I just purchased some staggered 18X8.5 and 18X9.5 AMG Monoblock wheels on Ebay. The auction stated that the wheels fit CLK E and S class. Do I need some special lug nuts to put these wheels on a 1992 500 SEL? I read somewhere on this forum that the S class requires different lugware. Is this true? Can I use my original lugnuts with these AMG wheels? Also, what is a good tire size for these wheels. Would 245-40-18 and 275-35-18's work? Thanks for your help.
