Abstract
A tire mold has a cavity with a flexible bladder disposed in a central portion of the cavity. The tire mold further includes a first ring connected to a first end of the flexible bladder, and a second ring connected to a second end of the flexible bladder. At least one of the first and second rings is configured to move between a first position and a second position. The flexible bladder is stretched to a maximum axial length when the first and second rings are in a first position. When the first and second rings are in the first position the sum of the first axial length and second axial length is greater than a space between the first ring and the second ring.
