Yes, people tend to get hung up on terminology without understanding the principals behind them. With a wheel, and therefore a wheel spacer as well , two things are important, parallelism and concentricity. The faces need to be parallel to one another to stop wobble and they need be aligned on the axis of rotation to avoid eccentricity. A hub-centric wheel centers the wheel on the hub by having a tight fitting bore that interfaces with the axle hub regardless of lugs. Lugs are tapered and theoretically if you install and tighten them correctly should also provide good centration, but with the built in slop the wheel can set itself a little off center as you tighten up.
In the real world, nothing is truly parallel nor concentric. a bore of a cast wheel is not perfectly in the center, the wheel nor the tires are perfectly round, the mounting surface isn't perfectly parallel to the front face. That's one of the reasons we balance. Measuring runout is a good way to describe how true spinning objects are. I don't know actual wheel specs for runout. I would guess a runout of .005" on a 19" or 20" wouldn't be a problem at 100mph which would probably equate to a .001" runout on a wheel spacer. That's precise, good quality, but not super difficult to achieve. As long as the spacers aren't made by monkeys and you install your wheels carefully, should be all good.

My advice based only on my own experience is that a thin 5mm or 3mm hub centric spacer to get brake clearance is no problem. Putting a 10mm or 15mm spacer up front to get a more aggressive stance on your OEM wheels might give you vibration issues and not be worth the trade off.

My wheels will be here tomorrow, so we will see - HRE seems to agree that they will work, I'm not sure if there are others running these wheels yet as previously mentioned as speaking with HRE directly, I've not been given that impression.
With that said, I'm sort of playing the remote "guinea pig". I'm also going with a much more aggressive tire selection that most, so if it all works, then that's going to be pretty helpful.

Yeah, 255/285 is pretty ambitious. I like a wider tire look myself and I'm glad to read you report that a 285 will fit on the rear. I was going to try 245/275 which puts the rolling diameters closer than stock as well but is slightly larger than OEM.
Are your wheels/tires coming pre-mounted ready to bolt on, or do you have to take them somewhere for mounting? Looking forward to the verdict.

Believe me after being in this business for 25 years I was not going to set up my car to cheapen the function just to improve the looks. 3mm spacers are typically non hub-centric but are small enough to allow the wheels to still grab the hub. below is a picture of a 5mm spacer that is apart of a hardware kit for a Carlsson wheels, this is a similar system used by Brabus, and also some of the BMW tuners as well. This spacing system is designed with a larger bore wheel that allows the spacer with a hub locking ring to snap into the wheel and the hub bore is then on the side that goes on the car with a 66.56.
Hope this information helps.

285 on a 9.5 rim is going to sit pretty square, in fact might even pinch a little, 285 on a 10.0 will sit with the shoulder of the tire being almost square. This also depends on the brand and tread pattern, but I have heard of 10.5 wide wheels going on the W205 in 20" and using a 295 and getting the clearance, so I will still just only be concerned about that Control arm issue up front.
Look forward to seeing how everything turns out. I am sure many here will appreciate your efforts.

So I poked around my front end last night. With the 7.5" OEM front wheel with a 33 offset, I can't slide my pinky finger between the steering arm and the wheel. Not a super accurate measurement, but it's in the ballpark. Call it 10mm. Wheel spacing calculator puts an 8.5" with a 44 offset 24mm closer to the steering arm and only 2mm to the outside. I see zero possibility of that bolting up. Unless my info about the factory wheel offset is wrong, he will need another 15mm or so of spacer which will probably put the rim lip beyond the top of the fender. Damn, it's almost 5pm in Atlanta isn't it? Where's our report?

I'm thinking it probably didn't work?
I know everyone here is anxious to know, but based on the applications that have already been attempted I think the outcome was probably an equal challenge like the rest.
Hopefully there will be a confirmation. Going forward I think Multi pc wheels are going to be the way to go...more expensive, but at that point they can be built to exact spec to guarantee the fit.

Currently exploring other options with HRE at this time.

I honestly think this car will need to be set up like one of the old AMG W210 applications where you fit a 8.0 front with a ET33-35, and a 9.0 rear with a ET35-38, these sizes in 19 should accept the factory recommended tires with no issues, and allow the tires to sit on the rims with a square position, and fit right to the outside of the fenders.

It would be nice to have HRE reps or engineers chime in. It does look as though they incorrectly lumped their sizing recommendation for the C450 in with the C300 and C400.

Attached is a shot of my car with the 9.5 rear with the factory 255, you can see that the shoulder of the tires are rounded and stretched a little bit.

I know a few of the Forged wheel manufactures that build 1pc forgings in these sizes, and also the multi pc guys as well. The only thing is the cost is going to be a greater expense over the cast manufactured wheels, but it is a get what you pay for deal! Right now there are a few 450 owners that have thrown good money after bad and spent time and money to still be without wheels that fit.

I been looking for aftermarket wheel/tire for the C450. Can someone point me the website or link? I already try tirerack and some other website. Our wheel size and off set is special...Please help

Anyone have info regarding the S205 Estate version of the C450?
Found this article about a company named VATH and they have modified an S205 with 19" wheels with 245 rubber up front. From the looks of the pictures the tires have a bit of stretch so I'm guessing 8.5. Wheels also have some decent concavity to it.
The article mentions aggressive body kit but it looks OEM to me except for the C63 rear diffuser and exhaust tips. Article also mentions upgraded braking but those callipers also look the same.
So does the S205 have a wider front fender than the sedan?

This whole thing blows. My reasoning for going with the 18s was so to throw a set of 19" on for summer and use the 18" for winter. If only I had knwon that 8.5s wouldn't fit.. who would have thought.. I'm probably just going to source a set of W204 multi spokes and run some spacers.

The only concern I would have is with the tires, since running an 8.0 inch wheel up front is going to be required for the suspension, you can avoid doing the guess work with the tires, and so you avoid the rear tires from stretching on a 9.5 or 10.0, which will throw off the OD for the 4 MATIC, I am suggesting to run the wheels in a 8.0 and 9.0 with the 225 and 255 combo.
