The rim fails in column buckling at the spoke holes from the
compressive load. the valve hole in some rims being the weakest
location. That's why the rim goes into a buckling "S" bend, being
constrained by the spokes from any single large lateral excursion as a
free standing column (pole vault pole) would.
