A method for changing a pneumatic tyre (P) and a support element (S) inside said tyre on a monobloc wheel rim (J) comprising a first and a second seat for said wheel rim, whereby the two seats of the wheel rim are slanted outwards and are axially and externally extended by means of low projections. The inventive method consists in arranging a wheel change insert (I) in the form of a circular ring with a low dimension triangular meridian section in a lubricated void between the tip of the first bead of the tyre (B¿1?) and a corresponding seat, whereupon the first bead (B¿1?) is removed from the wheel rim (J) either before or at the same time as the pneumatic tyre/support unit is also removed.
Un procédé de démontage d'un pneumatique (P), et de l'appui de soutien (S) qui lui est intérieur, de la jante de montage monobloc (J), comprenant un premier et un deuxième sièges de jante, lesdits deux sièges de jante étant inclinés vers l'extérieur et prolongés axialement à l'extérieur par des saillies de faible hauteur, consiste à insérer, dans un interstice lubrifié entre la pointe dudit premier bourrelet B¿1? et le siège de jante correspondant, un insert de démontage (I) sous forme de portion d'anneau circulaire à section méridienne triangulaire de faibles dimensions, et à ensuite éjecter le premier bourrelet B¿1? hors de la jante (J) avant ou simultanément à l'éjection de l'ensemble pneumatique-appui.
