Space exploration is back in full swing, and Michelin is playing an unexpected pioneer by embarking on the lunar adventure. The French tire giant is no longer sticking to the road: it’s now targeting lunar dust with innovative technology that could well power the wheels of NASA’s future rovers. The year 2025 could mark a turning point in lunar exploration, thanks to a bold partnership combining engineering, space research, and innovative mobility. As NASA prepares its Artemis V mission, an exploration vehicle designed to set foot on the lunar surface, Michelin proudly defended its airless wheel project, capable of surviving in extreme conditions, during a major presentation in Houston. This technical feat echoes the colossal challenge posed by the lunar environment. Between radiation, extreme temperatures, abrasive terrain, and the need for autonomy, the design of these wheels is nothing short of a feat. A full week of presentations to some fifty experts enabled the Moon Racer consortium, led by Michelin, Boeing, and Intuitive Machines, to convince NASA of the maturity and seriousness of this innovation. This project could redefine the standards of space mobility while also driving advances in tomorrow’s ground-based tires.
In this context, both technological and human, we see that the race to equip the lunar rover is not just a competition: it symbolizes French passion and ingenuity combined with an international vision of exploration. Anticipation is therefore palpable for a decision, expected in November 2025, which could propel Michelin into a new era, that of a key player on the Moon. But what are the secrets of this lunar wheel, and how does Michelin intend to transform lunar constraints into technological weapons?

Designing a tire that rolls on the Moon is no easy feat. The lunar terrain is a real nightmare for materials: rocky, powdery, with fine dust that eats up everything in its path. It’s a hostile environment where the temperature can vary between -240 and +100 degrees Celsius, conditions that we obviously prefer to avoid when driving a vehicle on Earth! For the Artemis V mission planned for 2028, the wheel intended for the rover must last for an exceptional duration, i.e. operation over ten years and approximately 10,000 kilometers traveled, much more than the 40 km of the Apollo missions. Michelin therefore chose to break the rules by offering an airless wheel, a technology matured over fifteen years.
What are the major constraints that Michelin must meet for the lunar tire?
🌕 Resistance to solar and galactic radiation – the material must remain intact despite an unforgiving cocktail of radiation.
- 🧊 Withstand the thermal extremes of the Moon (from -240 to +100°C), where traditional rubber would become brittle like glass.
- 🏜️ Resistance to abrasion caused by fine, sharp lunar particles that get everywhere.
- 🚀 Long service life, with reliability over more than a decade in a maintenance-free environment.
- 🏎️ Optimal traction capacity in soft ground, comparable to powder snow where the vehicle must “float”.
- To meet these challenges, Michelin has developed a wheel combining high-performance plastic, as hard as metal, with a flexible structure that provides excellent grip without air. The process also relies on dozens of digital simulations and rigorous tests, notably on the Lemptégy volcano in Puy-de-Dôme and at a European simulation center. Below is a table summarizing the key characteristics of the lunar tire developed by Michelin:

The idea behind this partnership is to combine industrial expertise, robotics skills, and technological innovation to address the unique challenges of deep space mobility. Michelin contributes its expertise in materials and tires, while Boeing contributes its advances in systems engineering, and Intuitive Machines oversees project management and integration. The relationship with NASA is obviously central, as it coordinates the mission and sets the technical requirements. In this extremely competitive playing field, Moon Racer faces two other rival consortia: Lunar Outpost, which includes Goodyear (Michelin’s American competitor), and Venturi Astrolab, another team of specialists. The timeline is tight, with a verdict expected in November 2025, when NASA will select the technical pilot capable of equipping its rover.

Rigorous Testing to Validate Michelin’s Airless Wheel in Lunar ConditionsA fine speech isn’t enough to convince NASA: it needs concrete evidence, and concrete proof (or rather, high-performance plastic). Michelin therefore invested no less than two and a half years in a battery of tests to simulate lunar conditions as faithfully as possible on Earth. Enough to make any airplane pilot dizzy, as you imagine observing the results!
The tests focused on:
🛞 Abrasion resistance and wear of the material under repeated impacts
