Abstract: The tube material 2′ extrusion-molded by the extrusion molding machine has an air chamber peripheral wall 3i, a sealant chamber peripheral wall 3o and a partition wall 4. An air chamber 5 is defined between the air chamber peripheral wall 3i and the partition wall 4, and a sealant chamber 6 is defined between the sealant chamber peripheral wall 3o and the partition wall 4. On the air chamber peripheral wall 3i are protrusively formed a plurality of rib-shaped projections 15 each forming a thick portion for reinforcement. The thickness t3 of each of the projections is approximately equal to the thickness t1 of the peripheral wall 3 and the thickness t2 of the partition wall 4.

Abstract: In a tube whose internal space is partitioned by a partition wall to formed an air chamber filled with air and a sealant chamber filled with a sealant, the ratio R (R=B/A) of the length B of an outer circumference of the tube accommodated in the tire and expanded by filling of air to the length A of an outer circumference of the tube in an unexpanded is set in a range of 100% to 110%. Thus, the tension of the partition wall at the time when the tube has been expanded is suppressed to a small extent. Even if the partition wall of the tube gets a punctured wound, the partition wall having only a small tension applied thereto has a weak tendency to be intended to be contracted toward the air chamber. Therefore, little, if any, of the air in the air chamber flows into the sealant chamber and thus, a reduction in sealing performance of the sealant due to the mixture with the air is prevented.
