Abstract: A non-pneumatic tire for a wheel comprising a hollow inner tube, an outer casing completely encasing the inner tube, and an elongated flexible element tightly tied within the inner tube. The tire can be made by forming an opening in the wall of the inner tube, inserting an elongated flexible element through the passage of the inner tube, deforming the inner tube and tying the end portions of the elongated flexible element together through the opening with the tube in its deformed configuration. The opening is then sealed and the outer casing is molded around the inner tube.
