# How do I calculate rolling resistance for tire on pavement?

First condition assuming perfect rolling, no slip, from what I understand is that the rolling resistance coefficient can be calculated as the displacement arm of the normal force the tire "feels", in which should be equal to the force about its center times the radius of the tire (essentially equating two moments?)

I am attempting to do a finite element analysis on a tire, solving for rolling resistance for the tire.

My approach is to take the sum of the shear in the contact patch, multiply it by contact area to result in total tractive force (Fundamentals of Vehicle Dynamics). If this force is then subtracted by static friction, shouldn't this result in total rolling resistance force?

Not sure if my conceptual understanding is correct.

What are industrial ways of getting rolling resistance of tires?

Regarding your comment on static friction, I would just point out that static friction is what generates the torque that rotates the tire, it should not contribute any losses to the rotation (remember that the normal force is $g\cos{\theta}$). Remember that work (energy) is force times displacement, and so, if the tire does not slip, the static friction force doesn't act on any distance, so no energy is dissipated.
