Nasa's puncture-proof tyre, built for Mars rovers, could replace rubber tyres
NASA's Glenn Research Center has developed a puncture-proof, airless tyre using a shape-memory alloy called Nitinol. Originally designed for Martian rovers to withstand harsh terrain, this technology is now being adapted for consumer bicycles.
Why it matters
This innovation could eliminate the need for traditional rubber tyres and maintenance, offering a durable, long-lasting solution for both space exploration and everyday transportation.
For decades, air-powered tyres have been the standard, but they remain vulnerable to sharp stones, nails and air leaks. However, an amazing solution is proposed by Nasa. Imagine you are cycling through the countryside on a crisp morning when suddenly, the dreaded hiss of a puncture ruins your journey.Glenn Research Center has developed a superelastic tyre technology originally designed for the harsh landscapes of Mars and the Moon. By using a remarkable material known as ‘Nitinol’(a nickel-titanium alloy), engineers have created a wheel that never goes flat because it contains no air at all.
