Depends on what you want. If you get smaller rims so you can mount a tire with a larger aspect ratio, and end up at the same diameter, nothing changes. If your diameter does change then the only thing you have to worry about is that the speedometer is now off. That is an easy fix if you own a real tuner, but one of THOSE is probably $400. If it is for limited driving during the winter, probably easier to just leave it alone. But if you did have a tuner, you get someone to write a tune or two for the car to really make it rock...
