I run 225/55/16's on the front, and 245/50/16's on the rear. Unless you use spacers going any wider would be quite tight, well it's going to be tight either way. You would really need SLS in the rear to go any larger, because if you load the car down the rubbing would be wicked.

Depends on the offset of those wheels to. You might have to go with like a 215/60.

Nice wheels! The chrome center caps are a little bright for my taste. I would use the MB chrome centers where its just the star, than paint around that black to match the wheels.
