Abstract
A web structure for a non-pneumatic tire includes a first corrugated ring having a first plurality of peaks and a first plurality of valleys. The first corrugated ring is a metal ring. The web structure further includes a second corrugated ring having a second plurality of peaks and a second plurality of valleys. The second corrugated ring is a metal ring. The second plurality of valleys are affixed to the first plurality of peaks by brazing or welding.

- corrugating the second elongated sheet of spring steel material to form a second plurality of peaks and a second plurality of valleys in the second elongated sheet of spring steel material;
- bending the second elongated sheet of spring steel material into a second annular shape, thereby forming a second webbing ring;
- heat treating the second webbing ring and quenching the second webbing ring in an oil bath;
- affixing the first plurality of peaks of the first elongated sheet of spring steel material to the second plurality of valleys of the second elongated sheet of spring steel material;
- providing an inner ring of spring steel material;
- affixing the inner ring of spring steel material to the first plurality of valleys of the first elongated sheet of spring steel material;
- providing an outer ring of spring steel material;
- connecting the outer ring of spring steel material to the second elongated sheet of spring steel material;
- providing tread rubber;
- and
- affixing the tread rubber to the outer ring of spring steel material.
