Will this size of wheels fit 2008 C300 Sports stock tires. I was told that I would need spacers. If so than what size would I need. Thank you in advance.

 

You forgot to tell us the size of the wheels or atleast i cant see them. lol

 

I wrote it but for some reason it didnt show up.. Lol.. Sorry

Size 17 x 7.5
Bolt pattern 5 x 112
Offset +32mm

 

It's actually there in the original post... only the font is *white*. Look closely and you can see it.
Anyhoo, the wheels will NOT work. Offset is too low as-is, making them already poke out too far. Spacers would only push them out further. Offsets work opposite of your thinking, e.g. a lower number means further out and a higher number means going in toward the wells.
