Looking to replace the wheels on my new to me slk200. (2008) at present it comes with 17 inch wheels and 225 on the front and 245 on the back. Does this mean I have staggered wheels, as replacement sets seem to be 7.5 width. One site is showing in the tyre option I can put either 225 or 245 on the same wheel , is that correct. I like the look of the Monaco gp1 wheel . Thanks Dave.
