Pneumatic tire and method of manufacturing the same

A method of manufacturing a pneumatic tire comprising the steps of:

• laminating an inner liner onto a building drum;
• placing a pair of beads including bead cores and bead fillers on the inner liner at equal distances with respect to the center of a tire width;
• winding both end portions of the inner liner around the beads to the outside in the tire width direction, and pressure-bonding the bead fillers to the inner liner;
• laminating a carcass ply to the bead fillers pressure-bonded to the inner liner;
• laminating side wall rubbers to the carcass ply;
• forming a green case by pressure-bonding the carcass ply and the side wall rubbers to wound portions of the inner liner, and by folding back both end portions of the carcass ply toward an inner peripheral side of the beads;
• and
• enlarging the green case, laminating a tread ring formed of a belt and a tread rubber to the green case and, thereafter, winding both end portions of the carcass ply around the beads to the inside in the tire width direction.
