No air.
Pressure replaced with material
No flats.
No air to lose
Retreadable.
Renew the tread, keep the structure
01 / The core insight
For 100 years, tires have run on air pressure. Pressure is also how they fail.
A pneumatic tire uses air to carry load, absorb shock, and return energy. One puncture collapses all three. A century of mobility built on a single fragile dependency.

02 / Reinventing the tire®
We replaced air pressure with the right material.
Foam and polymer airless tires were heavy and rough. Our Nitinol structure does what air does, elastic like rubber, strong like metal, recovering instantly under load. A new architecture, not a better tire.
Nitinol, nickel + titanium. A shape memory alloy.

The METL bicycle tire is coming.
Over 20,000 riders are already on the waitlist.
03 / Validation
From NASA validation to commercial launch.
Proven through paid programs with partners across aerospace, automotive, and mobility, including a CES 2025 proof-of-concept with Hyundai and Kia. Our first consumer tire is in active evaluation with a leading micromobility operator, with a waitlist already past 20,000 riders.

05 / Origin · NASA
It began as a tire for the Moon & Mars.
Our shape memory alloy structure was developed through NASA research for interplanetary mobility, a load-bearing wheel that crosses rock and crater without air, in temperatures no rubber could survive. That same technology is what we're now bringing to every road on Earth.

06 / Why now
For the first time, the material, the cost curve, and the market are aligned.
Beyond Air™.
Material, cost, and market have finally converged. A genuinely new approach to the airless tire — built on advanced materials, not air — is no longer a question of if, only how fast. We're building it now.
Tires are just the beginning.
The material that replaces air in a tire replaces it everywhere load meets the ground: across mobility, automotive, and aerospace.
