To provide a test method of a tire T capable of correctly grasping a contact state of a tire T to a road face 12.SOLUTION: A test method is a test method of a tire T for observing slide of the tire T rolling on a test road 4 comprising at least partially a transparent part 14, to the test road 4. The test method comprises an imaging step of imaging a contact surface of the tire T to a top surface 32 of the transparent part 14 from a lower surface 28 side of the transparent part 14. The top surface 32 of the transparent part 14 comprises many top surfaces 38. Between one top surface 38 and other top surface 38 adjacent to the one top surface 38, a recess 42 is provided. The plurality of top surfaces 38 are included in a same plane and the top surfaces 38 are parallel to the lower surface 28 of the transparent part 14.SELECTED DRAWING: Figure 3

    【課題】タイヤTの、路面12との接触状態を、より正確に把握できる、タイヤTの試験方法の提供。【解決手段】この試験方法は、少なくとも一部に透明部分14を有する試験路4を転動しているタイヤTの、当該試験路4に対する滑りを観測する、タイヤTの試験方法である。この試験方法は、前記タイヤTの、前記透明部分14の上面32との接触面を、当該透明部分14の下面28側から撮影する、撮影工程を含む。前記透明部分14の上面32は、多数の頂面38を含む。一の頂面38と、当該一の頂面38の隣に位置する他の頂面38との間は、凹み42である。前記複数の頂面38は同一平面に含まれ、それぞれの頂面38は前記透明部分14の下面28と平行である。【選択図】図3
