Designed By NASA For Mars Rovers, These Airless Bike Tires Will Never Go Flat

One company might have the solution to that dilemma, as it is building a flat-proof non-pneumatic tire, using NASA-designed materials that were originally envisioned for use on Mars rovers. The SMART Tire Company’s METL™ tire is said to deliver a smooth ride and have “superior handling & durability.” The METL tire is made from Shape Memory Alloy Radial Technology (SMART), a superelastic material called NiTinol+, which “rearranges its molecular structure when you bend it, but instantly goes back to its original shape, perfectly.”
