Abstract: An upright generally rectangular frame includes a pair of base members transversely journalling a spaced-apart pair of power driven rollers for vertically supporting, in rolling relation, a tire rolled into the frame through one of its ends. A pair of brake chambers, supported by the base members, are connected with moveable arms having tire bead engaging rollers thereon for spreading the opposing tire beads apart.

Abstract: A vehicle bumper step formed by an upwardly open frame having clamp members secured to its upper surface for mounting the frame on a vehicle bumper by gripping a bumper flange. Longitudinally adjustable arms, connected with the frame, project toward a vertical surface of the bumper for stabilizing the position of the frame relative to the bumper. A step having a tread portion is movable from a first position nested by the frame to a second position projecting horizontally beyond the bumper in a direction outwardly from the vehicle and includes a hook portion engaging the frame normally preventing separation of the step relative to the frame.

Abstract: An upright rigid open frame surrounds a wheel rim mounted tire when disposed therein. One side of the frame supports a pressure cylinder projecting laterally of the frame with its longitudinal axis normal to the plane of the opposite side of the frame. That side of the frame opposite the pressure cylinder forms a backstop for the rim and tire. An endless cylindrical ring, coaxially supported by the pressure cylinder piston rod, is moved toward and away from the tire side wall adjacent the periphery of the rim tire bead flange. A rim and tire supporting platform, hingedly connected with the frame base portion, is vertically adjustable for coaxially aligning of the rim with the pressure cylinder.
