The invention discloses a monitoring method for tire pattern abrasion. The monitoring method comprises the following steps that S1, the power spectrum density of an original acceleration signal is calculated; s2, based on the acceleration signal, the acceleration signal can have an obvious peak value when entering the sensor grounding area every time, and the rotating speed of the tire is calculated according to the peak value; s3, the original acceleration signals are sampled at equal time, the sampling rate is recorded as fs, the time interval of the acceleration signals is 1/fs, tire tread patterns are periodic components of the acceleration signals in the tire rotation process, and in order to effectively strip the periodic components, the original acceleration signals are sampled at equal angles; and S4, measuring the wear condition of the tire according to the energy dispersion degree. According to the invention, separation of pattern components and structural components of tire vibration signals, monit
