I read somewhere in the forum people advising against putting +20" wheels on a G550/500. I see many people converting their G550/500 look to a G63, which includes larger wheels.

Those people never mentioned rubbing of any sort! Are they using special non OEM AMG wheels? or maybe spacers?

A width of 275 is too narrow for me, and i prefer 295 (maybe 285). I don't think I install it on the current 20" AMG wheel i have. What do you think?​​​​​​​

 

I think the difference between 275 and 295 is about 3/4". You'll be the only one to notice an extra 3/8" hanging out past your fenders, and you won't be able to see it from the driver's seat. So why risk tire rub for this insignificance?

 

I put G63 wheels on my G550, the 22" Forged version, and had zero issues.

 

oh really! I'm trying to get a better stance, but not too aggressive. Was thinking of putting a 295 (or a little wider). Maybe put a wider fender, perhaps a G63 fender.​​​​​​​

 

that's great. I think the G500 and G63 have an identical space/clearance in the well. What tire size did you install?
