Hey guys, waiting on my car to come in, super excited about getting to snag the perfect c63s! One thing that bugs me about the car, before I even have the car, is the wheel/tire sizes. From what I read the car runs 19s stock, 265/30 in rear? Not a fan of the 19 size and really wanting to step down to a 18" and run a drag radial.

1) how wide are people going? Would 10.5 be too much? I'd keep the offsets high like they come stock (+~50 ish?) would 9.5 be too wide for the front? Definitely not trying to pull or roll (maybe roll) just yet....

2) 275/40 or even wider, would it fit? How much room do the stock setup leave you to play with?

Anyone else done this? Any pics or info would be great. Thanks in advanced.

First biggest question is are you getting a coupe of a Sedan? Coupes can run 11 in the rear sedan cannot.
As far as 18s the s model will NOT fit 18s in the front due to the enormous rotors. I am not positive but even the rear the way the calipers are positioned 18s may not fit in the rear either.

People have gone up to 295 in the rear on the stock wheels.

I am now running 285/30/20 and 255/30/20 on 9.5 and 10.5 inch wheels.

Ok awesome info, didn't think about this things massive brakes!

I'm getting a sedan, 11s would have been awesome 😭

So I guess to avoid crazy 19 tire prices I go up to a 20 rather than 18? I wish i could run more profile, 30 is soooo thin..

I have a sedan running 18's currently am 245/40 front and 265/40 rear...if i wish to go wider by 10 mm front and rear can I still run a 40 profile or will i have to go (255/275)/35?
