Having read all the forums on wheel size suitability for the 9-5 i'm still none the wiser. I've been offered a set of 18" alloys at a very silly price, the PCD is 5x110, but i'm worried about the offset of ET38. I read saabman's running on 17's with an ET35. My 9-5 is running standard suspension and alloys at the moment (16"). Will 18" wheels wearing 235/40/18 rubber foul the filler pipe? Have seen several sites saying offset of 35-40 is suitable, but concensus on here seems to be stay as close to ET49 as possible Any help will be gratefully received, i've less than 24 hours to make this purchase.
