In order to provide a method for efficiently estimating a degree of wear of a tire, a tire wear estimation method is provided in which a normalized deformation speed index is set as a wear measure, the normalized deformation speed index being obtained by normalizing, by a rotation time of the tire, an index of a deformation speed near an edge of a tire contact patch, the index being calculated from magnitudes of peaks appearing in a radial acceleration waveform obtained by differentiating tire radial acceleration detected by an acceleration sensor,; and the degree of wear of the tire is estimated using the wear measure and a ground contact time ratio which is a ratio of a ground contact time with respect to the rotation time, in which the degree of wear of the tire is estimated using the wear measure, the ground contact time ratio, a worn tire approximate formula and an approximate formula when a tire is new, which have been obtained in advance and each represents a relationship between the wear measure and the ground contact time ratio obtained by running a plurality of tires having tire sizes different from each other.
