|1. (WO2018180974) TIRE TESTING METHOD AND TIRE TESTING DEVICE|
|Applicants:||KABUSHIKI KAISHA KOBE SEIKO SHO (KOBE STEEL, LTD.)
|Title:||TIRE TESTING METHOD AND TIRE TESTING DEVICE|
This tire testing method comprises: a step for applying a lubrication solution to a bead part of a tire; a step for detecting the phase of a reference point of the tire; a step for detecting the phase of a rotation origin of a spindle at common coordinates shared with coordinates at which the phase of the reference point is indicated; a step for performing a tire test to detect a singular point present on the tire while rotating the tire by the spindle, and detecting a phase from the rotation origin to the singular point; a step for calculating a phase from the reference point to the singular point on the basis of the phase of the reference point, the phase of the rotation origin, and the phase from the rotation origin to the singular point; a step for storing information about the reference point at the common coordinates and information about the rotation origin at the common coordinates; and a step for marking the tire at the position along the circumferential direction at which the singular point is present.
