    Abstract: A rim assembly for a tire includes an outer rim having an outer annular surface and an inner surface. The rim assembly also has an inner rim with an outer surface, wherein the inner surface of the outer rim has a first plurality of axial grooves that define a first plurality of axial ridges. The outer surface of the inner rim has a second plurality of axial grooves that define a second plurality of axial ridges. The second plurality of axial grooves have a cross-sectional geometry corresponding to a cross-sectional geometry of the first plurality of axial ridges, and the second plurality of axial ridges have a cross-sectional geometry corresponding to a cross-sectional geometry of the first plurality of axial grooves.
