Abstract
A system for notifying a driver in a vehicle of a level of danger of an occurrence of tire failure according to the present invention has a danger level assessment device which calculates a danger level assessment value indicating an index showing a probability of the occurrence of the failure from a measured tire inflation pressure and a measured tire running speed, using a characterized danger level assessing function to assess the danger level according to the calculated value. The characterized assessing function is a function of a tire running speed and of a tire inflation pressure, in which a value of the function monotonously increases as the tire running speed increase and as the tire inflation pressure decreases. The danger level assessment value is obtained by adding a cumulative value determined according to usage history of the tire to a value calculated from the danger level assessing function with the measured tire running speed and the measured tire inflation pressure.
