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： A bead core-apex subassembly comprises an annular bead core, a flipper and an apex. The flipper is wrapped about the bead core such that it encloses the bead core. The apex is in contact with the flipper and comprises at least a first segment and a second segment, the first segment having a composition different from the composition of the second segment. A method comprises the steps of providing an annular bead core; wrapping a flipper about the annular bead core; positioning the bead core with the flipper on a rotatable support surface; providing a nozzle in fluid communication with a pumping or extrusion device; rotating the support surface about an axis; and discharging a rubber compound through the nozzle onto the rotating support surface and forming an apex from the discharged rubber compound, the apex being attached to the flipper.
