A unitary structure tire lever has an opening for the user to insert fingers and grab the lever when installing and removing a tire from a rim. The lever has a curved smooth installation hook at one end with a ridge to engage a lip of a tire rim during tire installation. The lever also has a curved smooth removal hook at the other end with a notch that enables the lever to pivot about the lip of the tire rim during tire removal. The removal hook also has a curved seat portion that engages with a bead of the tire during tire removal.

A tire-lever device for tire-changing machines includes a substantially vertical support arm associated with a tire-changing machine and having upper and lower ends; a pair of substantially vertical and parallel plates integrally extending from the opposite lower end; a connecting rod system, hinged between the pair of plates and including first and second connecting rods; a tire-lever tool with an elongate body defining an upwardly-facing first end and a second end opposite thereto, formed as a hook portion and hinged to the first and second connecting rods and forming an articulated quadrilateral with the latter and said plates; an actuator rotatably actuating the connecting rod system and mounted onto the support arm; a connector element connecting the actuator to the connecting rod system and defining an end hinged to the actuator and an opposite end directly hinged to the first end of the elongate body of the tire-lever tool.

In some examples, a tool for fitting and removing a tyre on a wheel rim comprises an elongate body forming a handle for the tool, wherein the elongate body is generally planar in form, having a plane and a longitudinal axis, a tyre-engagement portion arranged to, in use, engage with an outer side wall of the tyre to thereby facilitate fitting of the tyre, the tyre-engagement portion having a plane which is co-planar with the plane of the elongate body, and a hook portion, orthogonal to the longitudinal axis of the elongate body, arranged to, in use, engage with an inner side wall of the tyre to thereby facilitate removal of the tyre.

A tool for installing a tyre onto a wheel rim includes: a shoe, and a body, connected to the shoe, providing a handle portion. The shoe includes: a first surface for contacting an inner portion of the wheel rim side wall; a second surface, with the surfaces forming, a channel for receiving the wheel rim radially outer edge; a toe projecting beyond the leading edge of the second surface in the circumferential direction of the wheel rim and continuing the first surface in the circumferential direction; and a shoulder. When installing a tyre, at the cross-over point where the bead of a partially installed tyre crosses from outside the wheel rim to inside the wheel rim, the surfaces are contactable with the inner portion of the side wall and radially outer edge of the wheel rim, respectively, with the toe portion projecting underneath the bead of the tyre.

Embodiments of the present disclosure provide a tire mounting component and device and a tire mounting/dismounting device. The tire mounting component comprises a main body and a pressing member capable of pressing down the tire, and the pressing member is arranged on the main body. A protective member is arranged on the main body, the protective member is at least partially located above the pressing member, and a portion of the protective member that is located above the pressing member can block at least a portion of a top surface of the pressing member. During mounting of the tire, the protective member can prevent an inner edge of the tire from coming into contact with the at least a portion of the top surface of the pressing member to prevent the inner edge of the tire from being stuck on the pressing member.
