Bridgestone Debuts Second-Generation Lunar Rover Tire for Extreme Space Conditions

Bridgestone Corporation revealed its advanced second-generation lunar rover tire during the 39th Space Symposium, held from 8–11 April 2024 in Colorado Springs, USA. Featured in the Japan’s Space Industry booth, organized by JAXA (Japan Aerospace Exploration Agency), the tire demonstrates Bridgestone’s technological advancements in space exploration.

This new tire incorporates “Air Free®” technology, inspired by camel footpads, for improved traction on the moon’s regolith. The tread, crafted from soft, metal-based felt, provides superior grip, while thin metal spokes and segmented tread structures enhance durability and maneuverability.

Advanced simulations helped optimize the skeletal structure, ensuring flexible yet durable metal spokes. This design increases the contact area, prevents sinking, and improves overall performance, addressing challenges like rocky terrain, vacuum conditions, and extreme temperature shifts on the moon.

Bridgestone’s ongoing project aligns with its 2024–2026 Mid Term Business Plan, which emphasizes innovation in mobility solutions. Drawing from its motorsport expertise, the company aims to push the boundaries of lunar mobility while exploring potential applications for Earth.

The “Bridgestone E8 Commitment” guides this initiative, focusing on mobility innovation and sustainable technology. The project also reflects Bridgestone’s ambitions to expand its influence in the global space sector.

The second-generation lunar rover tire represents Bridgestone’s evolution in engineering, supporting lunar missions designed to deepen humanity’s understanding of the moon and beyond.
