Abstract
The device comprises a base for positioning a tire and a lever pivoted on a support and able to move and be fixed in position along a plane which is radial with respect to the center of the base. An active end of the lever, located on an L-shaped bend at an end of the lever, can be introduced internally of the opening to interact contactingly with the internal surface of a part of the support ring pre-inserted in the opening. By acting on the lever, the active end presses the ring against the inside of the tire with radial force. The support ring is of a type which when applied on a vehicle wheel enables the vehicle to continue moving for a considerable time even where tire pressure is suddenly lost.
