Document Type and Number:
WIPO Patent Application WO/2018/203504
Kind Code:
A1
Abstract:
Provided is a bead ring in which the true strain, tensile strength, and yield strength of bead wires constituting the bead ring are set to specific ranges, whereby the processability during molding can be improved while minimizing production cost. Also provided is a method for manufacturing the bead ring. An annular bead ring 1 comprising bead wires 2 that have been subjected to a drawing process, wherein the bead wires 2 have a true strain ε of 2.80 or higher as calculated by formula (1), a tensile strength of 2000 MPa or higher, and a yield strength of 1700 MPa to 1980 MPa.
