ABSTRACT:
To provide a tire which allows the motor vehicle to continue operation even when both a tire body thereof and a tube mounted therein are damaged. A tire houses therein a tube which is compartmented into an inner circumferential air chamber filled with air and an outer circumferential sealant chamber filled with a sealant. The tire has lateral beads held and hermetically sealed against lateral steps of a rim. Even when the tube is pierced, the sealant repairs the pierced hole, preventing air from leaking out. Even if air leaks from the tube into the tire body, because the pierced hole in the tire body is repaired by the sealant and the beads, of the tire body are sealed against the rim, the air is prevented from leaking out of the tire body.
