I have already posted this before but did not get any response. Can anyone give me the answer please. I'm waiting to by new rim for my 240 thanksmy fellow benz brothers and sisters.

 

go over to www.tirerack.com put in your make modle and year and it will show you everything. 18 should work fine.

 

I've 18X8.5 in the front and 18X9.5 in the rear and work great, the only thing is you may need a 1/8" speacer in the front depending on the offset of the wheels. I bought Ruff Racing and they fit perfectly without a issue, by the way if you need tires size and pictures just PM me and I'll email it to you.
