摘要： There is provided a system and method for quantitative analysis of a cause of tire trouble capable of quantitatively analyzing whether the tire trouble is caused by the tire itself or in a matter of harshness of a tire using condition in light of not only a force acting on a tire mounted on a running vehicle but also harshness of a tire using condition such as a traveling speed of the vehicle, level difference of a road surface, a curve and gradient information. The method for quantitative analysis of a cause of tire trouble according to the present invention is characterized by comprising the steps of receiving positional data of a running vehicle from the GPS, simultaneously measuring triaxial accelerations which are accelerations acting on the running vehicle in back-and-forward, right-and-left and up-and-down directions while time synchronizing with the received data, quantitatively analyzing harshness of a tire using condition from the received positional data and the triaxial acceleration data, and displaying an analysis result.
