A multi air chamber tire 1 includes a tread portion 4, a pair of bead portions 2, a pair of sidewall portions 3 extending between the tread portion 4 and the pair of bead portions 2, and partition walls 30 respectively provided to half portions of a tire which are defined with respect to a tire equator plane, the partition walls 30 partitioning an inner cavity of the tire to form a plurality of air chambers disposed adjacent to each other. Each of the partition walls 30 includes a first coupling portion 9a coupled with a tire inner wall surface, and a second coupling portion 9b coupled with the tire inner wall surface at a position outward of the first coupling portion 9a in a tire radial direction. In a state where the tire 1 is filled with fluid, a first air chamber 20 is formed in a space located at a position inward of the partition walls 30 in a tire width direction, and a second air chamber 21 is formed in a space located between a partition wall of the partition walls 30 and the tire inner wall surface of a sidewall portion of the pair of sidewall portions 3.
