For roughtop tread, I am going to make an assumption that smaller diameter wheels get more grip as they form more of a sharp cleat than larger diameter wheels do. This cleat is a better shape for interlocking with the rows of carpet fibers.
Making it wider still retains this shape, but increases the width of the cleat.
This is purely based on the anecdotal evidence of our 2008 krab drive running 2" wide wheels.
