TIRE PROVIDED WITH TREAD DEFORMATION MEASURING MEANS AND DEFORMATION DETECTION METHOD FOR TIRE TREAD

摘要

PROBLEM TO BE SOLVED: To detect the deformation of a tire tread when the behavior of a vehicle body is abnormal and transmit an abnormality signal to a control system of the vehicle body early. SOLUTION: A tire 11 is constituted by burying a positive electrode 15 and a negative electrode 15 inside the tire tread 11a at an interval in the direction of tread width. The positive electrode 15 and the negative electrode 15 are connected with a voltage load unit 12 and an electric resistance measuring unit 13 which are loaded on the vehicle body by radio, and electric resistance of tire tread rubber between the electrodes in accordance with a voltage load by the voltage load unit 12 is measured by the electric resistance measuring unit 13. The electric resistance measuring unit 13 measures electric resistance at a predetermined interval and transmits an abnormality signal to the control system of the vehicle body when a difference between current measured value and a measured value in the past exceeds a fixed value.
