NASA-Inspired Bicycle Tires That Never Go Flat Could Last a Lifetime

A tire startup has teamed up with NASA to bring the world’s first spage-age alloy bicycle tires to the mainstream market. The SMART Tire Company recently announced an innovative airless bicycle tire originally developed and tested by NASA for future Mars Rover missions. Dubbed METL, the revolutionary tire is made from smart memory metal that — unlike stretching — rearranges its molecular structure when you bend it, but instantly goes back to its original shape. It basically has the flexibility of rubber but is as strong as titanium, which means that you probably won’t have to change another bicycle tire in your lifetime. The SMART Tire Company’s METL tires are expected to hit the market in 2022, and while there’s no information on pricing, it’s safe to say they’ll cost a bit more than traditional bicycle tires.
