Hi all, love the forum and help so far. I have two issues, so I will raise the wheel one first: I have a 1999 (first of the newer shape) w220 Mercedes s320. It came with 16" wheels which looked crazy small. I updated them with 17" wheels from the w221 with 235 /55/R17 Michelin tyres. I am now thinking of a later set of w222 wheels part number: A2224010902; Size: 245 / 50 R18, PCD: 5 x 112 mm, Rim width: 8, Offset: 41 However, I am not sure if the bigger wheels and slightly different offset will cause an issue? I have read on the forum that w222 and w221 wheels should fit the w220 without any issues. Also I believe that 245/50/18 is almost identical tyre size to 245/50/18 too. Can anyone confirm my assumption and what I have read so far? Second issue - my aircon is broken . - but I'll list that under a separate topic. Thanks so much in advance for any guidance on the above.
