The invention provides a tire pressure management method and device and a computer storage medium, and the tire pressure management method comprises the following steps: respectively carrying out linear regression fitting on tire data of multiple groups of samples, and calculating a sample residual error of each linear regression fitting to obtain a fitting residual error threshold value and a tire pressure change rate threshold value and/or a tire temperature change rate threshold value; performing linear regression fitting on real-time sampling tire data of the to-be-measured tire, and calculating a real-time residual error of the linear regression fitting to obtain a tire pressure change rate and/or a tire temperature change rate of the to-be-measured tire; when the tire pressure change rate is not greater than the tire pressure change rate threshold value and/or the tire temperature change rate is not greater than the tire temperature change rate threshold value, comparing the real-time residual error with the residual error threshold value; and when the real-time residual error is not greater than the fitting residual error threshold value, generating a tire pressure warning signal. The slow air leakage of the running vehicle can be monitored in real time and identified and alarmed in time through the linear regression model.
