Unless you leave the heavy tire/wheel combination off the car, sitting on the ground, then they are part of the car and they have to be rotated, doesn't matter where they are, and to the engine it doesn't either. Unsprung weight and suspension dynamics are a whole different thread. Handling would change in cornering. We did this in testing at Road Atlanta on a Formula Ford, two of the tires were mounted on our rain tire steel wheels and we swapped them front to back. There was no diffrence in acceleration, time-to-RPM down the straights were identical. Theres your data; case closed.
