Greetings. 1999 SL500 owner and I find the car a little boring. Looking to change out the wheels to something more current. I have the bolt pattern but wonder how large a tire can I shoe horn in there. Is 18" too large? Really like the wheel on the C330-350 2015-2018. I think the rear wheels are larger than the front. Very new to Mercs so excuse me for stumbling a bit. Just want to make my car hot.

 

I went to 245 40 18 on aftermarket Mercedes wheels I found on Ebay. You can see them in my album
