  "textContent": "A tire alarm device gives a warning against the runflat operation limit of a pneumatic tire (1) during runflat operation, the tire having a reinforcement layer (13) disposed in each sidewall (12) thereof for enabling the runflat operation. The device includes a tire temperature sensor (44) used to warn of the runflat operation limit, and the tire temperature sensor is disposed on the inner surface (12a) of one of the sidewalls (12) facing the reinforcement layer (13) therein. Embodiments of the device also include a tire inner pressure sensor (45), for detecting pressure in the cavity of the tire, and a speed obtaining means (50) for obtaining the running speed of the vehicle on which the pneumatic tire is mounted, wherein processing means (51) determines whether or not the tire has reached its runflat operation limit based on signals from the temperature sensor (44), the inner pressure sensor (45) and the speed obtaining means (50).",
