Assembly comprising a tire, a collar and a wheel rim

摘要

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.
