Michelin and General Motors talked about it in an interview with CNN Business. They talked about the future of their Uptis airless tire.
We have talked about this several times already, Michelin, the French flagship, has been working on the concept of anti-puncture tires for several years. Research and development of this model began in 2005. The French company has already demonstrated its new product on a real car. Of course, it was the Mini Cooper SE electric car.
What is Uptis?
The Unique Puncture Protection System (UPTIS) is a tubeless tire that, due to its design, does not require air filling and will never puncture.
In addition to the traditional rubber tread, the Uptis tire consists of a load-bearing structure made up of flexible CVR (Fiberglass Composite) sipes that theoretically require no maintenance: re-inflation or air pressure control. . Michelin casually specifies that it will also use 100% recycled and renewable materials for its production chain.
The Uptis wheel combines a lightweight aluminum alloy wheel with a flexible fiberglass reinforced plastic support structure. With this design, this new concept aims to offer the properties of traditional tyres.
The main problem airless tires face is their ability to mimic the strength and flexibility of air filled tires.
Therefore, Michelin strives to take into account all possible configurations, the French company must ensure that different tire models are suitable for different types of vehicles, from sports cars to SUVs and large trucks. Thus, the tire is tested for speed, resistance and endurance. What is the release date?
During an exchange with CNN Business, Alexis Garcin, president of Michelin North America, announced that the brand wants to ” equip the next generation Chevrolet Bolt with airless tires. This should happen within the next 3-5 years. “.
Thus, Uptis tires should be sold between 2025 and 2028.. Michelin and General Motors have been working together for years to develop airless tires, but the interview confirms that the goal is to use these airless tires for Chevrolet’s future electric vehicles. Alexis Garcin said he wants the next generation Chevrolet Bolt to be the first with this airless tire.
Michelin already sells airless tires
Michelin already sells the X Tweel airless tire. This tire is designed for ATVs and lawn mowers. It also gives a first look at practical prices: the X Tweel airless radial tire is integrated and costs more than 1,000 euros.
IN @THOSE In 2022, we introduced the MICHELIN X Tweel airless radial tire prototype for @CoasterCycles delivery of the last mile trike eCargo.

The Uptis and X Tweel tires will have a lot in common, except for the tire design. For “Upti” the center ribs that hold it in place are made of resin-injected fiberglass reinforced rubber.“. X Tweel has polyurethane fins.
Goodyear is also developing airless tyres, but by 2030 the Americans are promising to deliver their first puncture resistant tires.
