Startup Debuts Airless Bicycle Tire Based On NASA Rover Tech

New submitter byennie writes: A new airless bicycle tire called "METL" was introduced today by The SMART Tire Company. The tire is made from shape memory alloys (SMAs) and was originally designed for Mars rover missions (it's headed to Mars in 2026 as part of the Fetch rover). The structural tire claims to be flat-free and high performance, leaning on the unique properties of SMAs developed at NASA for future heavy vehicles in space. According to the company, "the shape memory alloy tire is made from advanced, lightweight materials known as NiTinol+, creating a tire that is elastic like rubber yet strong like titanium, exhibiting perfect shape memory without ever going flat."
