Abstract: A rolling assembly includes a rim and a unit that can be slid axially onto and off the rim. The unit includes the tire and a collar on which the tire is mounted. The collar includes opposite collar hooks interconnected by a reinforced central portion of the collar. The hooks receive respective tire beads. When the tire is at reduced pressure, the unit can be inserted onto the rim. Upon inflation of the tire, a blocking portion of the tire enters a groove of the rim to axially lock the tire onto the rim.

Abstract: An assembly of a rim and a closed toroidal tire. The tire includes a tire casing and a ring, defining a tight chamber. The ring provides a mounting base on the rim and forms a sleeve designed to rest on said rim in mounting position. The ring includes a protuberance having a locking surface, intended to be engaged in a complementary groove arranged on the rim in order to oppose any relative movement between tire and rim axially in at least one direction. The ring has such a degree of flexibility that a pressure reduction of the chamber causes a displacement of said protuberance toward a larger radius. The tire can, for example, be fitted on the rim, and then the vacuum can be eliminated so that the protuberance will be engaged in the groove.
