A foam support ring is extracted from a tire by pushing radially inwardly against a portion of the tire's tread until the support ring is deformed to such an extent that a space is formed between tire beads and the outer periphery of a portion of the support ring. A tool is inserted into that space to keep the space open when the radial force is released. That enables a first roller to be inserted into the space and displaced relative to two other rollers that have been inserted in an internal area bordered by the beads, in order to further deform the support ring to a U-shape that can be easily extracted from the tire. |
