Abstract

See full text

A tire testing method includes: applying a lubrication solution to a bead part of a tire; detecting a phase of a reference point of the tire; detecting a phase of a rotation origin of a spindle at common coordinates shared with coordinates at which the phase of the reference point is indicated; detecting a singular point present on the tire by conducting a tire test while rotating the tire on the spindle, and detecting a phase from the rotation origin to the singular point; calculating a phase from the reference point to the singular point based on the phase of the reference point, the phase of the rotation origin, and the phase from the rotation origin to the singular point; storing information about the reference point and information about the rotation origin at the common coordinates; and marking the tire at a position where the singular point is present.
