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.
A bead core-apex subassembly, the subassembly comprising an annular bead core, a flipper and an apex, wherein the flipper is wrapped about the bead core such that it encloses the bead core, and wherein 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 pneumatic tire comprising a bead core-apex subassembly, the subassembly comprising an annular bead core, a flipper and an apex, wherein the flipper is wrapped about the bead core such that it encloses the bead core, and wherein 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.
