摘要： [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.

摘要： The present invention has an object of providing a pneumatic tire that exhibits better uniformity by improving the wire wound body for constituting the bead core. The pneumatic tire 1 comprises a bead core 5 comprising a wire wound body 10 in which one bead wire 10a is spirally wound in a continuous around a tire rotational axis CL so that a plurality of layers of the bead wire are formed in a radial direction of the tire. The wire wound body 10 comprises a first part 13 and a second part 14. The first part 13 comprises a plurality of layers of the bead wire 10a each circumferentially extending with a constant radius from the tire rotational axis CL. The second part comprises a plurality of layers of the bead wire 10a each circumferentially extending while changing its radius from the tire rotational axis CL.

摘要： In a pneumatic tire, a bead core has end portions in a tirewidth direction formed as vertical lines along a tireradial direction. A length of the vertical lines is from 20% to 30% of a core height. In two adjacent bead core layers of first, second and third layers, the radial outer layer tireincludes two or more bead cores more than the radially inner layertire, and a misalignment amount between the bead wires each at an end portion on one side in the tirewidth direction is one-half of a bead wire thickness. A side on which the misalignment amount between the first and second layer bead wires is one-half of the thickness of the bead wire is opposite in the tirewidth direction to a side on which the misalignment amount between the second and third layer bead wires is one-half of the thickness of the bead wire.
