Also be interesting to see what sort of degradation in performance when the spokes are packed with dirt/mud

yeah that is what I meant in my post.
A few years ago I remember another brand came out with honeycomb spoke airless tires once these became packed tight with mud or dirt and rock they rather quickly degraded due to abrasion and lack of flexibility.but worked well for warehouse forklift type tires
