The tire run-flat ring removal and installation machine (10) includes mechanisms for removing and replacing the run-flat ring from a tire T. A first mechanism has a powered reel (22) and straps (26a) through (26d) extending through a tower 98 in the center of the table (12) of the machine (10). Straps (26a) through (26d) are secured about a run-flat ring for compressing the ring. A second mechanism has a powered reel (28) and strap (32) for extracting the run-flat ring from the tire casing while the casing is secured to an extension (68, 72) of the machine (10). The tire T is then placed over the compressed ring and installed thereon. A davit and winch (44), (40) are provided for lifting the run-flat ring and tire T to and from the table (12) and tower 98, and for removing the completed tire and ring assembly from the table (12). |
