A tired wheel comprising at least one base structure, at least one support arm connected to said at least one base structure so as to be angularly displaceable with respect thereto, actuation means for actuating the support arm designed to angularly displace the arm with respect to the at least one base structure, and a demounting tool connected to the support arm so as to be angularly displaceable with respect thereto.

Machine for unseating a tire bead from a wheel, comprising a stand designed to rest on the ground, a bearing plate for the wheel, and a bead unseating tool which is connected to a tool bearing structure mobilely mounted to the stand. The machine comprises a pneumatic actuator for setting the tool bearing structure in motion in order to operate the tool, and a shock absorber connecting the tool bearing structure to the stand in order to damp the movement of the tool bearing structure, particularly at the moment at which the tire bead unseats from the rim of the wheel.

A tire removing device, which is disposed on a wheel rim of a large vehicle for removing a tire, includes a seat provided with a first end and a second end, the first end movably clamping a wheel disk of the wheel rim; a power cylinder disposed on the second end of the seat and provided with a cylinder body and a moving shaft movable against the cylinder body; and a tire removable plate connected to an end of the moving shaft. When the power cylinder is put in operation, the tire removable plate pushes the inner edge of the tire, so as to remove the tire from the wheel rim.

A system for disassembling a tire-wheel assembly includes a dismount stand, a robot, a first assembly, and a second assembly. The robot is disposed adjacent to the dismount stand. The first assembly is configured to detachably connect to the robot and engage the tire-wheel assembly. The first assembly and the robot are configured to retrieve the tire-wheel assembly from an initial location and position the tire-wheel assembly on the dismount stand. The second assembly is detachably coupled to the robot and is configured to disengage a tire of the tire-wheel assembly from a wheel of the tire-wheel assembly.
