To increase the accuracy of analyzing the shape of grounding of a tire.SOLUTION: A tire grounding shape analyzer 1 includes: a driving device 5 as a road surface driving unit for driving a road surface plate 11, with which an analysis target tire is in contact, so that the plate will be relatively moved to a tire 60; and a camera 15 as a grounding characteristics acquisition unit for acquiring the grounding characteristics of the tire 60 for each measurement angle while the tire 60 is in contact with the main surface of the road surface plate 11, which is driven by the driving device 5 and is moved. At least one of the on-circle average value of the grounding characteristics of the tire 60 in the position on the circle and the on-circle change rate of the grounding characteristics of the tire 60 in the position on the circle is calculated on the basis of the grounding characteristics acquired by the camera 15.SELECTED DRAWING: Figure 1

    【課題】タイヤ接地形状の解析精度を高める。【解決手段】タイヤ接地形状解析装置1は、解析対象であるタイヤが接地する路面となる路面板11を、タイヤ60に対して相対的に移動するように駆動する路面駆動部である駆動装置5と、駆動装置5の駆動によって移動する路面板11の主面にタイヤ60が接地している状態において、タイヤ60の接地特性を測定角度毎に取得する接地特性取得部であるカメラ15とを含み、カメラ15によって取得した接地特性に基づいて、タイヤ60の周上位置の接地特性の周上平均値と、タイヤ60の周上位置の接地特性の周上変動率と、の少なくとも一方を算出する。【選択図】図1
