The invention provides an optimal tire pressure reminding method of a blade electric vehicle. The method comprises the following steps of (1) signal collection, wherein a whole-vehicle controller collects steering angle signals and speeds of wheels; (2) data filtering, wherein the whole-vehicle controller judges whether a current driving condition of the vehicle is a condition suitable for manual intervention or not according to the collected steering angle signals, and under the manual intervention station, the wheel speeds are stored; (3), rolling radius comparing, through algorithm setting, the whole-vehicle controller judges whether the tire pressures of the wheels are within the preset tire pressure range or not on the basis of the stored wheel speed data, and the tire pressure range is determined according to rolling resistance; (4), manual intervention reminding, wherein when the tire pressures are out of the set tire pressure range, a warning unit reminds a driver to adjust the tire pressures in a manual intervention manner. The optimal tire pressure reminding method avoids the phenomenon that due to station and environment changes, when the tire pressures are changed, the economy of the whole vehicle is reduced, and hidden safety troubles are caused.
