I'm with Adam, it is all about unsprung and rotational weight. I put some heavy 19s on my C55 and noticed the difference immediately. The car felt a bit slower to respond off-idle and low RPMs and a bit heavier in steering, too. Overall, less nimble, not that a C55 is the most nimble car to begin with.

Good luck in your decision.
