A method for estimating a degree of wear of a tire by using: an index of deformation velocity at a tire contact edge or in the vicinity of the tire contact edge, the index of deformation velocity having been calculated from magnitude of one of or both of positive and negative peaks appearing in a radial acceleration waveform obtained by differentiating a time-series waveform of tire radial acceleration detected by an acceleration sensor; a contact time ratio of contact time to tire rotation time, the contact time being a time interval between the positive peak and the negative peak, the tire rotation time being a time interval between either of positive peaks or negative peaks; and a deformation amount which is a difference between a tire radius of the tire under a non-loaded state and an effective radius of the tire during travelling.
