Do not know where you as that might impact on how many sets of tires/wheels you use.

If you do have a winter, two sets of wheels/tires are the way to go. One set of V-rated and the other snow. I believe V-rated tires are the recommended ones for your car in the summer.

If you do not really have a winter (light snow once or twice a year, like Hotlanta, LOL), then some M+S H-rated tires might be good compromise.

If you still have the original 15-hole wheels, then some replica 8-hole or AMG look alike are good ones to get.
