PROBLEM TO BE SOLVED: To provide a pneumatic tire 32 that achieves improvement in durability when the internal pressure is decreased due to a blowout while suppressing an increase in mass.SOLUTION: A tire 32 is assembled on an outer surface of a toroidally-shaped core and formed by being pressurized and heated in a cavity formed between a mold and the core. The tire 32 includes: sidewalls 36; beads 40; a carcass 42; load supporting parts 52 each axially located on the inside of the sidewall 36 and radially extending along the carcass 42; and reinforcing parts 54 radially outwardly extending from the beads 40 along the carcass 42. The beads 40 respectively include a spirally-wound bead wire 68. The load supporting parts 52 cover the reinforcing parts 54. The reinforcing parts 54 respectively include a spirally-wound reinforcing wire 82. The reinforcing wire 82 is integrated with the bead wire 68. |
