Heavy duty pneumatic radial tires with organic fiber cord bead reinforcing layer
Abstract:
A tire wherein one or more rubberized organic fiber cord layers extending over an end of a carcass turnup portion in a radial direction of the tire are arranged so as to extend from a position near to an outside of the bead core over the end of the turnup portion toward the outside of the tire and spread apart to the turnup portion. A tire wherein one or more rubberized organic fiber cord layers are arranged so as to extend from a position exceeding over an end of a bead portion reinforcing layer made of a steel cord layer toward the outside of the tire extending over the end of the turnup portion in the radial direction of the tire and spread apart to the reinforcing layer. And also, a tire wherein a cord layer portion of one or more rubberized organic fiber cord layers extending over the end of the turnup portion in the radial direction of the tire and outside the turnup portion has a first bent portion bending toward the inside of the tire.
