The invention relates to a tire wear degree monitoring method and system, and the method comprises the following steps: performing a monitoring model construction process: collecting triaxial acceleration signals and tire pressure signals of a tire in a tire operation process when the tire is at different wear degree calibration values, and carrying out the analysis and extraction of characteristic parameters, constructing a wear prediction model by taking the wear degree calibration value as a target and the characteristic parameters as independent variables; and performing an operation monitoring process: acquiring a three-axis acceleration signal and a tire pressure signal in a tire operation process in real time, extracting corresponding characteristic parameters, and obtaining a real-time tire wear degree value through the wear prediction model. Compared with the prior art, the wear state of the vehicle tire is monitored in real time, so that the driving safety is improved, and the method and system have the advantages of high precision, low cost and high timeliness.
