NON-PNEUMATIC TIRE
First Claim
1. A non-pneumatic tire comprising:
- an attachment body attached to an axle;
a ring member including an inner rim fitted onto the attachment body and an outer rim configured to surround the inner rim from the outside in a tire radial direction; and
a plurality of connecting members disposed between the inner rim and the outer rim in a tire circumferential direction and configured to connect the rims to each other,wherein at least a portion of the ring member and the plurality of connecting members are integrally formed of a synthetic resin material having a bending modulus of elasticity at −
20°
C. obtained through a 3-point bending test that is two times or less a bending modulus of elasticity at 60°
C. obtained through the 3-point bending test pursuant to ISO 178.
