Oh yes... you are abso-tively correct.
But you never said that we wanted to look at the dynamics of cornering and directional change on the tire. I was only looking at the physics that affect rolling resistance and cruising effort. Car tires work differently from motorcycle tires (and their little cousins... bicycle tires) in the way that they corner and steer the vehicle.
But the physics of sidewall deflection, contact patch variables, and rolling resistance still hold true for every pneumatic tire on the planet.
