I can gauge from previous posts that it seems like a 10.5 inch wide may fit the E 550 coupe. Even if I clear suspension components my 3 MM ..LOL.



Asking for professional feedback..can the following fit? ( I can CNC “shave” the rim backpad if the wheel needs to be “tucked in” in order for it not to pop out).

WITH A 305/30 19 TIRE?



Im going with a very aggressive 700+ lb of torque tune (with bigger intake manifold, high flow primary cats, 2nd cat delete) and want to get giant steam rollers at the back.



I’ll do inner fender modifications if necessary, so long as the body structure or suspension structure is not compromised.

 

I just did the Renntech tune on my E550 and it provides 705tq, right at 600 to the rear wheels. I am running 19"x9.5" C63S AMG wheels in the rear with Michelin PS4S 275/30R19 and they handle the torque just fine, honestly better than I had anticipated. 1st gear is iffy, but 2nd gear on up in a straight line has good traction on most (dry) surfaces. The car could really use an LSD to put the power down better in low speed turns.

Hope this helps!

 

wanted to fit the c63 COUPE rear wheels since they are wider and have that concave look.

looking to leave nothing on the table in terms of traction /width.

 

I understand. I wanted the absolute largest wheel/tire combo as well because I knew I was going to do the Renntech tune. I wanted to stick with factory rims and unfortunately, from the research that I did on this site and several others, those coupe wheels will not fit a C207, especially with a 305. I learned that the C63S 19" wheels fit perfectly with no spacers, and they are very close to suspension components. I believe that I could have fit 255/285's, with a slight chance of rubbing, but those sizes only came in Pilot Super Sports and I wanted Pilot Sport 4S, so the 245/275 combo was the largest that would fit. I have no rubbing issues whatsoever, and no regrets.

If you manage to fit a 305 without clearance issues, please be sure to tell everyone here how you did it because I believe that you will be the first that was able to manage it. Best of luck to you!

 

Member: crazy00c230k Has ET 50 19x10.5 ‘s and a 265 tire (it looks stretched so I can see fitting a 305 on there).



He says he says hes lowered and no rubbing or issues. Looks good ! and it doesn’t poke out, just sites super flush with the fender.



Think of the new shelby GT500 look (in terms of rear rim and tire fitment and that’s what his prob looks like.

 

Does anyone know if these s63 amg wheels will fit a 2012 e550 coupe?

rim size: 8.5 J x 19 ET 38
rim size: 9.5 J x 19 ET 38

Yup! I'm actually running a 275/35 with no issues at the moment, was on a 285/30 before lowering, fender clearance became an issue at my current height with the 285s though. With the 275 there is only around a half inch clearance between the strut and tire. I think going 305 would be cutting it real close (an extra 15mm/0.6in on both the inside and outside of the tire). Some pics below for your reference.

 

thanks for chiming in.

im trying to fit the w205 c63 coupe wheels to the rear.

when you went 285 was it rubbing on the inside fender lip? or the fender liner or both?

do you think modifications to inner lip or liner would do the trick

i dont want to do 275's cuz then i might as well go with the sedan wheels.
even if i can push 295's with a low aspect ratio.

would going with a KW v3 afford extra Milimeters?

 

I was rubbing pretty badly on the outer fender liner/the plastic that seems to be friction welded on the inside lip of the fender. You could perhaps try to modify the fender a bit, but I've heard they're quite difficult to roll. Not sure if V3s are any thinner than the stock struts, so don't know if they will give you any benefit on the clearance between the wheel/tire and strut. They would certainly help with the rubbing on the fender as you could set the height of the car, I'm at the mercy of how my H&Rs settled. Another couple pics below of the flushness of the tire with the fender. I know it kind of looks like theres a bit of room, but the damn plastic stuff inside of the fender robs you of another quarter inch or so.

 

Your pics gave me an idea and an observation. You said that there is ½ inch between the tire and the rear shock. I checked the part number on the black “tube” in your picture ( thanks for the clear pics! ) and all that thing is, is a black “protective tube” < that’s what’s listed in the parts catalog. That protective tube is wide and thick and is robbing precious inches from the backspacing of a meatier tire.



It “protects” the needle like shaft from the environment. Here’s the catch, that can be done away with in order to gain more space as many shock manufactures do away with this “tube”. many kits (Aftermarket and even OEM ) don’t have this, so I am classifying this as a non essential, and non critical part of the suspension setup.



I have attached pictures of a KW kit without it and also a Mercedes parts diagram with it highlighted. If this part were to be taken off, the rear rim backpad can be CNC’d shaved a couple of MILIMETERS, pushing the whole wheel and tire “in” toward the strut, one can gain gain 0.75 of an inch or more space (factoring your original ½ inch). Ive seen hairline like millimeter clearance with suspension components with the mustang guys and although close, there is no rubbing or contact with moving suspension pieces as long as every mm is taken into account.



If the plastic fender well has to be trimmed off completely to gain some vertical clearance there is a method (also see picture of rear plastic fender liner). the underside of the fender well will need to be replaced with truck-Bedliner spray (like rhino), ultra thin dynamat and or weather resistant felt type material (these are tricks used in the car modding industry to squeeze ultra wide wheels in different makes without going widebody or fender flares).



Keep the 305 dream alive!

 

Nice, I'm interested to see how much room removing that sleeve will buy you. Happy modding, keep us updated!

 

Leaving this right here, using the c63 couple Rim specs.



I used a 295/30 19 hypothetical tire size with your wheel specs (19x10.5 ET 50) to gauge difference. It gets pushed in 7mm toward the strut but also (which I guess it’s a god thing) 7mm away from the other problematic area of the inner well/ lip.

 

they will fit perfect tires 235/35/19 265/30/19

 

So did the 305 on 10.5 ever fit? I’m thinking about doing 295 on 10.5 myself. My car peels out in 2nd gear like no tomorrow. And I haven’t even tuned it yet. Also you said you were getting bigger intake manifold. Do you mean the air filter box spacer?

 

on a 2010 E550 coupe, could I put 245/35/19 and 275/30/19?
