Michelin and GM bringing airless tires to the road in 2024
No spare tire? No emergency jack? No flat-tire repair kit? No worries, because these futuristic new tires need no pressure.

Taking the air out of someone is generally seen as a bad move, but when it comes to tires, there are some very real benefits. Michelin has been researching what it would take to bring a pressure-free tire to market for years and now, in partnership with General Motors, the company is saying we might see these Uptis tires on the road as soon as 2024. The two companies announced the product today at the Movin'On Summit for sustainable mobility.

A more reality-based evolution of the company's fanciful Vision Concept Tire, Uptis takes the Tweel airless tire that's already available on commercial vehicles and applies it to a consumer use. Instead of relying on air pressure, the internal composite structure of the Uptis provides all the support the tread needs. (Uptis, by the way, stands for "Unique Puncture-proof Tire System.")

Why is this a benefit? No blow-outs, for one thing. Michelin says that this, plus the reduction in abnormal wear thanks to improperly inflated tires, could provide a major reduction in the 200 million tires scrapped every year prematurely due to damage. Sustainable tires? It's a good first step.

The Chevrolet Bolt EV is the first test car for the Uptis tire.

"But what about performance?" I hear you asking, and that remains to be seen. The first test application for the Uptis will be the Chevrolet Bolt EV, a fun but hardly sporting car. These tires are in fact slightly heavier than traditional run-flats, 50 pounds versus 51 including the wheel, but Michelin says this deficit can be reduced by eliminating flat-tire kits and jacks from production cars.

If all goes according to plan, Michelin and GM hope to have these tires on the road for "select GM models" in the next five years, with other manufacturers hopefully coming on board after that. Compact spare tire, your days are now officially numbered.

Michelin Indestructible Tire | Real life Demonstration about this new Airless Wheel Technology. Michelin and General Motors presented a new generation of airless wheel technology for passenger vehicles — the MICHELIN Uptis Prototype (or “Unique Puncture- proof Tire System”) — at the Movin’On Summit for sustainable mobility. Michelin and GM also announced a joint research agreement under which the companies intend to validate the Uptis Prototype with the goal of introducing Uptis on passenger models as early as 2024. #michelin #tire #uptis

The Uptis Prototype is re-engineered for today’s passenger vehicles, and it is also well suited to emerging forms of mobility. The vehicles and fleets of tomorrow — whether autonomous, all-electric, shared service or other applications — will demand near-zero maintenance from the tire to maximize their operating capabilities. The Uptis Prototype represents a major advancement toward achieving Michelin’s VISION concept, which was presented at the Movin’On Summit in 2017 as an illustration of Michelin’s strategy for research and development in sustainable mobility. The VISION concept introduced four main pillars of innovation: airless, connected, 3D-printed and 100% sustainable (entirely renewable or bio-sourced materials). ⚡ Discover ALL new cars before anyone else!

Goodyear presented a vision of a future tire that looks radically different from tires today — it’s a sphere. Goodyear unveiled its latest concept tire, Eagle-360, at the Geneva International Motor Show. The spherical, 3-D printed tire highlights Goodyear’s vision for the future and presents an inspiring solution for the long-term future when autonomous driving is expected to be more mainstream. According to a recent study from Navigant Research, 85 million autonomous-capable vehicles are expected to be sold annually around the world by 2035, for example. According to the J.D. Power 2015 U.S. Tech Choice Study, consumers are most concerned with ensuring safety through technology in autonomous cars.

Chevrolet Bolt electric testing puncture proof, airless tyres – Video

Developed by Michelin, these new tyres will launch in 2024.



If you have ever experienced a flat, you would know how troubling and frustrating it could be. However, future may not be as unforgiving, as Michelin and General Motors may just have discovered the holy grail of puncture-proof tyres. Working together, Michelin and GM unveiled the Michelin Uptis prototype at Movin’On Summit for sustainable mobility. Short for “Unique Puncture-proof Tire System”, Uptis runs without air, making it puncture-proof and completely free from blowouts.

Uptis utilizes composite materials and advanced architecture, which enable it to bear the car’s weight without the need for compressed air. Uptis has already been tested at road-going speeds and it has delivered remarkable results.

In the next step, Michelin and GM will be testing Uptis in real-world conditions by launching it with cars such as Chevrolet Bolt EV. An entire fleet of Bolt EV cars will be equipped with Uptis and these will be tested in real-world conditions in Michigan.






If the tests are successful, Uptis could go into commercial production by 2024. Although Uptis is punctureproof, it has its own set of challenges such as material fatigue and sagging. Things like shock absorbing capability, driving dynamics, braking, acceleration, and other related factors need to be evaluated before Uptis is finalized for commercial production. Price is another key factor that will determine whether Uptis reaches the masses.

In theory and preliminary tests, Uptis has emerged as a reliable and safe option for car users. The risk of puncture and blowouts is eliminated, which is a significant improvement over standard tyres that use compressed air. With Uptis, vehicle fleets can reduce downtime resulting from flat tyres and blowouts. Uptis is also maintenance free, which is another significant benefit for fleet owners.

Uptis will also help save the environment, as fewer tyres will be scrapped due to punctures and blowouts. Available data indicates that around 20% of tyres are scrapped every year due to punctures or irregular wear caused by low/high tire pressure. Around 200 million tyres are scrapped each year, which creates a huge burden on the environment. Uptis can minimize such wastage and contribute to the cause of environmental conservation.
