Title:
PNEUMATIC RADIAL TIRE FOR HEAVY LOADS
Document Type and Number:
WIPO Patent Application WO/2016/185893
Kind Code:
A1
Abstract:
This tire 10 is provided with a carcass 14, and a wire chafer 22 disposed on an outer peripheral side of the carcass 14. A reinforcement rubber layer 24 having a modulus of elasticity lower than that of a coating rubber included in the carcass 14 and/or that of a coating rubber included in the wire chafer 22, is disposed between the carcass 14 and the wire chafer 22. In an area where the reinforcement rubber layer 24 is disposed, the angle θ of rotation of a bead core 12 about the center 12c outward in the width direction of the tire falls within at least a portion of the range of -45° to 90° with reference to a straight line which extends inward in the radial direction of the tire from the center 12c of the bead core 12, which is perpendicular to the width direction of the tire, and which intersects with the wire chafer 22.
