A tire changing machine comprising,

• a T-shaped frame including a standard and a cross member and said standard having a pair of telescopically extendable portions,
• ground-engaging casters at opposite ends of said cross member and at the free end of said standard,
• an upstanding tire engaging post at the free end of said standard,
• a tire support cradle on one of said telescopic standard portions adjacent said post, said cradle extending parallel to said cross member and having rollers at opposite ends,
• a hydraulic cylinder pivotally connected to said other telescopic frame portion and positioned to extend at an angle to the horizontal;
• and a bead-engaging tool on the outer free end of said cylinder for engaging the bead of a tire on said cradle support,
• a second upstanding post, said second post being on said other telescopic frame portion adjacent said tire support cradle, and
• adjustment support means on said second post for selectively vertically pivotally adjusting said cylinder in the desired angular position, said adjustment means including said second upstanding post having a pair of spaced apart plate members, said tool extending between said plate members and a bolt means being selectively vertically positioned between said plate members to support said tool to allow the tool to freely pivot upwardly relative to the bolt means as the tool moves along the curvature of the tire.
