An intelligent tire monitoring system includes a tire body, a sheet-shaped conductive polymer sensor, a micro control unit, an RF unit, a computer, and an RF circuit. The sheet-shaped conductive polymer sensor is affixed to an inner liner layer at a middle portion of a tire crown. One end of the sheet-shaped conductive polymer sensor is connected to the micro control unit through the RF unit, and the other end of the sheet-shaped conductive polymer sensor is connected to the computer through the RF circuit. The computer includes a power supply module, a communication port, a display screen, an audible alarm, a press-key input module, and a processor. The state of the tire is comprehensively determined by matching or combining a strain amplitude of the tire crown and an operating temperature with a fitting function.
