Catelo

First off I am newbie, both to this board, and to being a MB owner. Great site..

A buddy of mine is giving me these wheels in 18". He had them on his BMW but is not useig them anymore. All I have to do is go get them out of his shop and put some new tires on them. I was thinking of putting a 45 series tire on it so that it does not take away from the ride quality too much. What do you guys think.
