C450/C43 Wheel Fitment Guide
Perfect if you ask me. See attached. BTW, I even run 265 for winters in the rear without problem. (I had a set
from a previous vehicle so that's why I use them).
unless you're tuned.
I´ve been looking for rims that will surely fit, but it´s a jungle out there. Have tried to read most in this thread, but maybe not all. So, I had my C43 coupe at the local wheel dealer here in south Sweden and measured clearance with OEM 19" wheels. At rear its no probs both in and outside, could probably swallow 10" wide rims. But the front clearance with the very narrow OEM 7,5" is just 15mm inner from suspension strut and 11mm outside before sticking outside the fender. Means if you go up to 8,5" in front, they will stick out even with minimum clearance inside. I don´t want that. 8" is the most narrow aftermarket I can find, and it will be with ET30-35. My dealer found a very useful site to calculate how your new setup affects inwards and poke out: www.willtheyfit.com

Im currently running Michelin AS3+ stock sizes (225/40R19 & 255/35R19), My plan was to size up to 235/40 and 265/35, but unfortunately Michelin doesn't make the AS3+ in the 235/40 size. My options are to switch to different brand/model tires (which I do not want to do), Stick with the stock tire sizes or upsize to 245/35R19 and 275/30R19 (if it will fit), If I size up in width, I would have to size down is ratio, would this effect drivability?.Also which set up would look more visually appealing and are there any benefits/drawbacks from either tire set up? Thanks in advance gang.

Going to be running 225/40/19 & 265/35/19. Will these fit without spacers at the front because of the +3 offset that the wheels? Currently on stock height and have no plans to lower it.
There are sets of wheels out there for the cost of one OEM replacement.

I'm open to running spacers, would prefer not to. Thanks for the help!
went with cheaper rims as I will be returning car after lease...I will just sell them before return and the amg 18" oem will serve as my winters. They are 20" ...rears are 10" wide...fronts are 8.5" with 5 mm spacer. I was gonna go black but happy with the chrome..more pop...CHEERS
