C63 AMG Wheel Fitment
The wheels im running right now on the Front 19x8.5 42mm are 225/35ZR19. Rears are 20x10 38mm 285/25ZR20 and those are the ones rubbing and hitting the fender hard.
Also, what about a 20x9 +38? Few places said 20x9 would clear the fender/breaks without having to roll the fender.

Even with a 45 offset rear you would need to run a 255 tire to "maybe" clear the outer fender so no gain in rubber on ground.
With option 2 above you can run 245/35x19 on front and 275/30x19 on rear, No Rubbing.




You might get away with a 8" x 38mm offset on the rear but no way a 9 or 10" wheel.
Good luck.

Hope you can get them to work with you on this, I'm in the boat of getting new wheels and honestly I'm over it, I can see why you went and trusted a shop but there is so much contradicting information for what fits these w204's it's not even funny.
Not to mention that "wheel Thread" is such a waste of time with no one putting ET's in and all. It's like ok you can run 19x9.5 but what offset, spacer needed who knows but look at that pic lmfao.

So if you’re running any Michelin/Pirelli/Continental tires do +50 offset on the rear otherwise, do +48 offset.




+48 might give you a more flush fit but if you choose a tire that is a little wider than the rest it may rub then your back to square 1.




Try and get your head around this. "20x10 +38 285/25ZR20" . WILL NOT FIT. on a W204 C63 chassis.
Btw the W204 c63 does not have air suspension.

As a baseline, I run 19x10” rear wheels with a +52 offset and they’re perfect.
(you’ll find that your questioned offset may work, but you’re wasting a ton of room)

my question other question is... will I be good with the 20x9 +38... I know I’ll b fine and not hit the fender... will it be flush? Will I destroy my wheel well daily driving? I’m not tracking the car, but, I do like pushing the car... instead of the digs, I need help... I’m not trying to be a bother with this whole thing, I don’t know much about cars but I’m trying to learn it... this is a 2100 mistake... cheaper if I drop to the 20x9s




If you plug into the calc a spec like mine which is dead flush, and your proposed offset, you will see that it extends 1mm further out but you’ll have 27mm extra space to the strut. Not ideal but it’s your car man.
