摘要： A pneumatic tire for passenger cars has a tread and left and right beads, the beads each having a bead core embedded therein with a bead filler disposed on the outer circumferential side of the bead core, at least one carcass ply being arranged to extend between the beads, the carcass ply having reinforcing cords which extend in a width direction of the tire and are aligned at a predetermined interval along a circumferential direction of the tire, and two belt plies being disposed on the outer circumferential side of the carcass ply in the tread. An average of residual strain of the reinforcing cords of an innermost carcass ply is set to −10% to 5% in each side region located between an outer circumferential end of the bead filler and an end of an overlapping portion of the two belt plies.

摘要： Provided are a pneumatic radial tire production method which enables to improve uniformity of a tire and also to prevent a separation failure caused by trapped air, and a belt tread assembly transfer apparatus used for the method. A pneumatic radial tire production method includes the steps of forming a primary green tire including a carcass layer; forming a cylindrical belt tread assembly including belt layers; transferring the belt tread assembly to the outer peripheral side of the primary green tire by use of a transfer apparatus; and pressure-bonding the belt tread assembly to the primary green tire inflated in a toroidal shape. In the method, the primary green tire and the belt tread assembly are pressure-bonded to each other in a state where the transfer apparatus allows a center portion of the belt tread assembly to swell while holding both sides of the belt tread assembly.
