Abstract
A tube tire for avoiding damage to a tube in charging a sealant, and for preventing the sealant from plugging an air valve of the tube. A first tube half and a second tube half have the same side and circular cross sections are joined together as raw rubber, and then vulcanized, thereby forming a tube consisting of the two tube halves and integrated in a seamless condition. An air chamber is defined in the first tube half, and a sealant chamber is filled with a sealant and is defined in the second tube half. When the tube is pierced, the sealant repairs a pierced hole to prevent the puncture. Further, the air chamber is separated from the sealant chamber, so that an air valve provided on the air chamber is not plugged with the sealant.
