Abstract: [Object] To provide a pneumatic tire 22 that allows a low fitting pressure to be achieved without impairing a tightening force. [Solution] The tire 22 includes a pair of beads 30 and a carcass 32 extending on and between both beads 30. Each bead 30 includes a core 48. The core 48 includes: a main body 56 including a cord 60 extending in a circumferential direction; and a stretchable portion 58 formed from a crosslinked rubber. The stretchable portion 58 is located inward of the main body 56 in an axial direction. The stretchable portion 58 has a size with which at least one cross-section of the cord 60 can be included therein in a cross-section of the bead 30. Preferably, in the tire 22, the main body 56 includes a hard unit and a soft unit. The soft unit is located outward of the hard unit in a radial direction. A hard cord of the hard unit stretches more easily than a soft cord of the soft unit.

Abstract: A tread surface (2) of a pneumatic tire is divided by vertical grooves (3a, 3b) on both sides of the tire equator into central land portions (4i), intermediate land portions (4m), and shoulder land portions (4o). The intermediate land portions (4i) have inclined grooves (9). Angle theta of an inclined groove (9) to the circumferential direction of the tire is increased from an inner edge (mi), away from an inner vertical groove (3a) by distance La, to an outer edge (mo) where the inclined groove (9) intersects an outer vertical groove (3b). Angle thetai at the inner end (mi) is set to 0-25º and the angle thetao at the outer end (mo) is set to 60-80º. A circumferential interval (P1) of inclined grooves (9) is made larger than a circumferential interval (P2) of lug grooves (5) in the shoulder land portions (4o).

Abstract: A pneumatic tire including a longitudinal main groove formed concavely on a tread surface thereof in a radial direction thereof by extending the longitudinal main groove linearly in a circumferential direction thereof; and narrow grooves formed concavely on at least an outer side surface of both side surfaces of the longitudinal main groove opposed to each other in a widthwise direction of the pneumatic tire by spacing the narrow grooves at certain intervals in a circumferential direction of the pneumatic tire. Each of the narrow grooves is so configured that a longer side of each of the narrow grooves extends in the radial direction of the pneumatic tire and that a shorter side of each of the narrow grooves extends in the circumferential direction of the pneumatic tire. A sectional configuration of a position having a maximum sectional area in each of the narrow grooves is circular arc-shaped.
