A non-pneumatic tire includes a lower ring having a first diameter and an upper ring having a second diameter greater than the first diameter. The upper ring is substantially coaxial with the lower ring. The non-pneumatic tire further includes a plurality of curved, steel spokes extending between the lower ring and the upper ring. Each of the plurality of curved, steel spokes has a 0.2% yield strength of at least 1300 MPA, a tensile strength of at least 1400 MPa, and a hardness of at least 50 HRC.

    Un pneu non pneumatique comprend une bague inférieure ayant un premier diamètre et une bague supérieure ayant un second diamètre supérieur au premier diamètre. La bague supérieure est sensiblement coaxiale par rapport à la bague inférieure. Le pneu non pneumatique comprend en outre une pluralité de rayons d'acier incurvés s'étendant entre la bague inférieure et la bague supérieure. Chacun de la pluralité de rayons d'acier incurvés a une limite d'élasticité conventionnelle à 0,2 % d'au moins 1300 MPA, une résistance à la traction d'au moins 1400 MPa, et une dureté d'au moins 50 HRC.
