Abstract

An assembly comprising a wheel (200) and a non-pneumatic tire (300) is disclosed. The non-pneumatic tire (300) comprises a plurality of helical springs (315), each helical spring (315) comprising a first end portion, a second end portion, and an arching middle portion. Each helical spring (31) is interlaced with at least one other helical spring (315) thereby forming a laced toroidal structure extending about an entire circumference of the non-pneumatic tire (300). The first end portions of a plurality of helical springs (315) are directly secured to a first annular structure of the wheel (200) and the second end portions of the plurality of helical springs (315) are directly secured to a second annular structure of the wheel (200). The first end portion of each of the plurality of helical springs (315) are oriented coaxially with the second end portion of each of the plurality of helical springs (315). The plurality of helical springs (315) are constructed of a material that maintains strength and ductility down to 17 K.
