<p>The invention concerns in particular a method for mounting, on a wheel rim (10), a tyre (600) comprising first and second beads (620, 610) respectively designed to be mounted on first and second seats (13', 13'') of the rim (10) and a safety support designed to be mounted in the tyre on a bearing surface of the rim. Said method comprises the following successive steps: (a) bringing onto the rim the casing provided with the support in its inner space, placing the second bead on the side of the first seat (13'), (b) axially sliding the second bead on the bearing surface so as to insert it into a mounting groove and partly fixing the support on the bearing surface, the first bead being then located axially outside the first seat, (c) slipping on completely the support on the bearing surface, (d) mounting the first bead (620) on the first seat, (e) extracting the second bead from the groove so as to bring it axially outside a protuberance of the second seat (13''), (f) mounting the second bead on the second seat. The invention is characterized in that, prior to performing step (b), it consists in fixing at the base of the groove a means for extracting (510) the second bead and in that, to perform step (e) it consists in guiding the second bead axially outwards of the groove and of the second seat by pivoting the extraction means about a pin (512) located radially inwards of the rim.</p> |
