Abstract: A side-reinforced run-flat tire with improved run-flat durability and riding comfort is easily compression-molded using a conventional bladder. The tire includes a tread (2), shoulder portions (3), side walls (4), and beads (5), each including a bead core (6) and a bead filler (7). A carcass ply (8) having a main part (8a) and a folded part (8b) extending from a crown (9) along the inner sides of the shoulder portions (3) and the side walls (4) to the beads (5), and folded around the outer surfaces of bead cores (6) from the inner sides to the outer sides of the bead cores in the tire width direction so as to run up in the tire radial direction outwardly. Reinforcement rubber layers (11) are widthwise provided on the inner sides of the side walls (4). A bead-reinforcing layer (12) is provided on a side (left in drawing) undergoing larger stress during run-flat driving.
