Off-the-road tire abrasion sensor and off-the-road tire

The invention relates to an off-the-road tire abrasion sensor and an off-the-road tire, the abrasion sensor comprises an abradable part and a sensor main body, the abradable part comprises a support body and a flexible circuit board, and the flexible circuit board is embedded in the support body and electrically connected with the sensor main body; the flexible circuit board forms a stepped circuit at intervals from the top end to the bottom of the flexible circuit board through a plurality of wires, and is electrically connected with the sensor main body. According to the abrasion sensor suitable for the engineering extra-huge tire, real-time monitoring of the abrasion loss of the extra-huge tire is completed in a more convenient and reliable mode by means of the level principle, and reliable basic data are provided for maintenance, replacement and service life prediction of the extra-huge tire and judgment of the vehicle condition in time. 本发明涉及一种工程机械轮胎磨耗传感器及工程机械轮胎，所述磨耗传感器包括可磨耗部件、传感器主体，所述可磨耗部件包括支撑体和柔性线路板，所述
