Abstract: A tire derimmer and method for derimming, the tire derimmer including a base edge partially bounding the opening. A jaw is movable between a raised position and a lowered position. The jaw is disposable in the lowered position to clamp a tire against the base, adjacent the opening and opposite the working edge. A ram is connected to the jaw. The ram is extendible against a wheel mounted to a tire clamped by the jaw, to pivot the wheel about the working edge and separate the wheel from the tire.
