To provide a taking out method and tool for a foamed support ring for a touring car.
The method for taking out the foamed support ring (B) from an internal space of a tire (P) has a stage for forming a space (E) between an apex part of the foamed support ring and a bead of the tire; a stage capable of introducing a first roller (1) into the space (E) by introducing a means (F) capable of maintaining the accessable space (E) into the space (E); and a stage for introducing second and third rollers (2, 3) into an internal space formed by an inner diameter of the foamed support ring. The method further has a stage for moving the first roller (1) relative to the second and third roller (2, 3) after a retaining means (F) is taken out and pressing the foamed support ring to a space between the second and third rollers (2, 3) to make it to a U shape; and a stage for releasing the foamed support ring by operating the rollers (1, 2, 3).
