Abstract: An apparatus for mounting tires in bicycles, motorcycles, includes at least one main frame and at least one support provided with a seat whose shape and dimensions are complementary to those of the hub of a rim of a wheel of a vehicle for temporary accommodation thereof. The support is integral with the main frame. The apparatus includes at least one pair of jaws that are integral with the main frame; at least one element for the mutual clamping of the jaws; and at least one portion of the lateral surface of the tire is interposed between the ends of the jaws subjected to clamping. In this configuration, the portion is compressed transversely to facilitate the arrangement of the bead of the tire within a respective receptacle of the rim, which is rotatably coupled with respect to the seat and therefore also with respect to the jaws.
