To provide a system and a program for estimating the state of a tire which can estimate the depth of a crack in a tire which can be seen from the outer surface of the tire on the basis of the shape of the crack.SOLUTION: A tire state estimation system 10 includes: a crack shape acquisition unit 240 for acquiring the shape of a crack in the outer surface of a tire; and a crack depth estimation unit 250 for estimating the depth of the crack on the basis of crack information DB 230 holding the correspondence relation between one of the opening degree and the displacement width of the crack based on the shape of the crack and the depth of the crack, the shape of the crack, and the correspondence relation.SELECTED DRAWING: Figure 3

    【課題】タイヤの外側表面から認識可能な亀裂の形状に基づいて、当該亀裂の深さを推定し得るタイヤ状態推定システム及びタイヤ状態推定プログラムを提供する。【解決手段】タイヤ状態推定システム10は、タイヤの外側表面における亀裂の形状を取得する亀裂形状取得部240と、亀裂の形状に基づく亀裂の開き具合またはずれ幅の少なくとも何れかと、亀裂の深さとが対応付けられた対応関係を保持する亀裂情報DB230と、取得された亀裂の形状と、当該対応関係とに基づいて、当該亀裂の深さを推定する亀裂深さ推定部250を備える。【選択図】図3
