Attention bicycle lovers! Tires that never go flat are no longer the stuff of future films. Thanks to technology developed by NASA for its rovers on the Moon and Mars, Ohio-based Smart Tire Company has developed Metl tires, now available through a Kickstarter campaign.
Really out of air?
Although the term “airless” can cause confusion, these tires are not completely empty. They contain air, but it is not under pressure. This means they don’t need air to keep their shape. Imagine one less problem when traveling by bike.
Technology and design
At the heart of these innovative tires is a structure reminiscent of the famous “Slinky” toy, a kind of spring that surrounds the entire rim. This spring is made of a nickel-titanium alloy called NiTinol. This material is as strong as titanium, but with the elasticity of rubber.
Because it’s important? NiTinol has the ability to return to its original shape after pressing. This feature allows the Metl tire to compress and regain its shape, creating a ride that is as smooth as a traditional pneumatic tire.
Efficiency and durability
It’s not just cutting-edge technology, but also sustainability. Metl tires use only half the rubber of a conventional rim. And although the tire tread needs to be replaced after a ride between 5,000 and 8,000 miles, the main tire could last the life of the bike!
To launch, Smart Tire Company is offering road and gravel tires in sizes 700 x 32c, 35c and 38c. The 35c model weighs around 450 grams, which is the average weight of conventional pneumatic tires.
It says that future versions of these tires will allow users to adjust the firmness by adding more air. Although they remain semi-pneumatic, the air will never completely deflate.
If you’re thinking about purchasing a set of these tires, you can secure a pair with a $500 donation. And if you need to replace the drawing, it will only cost you about $10. Delivery is of course scheduled for next June. So have a little patience!
