WIPO Patent Application WO/2019/107305
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a non-pneumatic tire in which the compression permanent strain rate is reduced, whereby tire durability is improved while creep resistance is improved. In order to solve this problem, the present invention provides a non-pneumatic tire provided with a support structure having: an inside annular part; an outside annular part provided in a concentric manner on the outside of the inside annular part; and a plurality of linking parts provided around the tire circumferential direction, the linking parts linking the inside annular part and the outside annular part; wherein at least a part of the linking parts is configured from a resin material for which the degree of swelling after immersion in 80°C N,N-dimethylformamide for one week is 15-70% by weight.
