I think I understand where your're coming from with this. Although the differences in radial deflection is nearly the same (and presumed to be infinitesimally smaller than what we can sense), what isn't the same is which vibrations are transmitted by the structure. A structure that transmits the road buzz is perceived to be stiffer than one that does not.
