A tire holding apparatus which holds a tire using an annular rim that is detachably mounted, includes: a body section having a support surface which supports the rim; an inflation gas supply portion which has an inflation flow passage that passes from an inner portion of the body section to a center portion of the rim and supplies inflation gas into a tire supported by the rim; and a clamping portion which is mounted on the body section and clamps the rim to the support surface of the body section by using pressure of the inflation gas that flows through the inflation flow passage as a drive force.
