General Motors (GM) and French tire manufacturer Michelin announced a partnership for a new airless wheel called the Tweel. Actually, tire manufacturers have been working on airless wheels for decades but apparently, no one has really knocked it out of the park yet. And to be clear, the Tweel already exists but it’s mainly in use for forklifts and lawn mowers and low speed engines. But first of all, what exactly is a Tweel? According to wikipedia:

“The Tweel … an airless tire …  Its significant advantage over pneumatic tires is that the Tweel does not use a bladder full of compressed air, and therefore cannot burst, leak pressure, or become flat. Instead, the Tweels hub is connected to the rim via flexible polyurethane spokes which fulfil the shock-absorbing role provided by the compressed air in a traditional tire.”

Enter the new partnership between GM and Michelin who have partnered under the brand name Uptis. From the join GM/Michelin press release in Montreal:

“Uptis demonstrates that Michelin’s vision for a future of sustainable mobility is clearly an achievable dream. Through work with strategic partners like GM, who share our ambitions for transforming mobility, we can seize the future today. General Motors is excited about the possibilities that Uptis presents, and we are thrilled to collaborate with Michelin on this breakthrough technology. 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.”

Okay. Sounds great. Also, the Tweel tread lasts longer and is replaceable which means much less waste. And I’ve had a tire blow up from hitting a pothole, and, probably just like you - had some tires punctured by nails and whatnot. Buying new tires sucks. So, when can I have one of these new fancy airless tires?

Alas … not until, maybe, 2024. Which sucks because I hate waiting. The other problem is that no one seems to know exactly how much they’ll … well … you know - cost. I mean, I’m one hundred percent on board for the airless tire revolution! But if the Tweels are, say - one thousand dollars each, then I might just have to stick with my trusty old air filled tires. Even if that makes me one of the uncool kids.

But whatever, I’m used to that by now.

Just bring me my airless tire at an affordable cost. That’s not so much to ask. Is it?
