Wheels and tires make a huge huge difference on the margin for cars that are already pretty efficient. But Tesla doesn't ship particularly efficient wheels and tires from the factory, do they? When I was shopping for them they seemed to universally ship all-season performance tires, not the kinds of efficiency tires you see on other EVs and hybrids. I assumed that they were doing that because the rest of their platform is already so much more efficient than others. The big wheel package available on my hybrid kills the MPG, and I am happier with the 16" wheels. But Tesla doesn't offer anything under 18" as I recall.
