The Third Revolution of the Wheel: A Structured Metamaterial, Digital, and Intelligent Platform for Future Mobility

This white paper presents MetaTire™ / n-Wheel™, a non-pneumatic (airless) wheel–tire platform based on architectured cellular and mechanical metamaterial design. The system integrates auxetic structures with negative Poisson’s ratio, multiscale mechanics, and digital twin–based simulation to achieve enhanced structural stiffness, vibration suppression, and improved vehicle dynamic performance.

Modal and NVH analyses demonstrate significantly elevated eigenfrequencies compared with conventional pneumatic tires, indicating distributed load transfer, reduced deformation localization, and improved drivability and vehicle stability. The proposed MetaTire platform is intended for electric vehicles, autonomous vehicles, and future intelligent mobility systems, and is developed using the Digital n-Wheel framework.
