<P>PROBLEM TO BE SOLVED: To provide a non-pneumatic tire capable of improving braking performance by making a contact pressure distribution uniform at the time of breaking time. <P>SOLUTION: In a non-pneumatic tire T with a supporting structure body SS for supporting a load from a vehicle, the supporting structure body SS includes an inside annular part 1, intermediate annular parts 2 concentrically provided on the outside of the inner annular part, an outer side annular part 3 concentrically provided on the outside of the intermediate annular parts 2, a plurality of inside connecting parts for connecting the inside annular part 1 and the intermediate annular parts 2, and a plurality of outside connecting parts for connecting the outer side annular part 3 and the intermediate annular parts 2. Furthermore, the supporting structure body SS is divided into a plurality of regions S1, S2, S3 in the tire width direction WD, and the maximum diameter D21<SB POS="POST">max</SB>of intermediate annular parts 21, 23 at the outermost regions S1, S3 is larger than the maximum diameter D23<SB POS="POST">max</SB>of the intermediate annular parts 22 at the inside region S2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
