A tire degradation estimating method according to an embodiment of the present invention utilizes a tire degradation estimating device configured on the inner side surface of a tire. The method includes: a deformation speed measuring step (S11) of measuring a tire deformation speed, which is the deformation speed of the tire when the tire is rotating, and obtaining a time-series variation of the tire deformation speed; a calculating step (S12) of calculating a peak value of the tire deformation speed from the time-series variation of the tire deformation speed; and an estimating step (S13) of estimating the degree of degradation of the tire by using a first peak value, which is the peak value of the tire deformation speed before lead-in of the tire or after trail-out of the tire, in the time-series variation of the tire deformation speed. Accordingly, the degree of degradation of a tire can be estimated.
