Abstract
A multi air chamber tire 1 includes a partition wall 30 configured to define and form a plurality of air chambers 20 disposed adjacent to each other in an inner cavity of a tire, and a ventilation member 10 provided to the partition wall 30, and configured to connect the plurality of air chambers 20 in a state where ventilation is allowed. The ventilation member 10 allows ventilation between the plurality of air chambers 20 when a predetermined condition is satisfied indicating that fluid is being injected into at least one of the plurality of air chambers 20 from outside of the tire, and the ventilation member 10 shuts off the ventilation between the plurality of air chambers 20 when the predetermined condition is not satisfied.
