<p>A tire risk judging device of a wheel assembly for a vehicle has a pressure sensor S1 detecting air pressure of a tire air chamber Rb, an air pressure-generating device A which can supply pressurized air to the tire air chamber Rb, an electronic control unit ECU, and an instrument panel display unit ID. The electronic control unit ECU has supply airflow rate computation means for computing a supply airflow rate supplied from the air pressure-generating device A to the tire air chamber Rb between the present location and a specified location, leakage airflow rate computation means for computing a leakage airflow rate leaked from the tire air chamber Rb between the present location and the specified location, tire air pressure computation means for computing air pressure in the specified location of the tire air chamber Rb based on air pressure in the present location of the tire air chamber Rb, the supply airflow rate, and the leakage airflow rate, and specified location tire risk judgment means for judging tire risk in the specified location based on the air pressure in the specified location of the tire air chamber Rb.</p> |
