Michelin has recently been in talks with Tesla about testing its airless tire technology, known as Uptis (Unique Puncture-Proof Tire System). These discussions took place as recently as April 2024, according to Michelin CEO Florent Megenaux, and could lead to a partnership that could revolutionize the automotive industry by eliminating the risk of flat tires and blowouts in passenger vehicles.

Uptis tires are designed to be puncture-proof, contributing significantly to the sustainability of the automobile industry by saving an estimated 200 million tires from being retired early due to punctures or improper air pressure.
The Uptis tires build on the technology of Michelin’s Tweel, which has been available for non-roadgoing vehicles such as skid-loaders, lawn mowers, and ATVs. Michelin has already partnered with General Motors (GM), testing Uptis tires on a fleet of Chevrolet Bolt EVs since 2021, with the goal to make them commercially available as early as the end of 2024.

One of the significant advantages of Uptis tires is their potential longevity. Michelin claims that these tires could last up to three times longer than standard tires, which would not only reduce tire waste but also lower emissions from tread wear. These tires have also demonstrated positive results at speeds of up to 210km/h (130 mph), making them suitable for high-speed applications such as police vehicles.
Uptis tires are not only lighter but also more aerodynamically efficient than conventional tires. Initial testing on EVs has been positive, suggesting that these airless tires could improve vehicle efficiency by reducing drag and weight.
Michelin is also working on a method to retread Uptis tires using 3D printing technology. This innovation would allow for deeper treads in specific weather conditions and the renewal of old tires, further extending their usability and sustainability.
Additionally, the Uptis tires are expected to have a comparable price to run-flat tires, making them an economically viable option for consumers.
The Uptis is part of Michelin’s broader VISION concept, which focuses on four pillars of innovation: airless, connected, 3D-printed, and 100% sustainable. Michelin and GM are currently working with regulators to obtain government approvals for the Uptis design, with the goal of introducing it on passenger models as early as 2024.
