Abstract of the Disclosure A tire dismounting method and machine for use in dis- mounting a tire casing from a wheel rim. The machine has a frame adapted to extend diametrically of the rim to span one-side thereof adjacent the rim flange, and to engage diametrically opposite portions of the rim flange to re- strain movement of said machine axially relative to the rim, while the rim and tire assembly are supported freely on the floor or the like. A ram is pivotally supported on the frame adjacent one longitudinal end thereof for orientation of the ram with its axis generally parallel to the rim axis in operation of said ram. The ram has a piston with a presser shoe pivotally carried on its free end for movement in a travel path radially outwardly of and adjacent the rim flanges and generally parallel to the axis of the rim through a working stroke extending axially beyond the remote rim flange. The ram is supported for pivotal motion such that the ram axis can move through a range of about 15° from generally parallel to the rim axis to an acute angle intersecting the rim axis on the machine side of the rim. The machine includes springs between the ram and frame for yieldably biasing the ram toward that end limit of its travel generally parallel to the rim axis. A strap coupled between the springs and ram transmits the spring biasing forces and is removable so that the ram may be pivoted to a storage position against the machine frame. A pair of outriggers may be mounted to the frame for swinging movement from a retracted to an extended position wherein the outriggers are adapted to rest upon the rim flange to reduce the likelihood of tipping of the machine relative to the rim.
