A method for manufacturing a pneumatic tire comprising a tread, sidewalls and a first bead and a second bead, which beads are spaced apart, the first bead and the second bead including:
- a drop shaped bead core, the drop shaped bead core having a cross sectional area comprising or consisting of a circular portion and a tapering portion, and
- an apex positioned adjacent and/or against the bead core, the method comprising:
- connecting the apex to the drop shaped bead core, thereby obtaining an assembly comprising the drop shaped bead core and the apex,
- pre-forming a tire comprising said assembly, and
- vulcanizing the pre-formed tire, thereby obtaining the pneumatic tire.
A pneumatic tire comprising
- a tread,
- sidewalls, and
- a first bead and a second bead, which beads are spaced apart,
- wherein
- the first bead has a first mounting surface, and the second bead has a second mounting surface, which mounting surfaces are adapted for mounting the tire on a rim of a wheel,
- wherein each bead comprises an assembly comprising
- a drop shaped bead core, the drop shaped bead core having a cross sectional area comprising or consisting of a circular portion and a tapering portion, and
- an apex positioned adjacent and/or against the bead core.
