W203/CL203 Aftermarket Wheel Thread - All you want to know
one correction. recommended offset different by width. 8" width on the front depend on the wheel design can go et30-et35. 8.5" width et28-31. 9" width rear et28-38 (higher offset require some rolling of the fender). 9.5/10" width et35.
I am new to the forum and have heard contradicting information from friends about whether my new rims will fit my car or not.
I have a 2005 C Sport so it has the sport suspension and I got an offer to buy some Lorinser LM6 replica wheels. They are 18"x8.5" with ET of 35. I am quite sure they would fit the back but what about the front? Any kind of modifications needed?
Also what tire would you guys recommend? I was thinking 225/40-18 all around but would those fit on the front and then 245/35-18 on the back for a little wider back?
What do you guys think? I called the Mercedes dealer where I live and they just said they can't say unless its an OEM rim. That figures.
Thanks for the help!

@ Casper for reading through the whole thread instead of just asking n00b questions waiting to be spoonfed. The only things I can't completely agree with are the following:- 9" is the max width for the front. Some have managed 9.5" - I've never seen anybody running 9"+ up front without the wheels poking out past the fender.
- Recommended offset is 32-35 - Those offsets are fine for rear wheels 8.5-9.5" wide, but offset and wheel width go hand in hand and must be considered when determining suspension and brake clearance up front. For example, my BBS RG-R's are 8" wide in front with an offset of ET35mm and maybe 1" lip. They have no problem clearing my coilovers, but needed a 12mm spacer to clear my BBK. That brings my offset to ET23mm, which is the same as an 8.5" wide wheel with ET29mm offset in relation to the fender, but an extra 12mm of space between the wheel and suspension. The rears are 9" wide with an offset of ET30mm and about 2" lip which is the same as a 9.5" wide wheel with ET36mm offset in relation to the fender, but an extra 12mm of space between the wheel and suspension. I could easily fit a BBK if I wanted to and have plenty of clearance between the wheel and suspension.
On the other hand,

scroll up and read my short and simple post after casper's long post.
another general rules of thumb: don't try to put wheels that has a lip on the front unless they are forged wheel with custom offset.
and to answer your original question. the LM6 reps 8.5 width ET35 fits. doesn't clear the coilover however. run a H&R 5mm spacer if you plan to run coilovers.

Thanks for your patience and help though FrankW... One more maybe stupid question and then hopefully I can leave you alone. You said that the 8.5 with ET35 fits but doesn't clear the coilovers. All I know is that I have the sport package so I am just running sport "stock" I guess you could say. Are there coilovers in that package or will I then be ok and not need the 5mm spacers?
Also I have gathered from here that the best tire would be 225/40-18 at least for the front. Do you think I'd be safe running a 245 or 255 wide tire on the back?
Thanks again for the patience and help. I'm slowly learning here.

225/40/18 front and you can run either 245 or 255/35/18 for the rear. just your preference.
