摘要： A tire includes a plurality of SMA springs. Each SMA spring includes a first end portion, a second end portion, and an arching middle portion. Each SMA spring is interlaced with at least one other SMA spring thereby forming a laced toroidal structure extending about an entire circumference of the tire.
