<p><P>PROBLEM TO BE SOLVED: To provide a non-pneumatic tire capable of suppressing any circumferential fluctuation of the tire rigidity from occurring according to the positional relationship between the spoke position and the center position of a contact surface, dispersing strain to each part of a supporting structure, enhancing the durability, improving the ride comfort, the noise performance or the like, and sufficiently suppressing the buckling of a ground contact part between spokes. <P>SOLUTION: In the non-pneumatic tire T having a supporting structure SS for supporting the load from a vehicle, the supporting structure SS includes an inner annular part 1, an intermediate annular part 2 provided in a concentric manner on the outside of the inner annular part 1, an outer annular part 3 provided in a concentric manner on the outside of the intermediate annular part 2, a plurality of inner connection parts 4 for connecting the inner annular part 1 to the intermediate annular part 2, and a plurality of outer connection parts 5 for connecting the outer annular part 3 to the intermediate annular part 2. The number of the inner connection parts 4 is larger than the number of the outer connection parts 5. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
