In order to provide a method for accurately estimating a degree of wear of a tire during travelling regardless of a tire wear shape, there is provided a tire wear estimation method for estimating a degree of wear of a tire, in which the degree of wear is estimated 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 mounted on the tire; 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 and an effective radius, the tire radius being a radius of the tire under a non-loaded state and the effective radius being a radius of the tire during travelling.
