    Abstract: The pneumatic tire of the present technology includes: a tread portion; sidewall portions; and bead portions. A pattern of grooves is formed on the tread portion, and a strip-shaped sound-absorbing member is bonded along the tire circumferential direction to a region of the tire inner surface corresponding to the tread portion via an adhesive layer. A first ground contact region is defined between the tire ground contact edge on one side in the tire width direction and the tire equatorial plane, and a second ground contact region is defined between the tire ground contact edge on the other side in the tire width direction and the tire equatorial plane. The sound-absorbing member is offset with respect to the tire width direction so that the centroid of a cross-section of the sound-absorbing member in a plane that includes a tire axis is located within the first ground contact region.

    Abstract: 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.

    Abstract: A pneumatic tire with improved noise performance while preserving the steering stability and rolling resistance includes, on radially outer side of the crown portion of a carcass, an inclined belt consisting of inclined belt layer(s) having cords inclined at an angle of 35° to 90° relative to the tire circumferential direction, a circumferential belt consisting of circumferential belt layer(s) having cords extending along the circumferential direction, and a tread on radially outer side of the circumferential belt. The circumferential belt includes a high rigidity region across the tire equator wherein the circumferential rigidity per unit width is higher at any location thereof than at any location in the remaining regions. The circumferential rigidity per unit width in the remaining regions is constant in the tire width direction or increases toward the high rigidity region.
