Abstract
A tube tire capable of simply, positively preventing the generation of a puncture due to contact of opposing portions of the wall surface of a tube. Double wall portions are formed at rim striking portions of a tube contained in a tire, and the internal spaces of the double wall portions are filled with a sealant. When the tire rides over an obstacle and the tire and the tube are clamped between the flange portions of a rim and the obstacle, the shock is damped by the double wall portions to prevent damage of the tube. Even if the double wall portions are damaged, the damaged portion is repaired with the sealant, thereby eliminating the generation of leakage of air.
