One might believe that the innovative staff at NASA's Glenn Research Center is looking a little too "Game of Thrones" based on their new tire that looks more like a gentleman's armor than a tire .

The last tire, the superelastic tire, represents an evolution of the spring tire of the US space agency that was originally invented in 2009 through a collaboration between NASA and Goodyear inspired by the lunar tires of the Apollo mission.


The new Superelastic Tire was developed taking into account future Mars missions, but NASA says in a press release that it could serve as a potential alternative to the pneumatic tires in use here on Earth.

"The novel use of shape memory alloys capable of undergoing great stress as load-bearing components, instead of typical elastic materials, results in a tire that can withstand excessive deformation without permanent damage," writes NASA in a statement. "Using shape memory alloy as radial stiffening elements can also increase the load capacity of the tire.

" The super-elastic tire offers equal or superior traction to conventional pneumatic tires and eliminates the possibility of puncture failures, improving thus the safety of the automobile. This tire design also eliminates the need for an interior frame that simplifies and lightens the tire / wheel badembly. "
