  "textContent": "A non-pneumatic tire defining axial, radial, and circumferential directions. The tire includes an annular lattice structure extending radially between an inner circumferential edge and an outer circumferential edge. The lattice structure exhibits topological polarization, with the inner circumferential edge being stiffer than the outer circumferential edge. The topological polarization includes asymmetry in mechanical response to opposing forces applied to the inner and outer circumferential edges. The lattice structure which provides topological polarization endows the tire with localized softness along the outer radius, which enables extreme absorption of asperities, without transferring significant forces to the axle. In some embodiments, the lattice structure further exhibits topological protection, including the topological polarization characteristics being maintained upon experiencing wear at the outer circumferential edge. In some embodiments, the lattice structure is, or is akin to, a Kagome lattice arrangement.",
