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.
