MULTI AIR CHAMBER TIRE

A multi air chamber tire includes a tread portion , a pair of bead portions , a pair of sidewall portions , and partition walls respectively provided to half portions of a tire which are defined with respect to a tire equator plane, the partition walls partitioning an inner cavity of the tire to form a plurality of air chambers disposed adjacent to each other. Each of the partition walls includes a first coupling portion and a second coupling portion coupled with a tire inner wall surface. When the tire is filled with fluid, a first air chamber is formed in a space inward of the partition walls in a tire width direction, and a second air chamber is formed in a space between a partition wall and the tire inner wall surface of a sidewall portion
