Self-sealing tire

A self-sealing tire comprising:

• a) a tire body that is made of flexible and airtight material and is adapted to be assembled with a rim;
• b) a partition wall;
• and
• c) a sealant that is adapted to seal a puncture in the tire body;
• wherein the tire body has a circular shape, and comprises a outer circumferential wall that is adapted to contact the ground, a first side wall and a second side wall that extend from the outer circumferential wall, wherein the partition wall is provided between the first side wall and the second side wall and defines a partitioned space between the outer circumferential wall, the first side wall, the second side wall and the partition wall, wherein the sealant is filled in the partitioned space,
• wherein the partition wall comprises a partition membrane,
• wherein the partition membrane comprises a first edge that contacts the first side wall, and a second edge that contacts the second side wall, wherein the partition membrane forms an annulus that is concentric with the tire body,
• wherein the partition wall further comprises one or more dividing projections that are protruded from the partition membrane,
• wherein the dividing projections of the partition wall contact with the outer circumferential wall of the tire body,
• wherein each of the dividing projections forms an annulus that is concentric with the tire body,
• wherein the dividing projection comprises one or more communication holes whereby the sealant may flow through the communication holes.
