To provide a tire degradation diagnosis device with which it is possible to diagnose the degradation state of a tire irrespective of the use state of the tire.SOLUTION: The tire degradation diagnosis device comprises: first acquisition means 11 for acquiring a degradation index value that indicates the level of degradation of a tire 20 attached to a vehicle 100; second acquisition means 12 for acquiring the travel distance of the vehicle 100 from the start of use of the tire 20; storage means 13 in which correlation information that indicates relationship between the degradation index value and the travel distance is stored in advance; correction means 14 for generating first corrected correlation information in which the correlation information is corrected using the degradation index value and travel distance acquired at a first point of time, and second corrected correlation information in which the correlation information is corrected using the degradation index value and travel distance acquired at a second point of time later than the first point of time; and determination means 15 for comparing the first corrected correlation information with the second corrected correlation information and thereby determining the degradation pace of the tire 20.SELECTED DRAWING: Figure 1

    【課題】タイヤの使用状況によらずタイヤの劣化状態を診断することができるタイヤ劣化診断装置を提供する。【解決手段】車両100に取り付けられたタイヤ20の劣化の程度を表す劣化指標値を取得する第1取得手段11と、タイヤ20の使用開始からの車両100の走行距離を取得する第2取得手段12と、劣化指標値と走行距離との関係を示す相関情報を予め記憶した記憶手段13と、第1時点に取得された劣化指標値及び走行距離を用いて相関情報を補正した第1補正相関情報と、第1時点よりも後の第2時点に取得された劣化指標値及び走行距離を用いて相関情報を補正した第2補正相関情報とを生成する補正手段14と、第1補正相関情報と第2補正相関情報とを比較することでタイヤ20の劣化ペースを判定する判定手段15とを備える。【選択図】図1
