Michelin and General Motors recently presented a new generation of airless wheel technology, the MICHELIN Uptis Prototype (or "Unique Puncture-proof Tire System") for sustainable mobility. GM intends to develop this airless wheel assembly with Michelin and aims to introduce it on passenger vehicles as early as 2024.

Later this year, GM plans to initiate real-world testing and validation of the Uptis Prototype on a Michigan test fleet of Chevrolet Bolt EVs.

"General Motors is excited about the possibilities that Uptis presents, and we are thrilled to collaborate with Michelin on this breakthrough technology," said Steve Kiefer, senior vice president, Global Purchasing and Supply Chain, General Motors. "Uptis is an ideal fit for propelling the automotive industry into the future and a great example of how our customers benefit when we collaborate and innovate with our supplier partners."

Airless technology makes the Uptis Prototype eliminate flats and blowouts. This means Uptis offers significant potential for reducing the use of raw materials and waste, contributing to GM's vision for a world with zero crashes, zero emissions and zero congestion as it:

• Reduces the number of punctured or damaged tires that are scrapped before reaching the end of their life cycle.
• Reduces the use of raw materials, energy for production and emissions linked to the manufacture of spare tires and replacement tires that are no longer required.
• Lasts longer by eliminating irregular wear and tear caused by over- or under-inflation.
• Reduces dangers related to flats and blowouts.
