The NASA rim is designed to be stiff both laterally and radially. Based on an I-beam design with extra thick tapered sidewalls, tapered spoke seats, cross over lacing and a curved inner strut.

The NASA rim is constructed from space age 6066-T6 aluminium which is much stronger than the cheaper 6061 alloy traditionally used in most rims (+34% tensile strength vs 6061-T6). Intergalactic...
