What are you asking about -zero rolling resistance????

Providing givens is common when asking for a calculation. By
suggesting zero rolling resistance, I was trying to make it easier
or at least achievable for anyone who has a clue. The fact that
you do not have a clue is useful information, but I could have
figured that out without your babbling.
