Abstract
An apparatus and method derives a deformation amount of a contact-portion of the tire based on the tire information, the contact-portion being in contact with the ground, and calculates an evaluation value based on the derived deformation amount, and comparing the calculated evaluation value with a reference value to determine whether or not the internal mechanical failure has occurred in the tire.

An apparatus for detecting an internal mechanical failure of a tire that is attached to a wheel of a vehicle while the vehicle is traveling, including:
- an information acquiring part for acquiring tire information on the tire during rotating while the vehicle is traveling;
- a deriving part for deriving a deformation amount of a contact-portion of the tire based on the tire information, the contact-portion being in contact with the ground;
- a calculating part for calculating an evaluation value based on the derived deformation amount;
- and
- a determining part for comparing the calculated evaluation value with a reference value to determine whether or not the internal mechanical failure has occurred in the tire.
