C63 - Widest 19" tires that fit the car (if I buy the right wheels)?
I've been looking around to find out but did not find my answer and I lack the in depth knowledge to make this determination on my own.
I drive a 2011 C63 with the stock 18's with 235/40R18's up front and 255/35R18's in back.
I'm considering buying 19" wheels in the spring and I figured I might as well consider widening the tires at the same time.
My question is: what is the widest tire I can fit in front and in back on the C63 on 19's, given that I would buy the appropriate wheels to match (width and offset or spacers), without having any rubbing or fitment problems ?
Notes: my suspension is stock and will stay that way. I rarely drive with more than 1 passenger up front and my 3yo in the back.
Thank you all for your comments and feel free to point me to a thread or site that I may have missed that covers this subject...

Ya they rub the inner plastic fender front and rear. SLIGHTLY. About the size of 2 quarters. Nothing to worry about, but I wouldnt go any bigger.
If you are worried about traction. Getting a softer tire will work better. Something in the 200 tread wear range will hook up good on the street, but they won't last for long.
I run 320 TW on the rear, they spin but last a hell of a lot longer. I use a 275TW on the front.
And its 245 for the front, NOT 255 like I had.. I went and checked.. Check out Nexen N3000 for the rear. Deep treads and they are harder so they last long compared to most. Did I mention they are only 250bucks a tire too

I would like to get as much performance as possible while staying safe in regard to rubbing. My car is essentially stock and with no lowering. Any thoughts?




New wheels and tyres have aesthetic appeal but the unseen LSD will give your more grip.




Looking in to purchasing 2013 C63 coupe and will get LSD eventually probably form Speedriven. But meanwhile because it will be a DD i would like to be as safe around the corners as possible. The car has allot of power and i would like to get best traction i can so i don't slide out every corner. Now don't get me wrong, im not planning on stomping the gas pedal every corner but there is allot of torque and based on what i keep reading im getting this idea that the car has so little traction that its like driving on wet road all the time.
I'm thinking i will get a nice set of 18s and want to know if 285 will fit in the back in Conti DWS 06 or Mich PSS.

I used to have 275 on my S550 and that was plenty but car was heavy and only 400 torque. On 63 i'm afraid it will feel like i'm on ice all the time.

I will absolutely get LSD just not right away.

I'll talk to Speedriven as soon as i can.












For what it's worth, my 19" 275 MPSS fit in the back without rubbing at stock suspension height.
Also my 285 Nitto drag radials fit fine on the stock 18" rims, also without rubbing
Or more accurately, when the difference between two rear wheel's rotational speed is greater than a certain factor/percentage.
Good to know that they work on this monster as well.
