TIRE WEAR CONDITION PREDICTION SYSTEM, TIRE WEAR CONDITION PREDICTION PROGRAM AND TIRE WEAR CONDITION PREDICTION METHOD

Provided with a sensor unit (SU); a strain signal acquisition unit (201) configured to acquire a strain signal; an index calculation unit (202) configured to calculate an index of deformation rate; a relation value calculation unit (203) configured to calculate in advance a relation value between the index of the deformation rate and a wear degree of the tire; a wear condition estimation unit (204) configured to estimate the wear degree of the tire by comparing the relation value with the index of the deformation rate; and a relation value prediction unit (205) configured to predict a relation value of a tire of another size, and the relation value prediction unit (205) uses data related to at least a thickness of a tire tread portion, which is stored in advance in a data storage unit (206), when predicting the relation value of the tire of another size.
