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.

    本发明的一方式的轮胎劣化推断方法使用配置于轮胎的内侧面的轮胎劣化推断装置,具备:变形速度测量步骤(S11),测量轮胎正在旋转时的轮胎的变形速度即轮胎变形速度,获得所述轮胎变形速度的时间序列变化;计算步骤(S12),根据所述轮胎变形速度的时间序列变化计算所述轮胎变形速度的峰值;以及推断步骤(S13),使用所述轮胎变形速度的时间序列变化中的所述轮胎的踏入时以前或者蹬出时以后的所述轮胎变形速度的所述峰值即第一峰值,推断所述轮胎的劣化度,因此,能够推断轮胎的劣化程度。
