Document Type and Number:
WIPO Patent Application WO/2022/239282
Kind Code:
A1
Abstract:
The problem addressed by this invention is associated with providing a non-pneumatic tire which achieves both ride comfort and durability despite having a small diameter size. The solution therefor is a non-pneumatic tire (1) using a resin composition as a framework member, the non-pneumatic tire (1) being characterized in that a bending modulus of elasticity at −20°C compliant with ISO 178 of the resin composition is 247 MPa or less and a bending modulus of elasticity at 60°C compliant with ISO 178 thereof is 32 MPa or more, and a diameter D in the tire radial direction is 35 cm or less.
