A tire air pressure warning device includes a tire air pressure sensor and at least one controller that warns a driver that a tire air pressure detected by the tire air pressure sensor has dropped to or below a first prescribed pressure. The at least one controller further notifies the driver is reduction in the tire air pressure upon determining that the tire air pressure has dropped to or below a second prescribed pressure, which is above the first prescribed pressure. The at least one controller further determines whether the tire air pressure has dropped to or below the second prescribed pressure based on when the tire air pressure is at or below the second prescribed pressure in an ignition switch on state, and whether the tire air pressure has dropped to or below the second prescribed pressure when the ignition switch is turned off.
