GM and Michelin will bring airless tires to passenger cars by 2024

Posted by in category: transportation

Circa 2019


Airless tires for everyday cars might soon be far more practical. GM and Michelin have unveiled a prototype of Uptis (Unique Puncture-proof Tire System), a Michelin-made tire intended for passenger cars. It looks like Tweel and other air-free concepts of years past, but its mix of composite rubber and resin embedded fiberglass lets it operate at highway speeds — earlier options tend to work only when you’re slowly putting around. It’s not as visually appealing as conventional tires, but Michelin claims it’s just as comfortable.

More importantly, there’s a tangible roadmap. GM will start testing the Uptis in Michigan later in 2019 on a fleet of Chevy Bolts, and expects the finished version to reach production cars as soon as 2024. The automaker hasn’t named specific car models that will use the new tires.
