Innovators at NASA's Glenn Research center have developed a game changing, non-pneumatic, compliant tire. This innovation, called the Superelastic Tire, was developed for future Mars missions, but is a viable alternative to pneumatic tires here on Earth. This technology represents the latest evolution of the Spring Tire which was invented by NASA Glenn and Goodyear, and inspired by the Apollo lunar tires. The novel use of shape memory alloys capable of undergoing high strain as load bearing components, instead of typical elastic materials, results in a tire that can withstand excessive deformation without permanent damage. Using shape memory alloy as radial stiffening elements can also increase the load carrying capacity of the tire. The Superelastic Tire offers traction equal or superior to conventional pneumatic tires and eliminates the possibility of puncture failures, thereby improving automobile safety. This tire design also eliminates the need for an inner frame which both simplifies and lightens the tire/wheel assembly.
