PROBLEM TO BE SOLVED: To provide a method of quantitative analysis for the cause of failure of a tire capable of quantitatively analyzing whether the failure of the tire is caused by the quality of the tire itself or the severeness of its service condition while considering not only the force imparted to the tire mounted on the vehicle but also severeness of service condition such as the running speed of the vehicle, the surface unevenness of the running road, and information of curve and inclination. SOLUTION: The quantitative analysis method is characterized in that the 3-axial acceleration are simultaneously measured by receiving the positional data of the running vehicle from GPS, and synchronizing the reception and the 3-axial acceleration of back and forth, left and right, and up and down directions. From the received vehicle positional data and the measured 3-axis acceleration data, the severeness of service condition is quantitatively analyzed and the analyzed results are displayed.
