A rim for a pneumatic tire carcass has a pair of rim portions which are securable together to form such rim. One rim portion is integral with a wheel hub and includes a plurality of pockets or guide openings formed therein. The other rim portion includes guide members which correspond to these pockets and which are positionable therein to position the rim portions relative to each other. Apparatus for separating the rim portions with the tire carcass mounted on them is disclosed, as is apparatus for pulling the tire carcass off a rim portion after the other rim portion has been separated therefrom. In another embodiment, a pair of rim portions are assembled by positioning posts fixed on one rim portion into angled slots defined by the other rim portion, and rotating one rim portion relative to the other, the posts being drawn into the slots during such rotation to draw the rim portions together. In yet another embodiment, the tire carcass is supplied with an inner peripheral stiffener, which is seatable in a groove formed by a pair of fixed-together rimmed portions to center the tire carcass thereon. Also, another embodiment includes an annular plate and rim portions mounted in spaced relationship on either side thereof.
