PROBLEM TO BE SOLVED: To provide a measuring method and a measuring device of grounding characteristic of a tire capable of measuring the grounding characteristic of the tire at various camber angles and slip angles with high efficiency, high precision and high reproducibility, and acquiring also the grounding characteristic of the tire at a high-speed traveling time.SOLUTION: In this measuring method of the grounding characteristic of the tire, the tire to which camber angles and slip angles are given is allowed to abut on a rotating drum into which a measuring means is buried, and both members are rotated, and while the tire is being displaced in the rotation axial direction of the rotating drum, the ground contact pressure, shearing stress in the width direction, and shearing stress in the circumferential direction of the tire are measured simultaneously. |
