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.

A device (1) for mounting and demounting a tyre and a method of preparing a device for mounting or demounting a tyre are proposed, wherein said device (1) has a main body (2) and a bead breaker element (5), said main body (2) having at least one rail (3), with at least one of said rails (3) having at least one lockable running rail (5) arranged thereon, and said bead breaker element comprising a bead breaker blade (10), a bead breaker arm (9), and a lever element (11), and wherein said device (1) comprises at least one support (8, 17), with at least one of the supports (8, 17) being detachably fastenable to at least one running rail (5), which makes it possible for tyres of different wheel types to be demounted from the wheel rim or mounted onto the wheel rim.

A wheel rim clamping device, which has a base, three clamping jaws, a linkage mechanism, and a drive mechanism. The base has a vertical tube and three guide rods arranged horizontally and radiating at equal angles from the vertical tube. Each of the clamping jaws is slidably and correspondingly mounted on one of the guide rods. The linkage mechanism has a triangular plate rotatable around the vertical tube and three curved rods, respectively, provided corresponding with the clamping jaws, wherein one end of each curved rod is pivotally connected with the corresponding clamping jaw and the other end of each curved rod is pivotally connected with the triangular plate. The drive mechanism has a nut fixed on one of the clamping jaws and a screw rod provided on one of the guide rods and screwed to the nut.
