In the grand scheme of things, the difference in acceleration is negligible. You will, however, notice the change in ride quality, especially if the 18s you choose are a lot heavier. People say the change in rotational mass adds greatly to the effect of the extra weight. The math there is correct. Still, when it really comes down to it, the change in the butt dyno is really small IME.
