A hand-tool is provided for installing and removing a tire, comprising a substantially elongated body member having a longitudinal axis, the body member further comprising a handle portion (102); a first engagement portion (108), arranged at a first end of said handle portion, adapted to operably engage with a first flange of opposed first and second rim flanges of a wheel, so as to form a fulcrum on the contact point with the first flange; a second engagement portion (112), spaced apart at a predetermined distance in a direction away from said first engagement portion along said longitudinal axis, adapted to abuttingly engage with a rim-overlapping bead portion of a tire.

A dampening system for a tire-bead loosener may have a lever in communication with an operation valve, the operation valve configured to channel a supply flow having a supply flow pressure through a first line into a first port of a cylinder and an exhaust flow having an exhaust flow pressure through a second line out of a second port of the cylinder. A pressure line connecting the first line to the second line may include a preset pressure relief valve, a pressure regulator, and a check valve. A bypass flow of the supply flow may move through the pressure line and achieve a damped pressure, thereby channeling through the second line and into the second port of the cylinder. The supply flow pressure in the first port of the cylinder may be cushioned against the exhaust flow pressure and the damped pressure in the second port of the cylinder.

A wheel assembly includes a collapsible wheel and an airless flexible tire mounted on the wheel. The wheel includes a central portion and a plurality of circumferentially spaced mounting elements attached to the central portion. Each of the mounting elements is movable between a retracted position and an extended position, and may be pivotally attached to the central portion of the wheel and configured to pivot between the retracted position and the extended position. The tire may be positioned on the wheel when one or more of the mounting elements is in the retracted position, and the one or more mounting elements are moved to the extended position wherein the mounting elements engage and support the tire.

The present invention relates to a lubricating agent for mounting or releasing a tire bead, comprising alkaline electrolyzed water and a lubricant component. The lubricant component comprises a lubricant base oil, which is made up of a mineral oil and/or a synthetic oil, and a surfactant. The present invention relates to a method for producing a lubricating agent for mounting or releasing a tire bead, the method comprising: mixing an alkaline electrolyzed water with a lubricant component. A tire and wheel assembly method, comprising: applying the above lubricating agent onto a contact surface of the wheel with a tire bead, and thereafter assembling the tire onto the wheel having had the lubricating agent applied thereon. A method for dismantling a tire and wheel integrated together, comprising: causing the above lubricating agent to seep onto a part of a contact surface of a wheel and a tire bead, and thereafter releasing the tire from the wheel. The provided is a lubricating agent for mounting or releasing a tire bead allows mounting a tire easily onto a wheel, at a bead seating pressure of 300 kPa or less; leaves little residual component after mounting; and enables easy releasing of a tire from a wheel. The present invention provides a tire and wheel assembly method and dismantling method in which the lubricating agent for mounting or releasing tire beads is utilized.

A tool for breaking a bead of a tire from a wheel rim includes a clamping device and prying device. First and second jaws of the clamping device clamp onto the wheel rim. As the jaws clamp together, the second jaw wedges between the tire and wheel rim, forming a gap therebetween. The second jaw includes a hook that provides a fixed leverage point when the clamping device is fixed in place. The prying device engages with the fixed leverage point, and a wedge disposed on a bend in the prying device is wedged into the gap formed by the clamping device. The prying device is then levered on the fixed leverage point toward the tire so that the wedge pushes on an outer surface of the tire to break the bead of the tire from the wheel rim.

Described herein is a wheel rim clip or clamp that is used to assist the user in mounting or remounting a bicycle tire on a wheel, thereby allowing the user to use both hands in mounting the tire around the wheel (tubeless or a tube/inner tube assembly). Furthermore, the rim clip allows a user to mount or remove a tire from a wheel rim with or without a work stand.

A tire changer which utilizes an elongated bead breaker assembly with a tool that defines a pair of contiguous, substantially planar tire contact surfaces which define therebetween an included angle in the range of about 155 to about 165 degrees. The tool is situated at an included angle of about 55 to 65 degrees with respect to longitudinal axis of the elongated bead breaker assembly.

The present invention relates to a device for mounting tubeless tire comprising an elongated balloon having an opening attached to a bicycle tire valve. The balloon is fabricated from latex or any other suitable elastic material, and is filled with a tire sealant composition. Further, the ballon is designed to burst at a pressure of 15-40 psi.
