I lost track of what is trying to be proved here?  Rolling radius is 
real. That is the distance between the axle centerline and the road 
surface. That distance is what determines the tractive force at the 
surface.   A deflated tire will have to make more revolutions to go the 
same distance as one that is inflated. It is kinda like an orbit. Speeds 
and velocities change on the rim with radius to the orbit path.  Look at 
a tank's tread...many radii at all kinds of points on it.

What was being proved ot talked abotu here, lol..
