## Abstract

A self-sealing tire includes a tire body, a partition wall, and a sealant that is adapted to seal a puncture in the tire body. The tire body includes an outer circumferential wall that contacts the ground, a first side wall and a second side wall that extend from the outer circumferential wall. 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. The sealant is filled in the partitioned space. The partition wall includes a partition membrane, and dividing projections that are protruded from the partition membrane. Air is exhausted from the partitioned space and the sealant is filled into the partitioned space.

## Claims

### Claim 1

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.

### Claim 2

A self-sealing tire comprising:
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 a metal partition reinforce member that is provided adjacent to the partition membrane.

### Claim 3 (depends on 2)

The self-sealing tire of claim 2, wherein the metal partition reinforce member has a shape of a plate.
