We are still analyzing the data and will publish the results when we have some conclusions. As sometimes happens in testing programs, the results are really different from what we expected and we are trying to understand what we have seen.

I am really curious to see this paper, we're currently in process on comparing a variety of wheels for static friction levels, all 3" due to what we had on hand,
gum rubber roughtop
nitrile roughtop
SBR roughtop
Colsons
Colsons with a tread pattern applied
all similar size 3" diameter around 7/8ths wide

It'd be nice to have some more data to look at, I like data
