A spherical, short-cylindrical or ring-shaped function air feed-in/feed-out hole is formed at an outer surface of the tube, and projecting navel rubber 5 functionally joined with the tire are provided to form a tube cassette with navel rubber. A control coating film 3 forming a double tire for correcting the shape of the tube to control the tube when feeding air in/from the tube cassette, adjusting air pressure, and performing protection is provided on the entire outer surface of the tube except the navel rubber. An air leading hole piercing from the outer surface of the tire to an inner surface of the tire is formed. A recess is formed in the air leading hole at the inner surface of the tire, the navel rubber projecting part of the tube is joined therewith. Air is fed in the tube through the functional navel rubber of the tube joined through the air leading hole from the outer surface of the tire.
