Originally invented by NASA for use on lunar and Mars rover missions, there's a new kind of bicycle tire that's elastic like rubber yet strong like titanium. It exhibits perfect shape memory without ever going flat. Essentially, it's the tire of dreams.

Made in gold, silver, and metallic blue, METL tires are made from advanced, lightweight materials known as NiTinol+.

They're the first-ever consumer application of the alloy tire technology NASA will use to get future rover missions out on rough terrain without a hiccup (or puncture). And they're being developed as a partnership with the startup SMART Tire Company.

"Cyclists will not be able to wait to get their hands on these cool-looking, space-age tires that don't go flat," says Earl Cole, former Survivor: Fiji champion and CEO of SMART, in a statement.

"The unique combination of these advanced materials, coupled with a next generation, eco-friendly design make for a revolutionary product."

SMART was founded in 2020 by Cole and blockchain engineer Brian Yennie. Together with former NASA engineering intern Calvin Young, the SMART team has consulted with inventors at NASA Glenn Research Center to bring the power of shape memory alloy tire technology to the general public.
