Hey guys, new to the MBenz scene, just got my 2012 c200 sedan, and first thing is getting new wheels on it!

I'm looking at getting myself some Vossen CV-3's in 19" but am confused about offsets. I've had a look at this on eBay

http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=261614751318&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en
The seller has
Front - 19 x 8.5 ET45
Rear - 19 x 9.5 ET35 - Deep Concave
Rear - 19 x 10 ET38 - Massive Concave

will any of these setups fit my car? Or is there something else you would recommend? Definitely set on this type of wheel and I don't plan on touching the height of it. Just want the widest/most aggressive look I can get without touching the fenders/guards or messing with anything. recommendation on tires and or offsets?

The fronts will be fine. The rears, however, it's so on the edge it's a close call. I'm going to say it's a bit over spec. You should be able the run a 255/30/19 on the rear but you will most definitely have to roll the rear quarter fenders. I'm on a 9.5 + 38 and I rub occasionally, although very minimal.

19x9 et39 all around. Rotiform SNA. For Sale too

my rears are 9.5 ET35. Although they are only 18s, I am running a higher sidewall with no rubbing. Rear tyre spec is 235/45R18

tejgambhir

Thanks for the reply! Yes the rears is what I had an issue with. If I wanted to go 19x9.5 on the back, what would be the best offset to go, which would get me the widest tires on the rear without any issues, just bolt on?

Just installed the wheels. Rubbing like crazy in the front, I can hear the tires rubbing the inner fender liner just lightly cruising around the block. Then can smell burning lol.

I suppose the tire is way too tall for the fronts, going to need to swap out the fronts.

I'd also try to get a tire that gets as close to OEM overall diamter as possible. Not sure if you have a 4MATIC but when I get my new setup I'm concerned with what differences from OEM spec diameters will have on the AWD drive train. Tire sizes I'm looking at for vey similar wheel specs as yours and 04boxster all have a +-1% difference from OEM spec.

Does anyone know how differences in diameter make on 4MATICS?

jahnadrian

I just went ahead and got some 225/35R19 just to avoid any rubbing.

When I use an online tire calculator to check the difference between the rolling diameters of:

Front (225/35R19)
Rear (255/35R19)

I get a difference of 3.2% for rolling diameter between tires up front as opposed to back.



Interesting enough when I put the stock tire sizes into the calculator there is a 1.2% difference between rolling diameter between the fronts and backs.

Stock sizes:


225/45R17 F
245/40R17 R


Considering this, this means my rolling diameter is off by 2% from stock. This still worries me especially since I'm 4MATIC.

phenom3030

The way I was concerned was inputting OEM front specs compared to new front wheels i.e.

OEM front: 225/45/17
New front: 225/35/19
= .9% difference

OEM rear: 245/40/17
New rear: 245/30/19 (Not sure if they make this size though)
= .3% difference

I wasn't as much concerned as the difference between front/back since that was the way MB intended. I just want to make sure whatever new set up I put on is near what OEM spec is.

I would like to know if 19 X 8.5 with +38 offset in the front and 19x 9.5 +40 in the rear will fit my C300 without any alterations or adjustments? If so what size tires should I get to ensure no rubbing or rolling of the fenders? I don't won't the rims to protrude beyond the tire.

Does anybody know how far these rims would stick out beyond the fender? I came up with 1/2".

I'm looking to get the KOKO KOTURE WHEELS MATTER BLACK

Thanks in advance I definitely appreciate the feedback

04boxster

I run near the same setup except +35 In the front and I have 225/30/19 and 255/30/19s and have virtually no rub in the rear lowered on H&R SS. The fronts don't rub at all! You are clear for takeoff sir!

Btw my setup does protrude slightly. You'd have to run 235/35/19 and 265/30/19. Your offsets would be fine on a w203 but since its a w204 you'd probably have to go up a few points front and rear without fender mods if you plan on lowering, it's on the cusp.

04boxster

Just use this for reference, I run the 19x9.5" +40 in the rear on a "skinny" 255/30/19 lowered on H&R SS and occasionally slightly rub when the car is loaded. You want to make sure the tires run skinny, there's a thread somewhere on this that shows what tire brands/models to buy to achieve this. For instance, I had 235/35/19's on a 19x10" on my old E46 but they were falken fk452's and they seemed wider than my Acellera phi's on my w204 that are 255/30/19. I think this is most overlooked part of fitment. Tirestretch.com I think is where I researched this. Made a HUGE difference!

04boxster

I would have ran a 265/30/19 in the rear. The 255/35/19 will have a taller sidewall and contrary to popular belief will not have the fender tolerances the 265/30 will give you. Also the rears will look slightly taller in perspective to the front, the most congruent sizes for the rear again will be 265/30. Good luck, however, and I didn't review your offsets but depending on how aggressive they are you still may be in good shape.

04boxster

The 245/30/19 does exist but very rare and only a few models to select. This makes them very expensive and a quick replacement does not exist. I have 255/30's and even those can be tough to source quickly but the difference is shocking in terms of availability. Overseas these tires seem to be much more readily available.

Hey all, looking at getting a slight spacer for my rears. They're 19x9.5 +52 (Niche Targa) with 255/30. It's a 08 C350 sport sedan. I'm thinking maybe a 5mm or 10mm but I think a 10 is pushing it. Any specific brands I should look at or certain types of spacers? Kind of a noob to spacers. Thanks!

04boxster

You'll be fine with a 10mm with that setup. http://www.hrsprings.com/products/trak/

TheUniballer

Cool thank you! Which of those would be best? It sounds like these:

DRA Series spacers bolt to the hub with special wheel bolts (included) and provide new threaded holes for the existing wheel bolts.

But I've never ran spacers on any of my cars before, and this is my first German.

The other two are as follows:

DRS Series spacers fit between the wheel and hub, and require exchanging the existing wheel studs for longer ones (studs are included).

DR Series spacers fit between the wheel and hub, and require longer wheel bolts (ordered separately). Please verify bolt specifics before ordering (taper or round bolt head and shaft length).

04boxster

I've honestley only ran spacers one time to clear front brakes on a w203 and they were slide on spacers. I would contact H&R or seek real world application advice from someone that's actuall ran them. I know there are advantages to both. I hunch tells me a 10mm+ would probably need to be a bit more substantial to avoid rotational vibration.

TheUniballer

So if I were to get a 10mm spacer and 40mm lug bolts, would that work? From what I've found oem lug bolts are 27mm(ish) so would a 40mm work? I cannot find conical seat 37mm lug bolts.

xjaymzzx

niche targa is extremely heavy , i know their 18s are like 35 pounds so you're going to lose speed. and also aren't they cast wheels? i would choose a lighter weight rotery forged(at the minimum) wheels.

xjaymzzx

i wouldn't use a wheel spacer unless i absolutely have to. Do it right and go for a wider rim with a correct offset. Wheel spacers puts more stress on the wheel bearing, so i've heard.

TheUniballer

Well it's not a race car, I drive it every day to work, so the weight isn't really a big deal to me Purely for style/looks. Wasn't really sure of the fitment either, so I didn't want to get a lower offset coupled with a wider wheel, when I could just get spacers and get what I want that way. Seems like a smarter way to do it than just go and buy wider/lower and have no way to make them less aggressive. then what do you do?

xjaymzzx

You also loose fuel economy and brake distance, it's your daily driver. And how bout making sure the correct size you want before buying and then fixing it with wheel spacers? Increasing the chance for something to go wrong or cause vibration of your steering wheel? how bout doing your research and do it correctly instead of ghetto rigging it. Wheel spacers should be a last resort

Reading your posts, you clearly did not do any research.
Let me ask you a question, how are the quality of the roads you drive on? Riddled with potholes or smooth?
If it's smooth you can probably get away with 19 inch cast wheels with **** load of wheel spacers. Otherwise good luck with crack and/or bent rims.

Also if your worried about rubbing, do your tire research (ie some brands like Michelin runs wide) 1/2 inch wider then other brands of the SAME size.

xjaymzzx

I went very conservative with offset and width and I got the perfect fitment I wanted.

TheUniballer

If I wanted MPGs, I'd have bought a four cylinder. Plus I doubt a 38lb wheel is just destroying my mileage/braking distance. I get the exact same mileage on each tank as I did before the wheels. Wheels will get bent/cracked if you don't pay attention while driving to ensure you don't hit things, regardless if they are forged or not. I also have Toyo tires and am not worried about rubbing whatsoever.

I did do research, just not here. I'm sorry I didn't want to spring for custom offset. I contacted Niche, told them what I drove, they had already had these wheels on W204 and said a great fitment that isn't too aggressive or too sunk is what I have. I'd say that's about the best source for research you can get. I asked them about a bit lower offset and they said it will increase the price for the rears and will have to custom make the wheels. They then told me if I want a little better fitment, to see how I like their width/offset and TO ADD SPACERS if I wanted slightly more aggressive. Also, 10mm is far from a **** load of wheel spacing. 10mm is less than a half inch, and wouldn't getting wider/lower offset be the exact same concept, putting the exact same stress on the hubs? Better safe than too much poke and looking like an idiot with wheels that don't fit. You act as if I bought 19x7 +100 offset and am trying to fix it with a five inch spacer or something stupid. I really don't understand your hatred of TEN MILLIMETERS. :

I'd be delighted to know what your specs are btw.
