt layer between a carcass and a tread portion. The belt layer has first and second main working belts, and a reinforcement belt. A cord angle of the reinforcement belt is not smaller than 6 degrees and not larger than 9 degrees and width thereof is equal to or wider than 50% of a tire-section width and not wider than either narrower one of the first and second main working belts. In a state where the pneumatic tire is mounted on a predetermined rim and filled with a minute internal pressure with no load applied, an arc passing points on both maximum width positions and a point on a tire equatorial plane of the reinforcement belt, in meridian section, has a radius of curvature of not smaller than 2500 mm. A total thickness TCE and TSH satisfy a relationship of 1.05TSH≦TCE≦1.35TSH.

摘要： [Object] A pneumatic tire that allows reduction of the occurrence of a TGC and, at the same time, allows reduction of rolling resistance, is provided.[Solution] The tire 12 includes a band 26 disposed radially inward of a tread 14, and a belt 24 disposed radially inward of the band 26. The band 26 includes a cord that is helically wound and extends substantially in a circumferential direction. The belt 24 includes an inner layer 24a, and an outer layer 24b that is layered over the inner layer 24a and disposed radially outward of the inner layer 24a. The inner layer 24a and the outer layer 24b each include multiple cords aligned with each other. The cords in the inner layer 24a and the cords in the outer layer 24b are inclined relative to an equator plane. A direction in which the cords in the inner layer 24a are inclined relative to the equator plane is opposite to a direction in which the cords in the outer layer 24b are inclined relative to the equator plane. Absolute values of inclination angles of the cords in the inner layer 24a and the cords in the outer layer 24b relative to the equator plane are greater than or equal to 35°, and not greater than 55°.
