Paul,
How can effective circ differ from actual? I can see that diameter
can be effective or actual because of squish, but do not understand
how circumference is affected.
x inches of road progress is made by x inches of rubber, isn't it?
Seems to me that the wheel moves same distance on the pavement that is
represented by a string wrapped around the wheel.
Is there another factor that I am missing?
