To provide a tire testing device.SOLUTION: A drum type tire testing device includes: a drum having a sensor for measuring grounding force of a tire and a transmission section on an outer peripheral surface; a photographing device for photographing a grounding surface of the tire through the transmission section from the inside of the drum; a grounding force measurement processing section for measuring the grounding force of the tire grounded on the sensor; a grounding surface photographing processing section for photographing the grounding surface by the photographing device when the tire grounds on the transmission section; and a slip amount calculation processing section for calculating a slip amount by displacement calculated using image information of two or more corresponding grounding surfaces corresponding to the grounding surface of the tire measured by the grounding force measurement processing section and different in grounding force.SELECTED DRAWING: Figure 1

    【課題】タイヤ試験装置を提供することを目的とする。【解決手段】ドラム式のタイヤ試験装置であって,タイヤ試験装置は,外周面にタイヤの接地力を計測するセンサと透過部とを有するドラムと,ドラムの内側から透過部を介してタイヤの接地面を撮影する撮影装置と,センサに接地したタイヤの接地力を計測する接地力計測処理部と,タイヤが透過部に接地したときの接地面を撮影装置で撮影する接地面撮影処理部と,接地力計測処理部で計測したタイヤの接地面に対応しており,かつ,接地力が相違する,対応する2以上の接地面の画像情報を用いて算出した変位により滑り量を算出する滑り量算出処理部と,を備えるタイヤ試験装置である。【選択図】 図1
