So after reading this entire thread.... This is what I've come up with.. combined with using the wheel calculator, as well as my own findings with spacers:
W205 Facelift with 19" twin spoke -- Front 19x7.5 +33, Rear 19x8.5 +52 STOCK
When stock height, you can add H&R 12mm spacers up front and 15mm rear for a more aggressive look without poke. This results in a +21 Front and +37 Rear offset.
When lowered, you can push the spacers to 15mm up front and 20mm rear for an ultra flush look. Going this wide not lowered will protrude beyond the fenders. The resulting offset +18 for the front and +32 in the rear. I THINK I hear some rubbing noises over hard bumps, but I haven't figured out which corner.. Mind you I am slammed on H&R VTF. The car needs to be raised about a half inch or so, all the way around.
Now, I've followed the recommendations in this thread and have ordered wheels 19x8.5 +30 for the front and 19x9.5 +45 in the rear. This actually gives me about the same fitment as my setup with the stock wheels (maybe about a 1mm more poke in the front), just with a wider wheel overall (watch out control arm!)
When looking at tires... the answers in this thread become less obvious, as to what will fit with these wheels.
Stock tires are 225/40/19 Front and 255/35/19 Rear.
Plus 1: 235/40/19 is 1.19% taller than the stock 225 (a bit over 1/8"). For the rear 265/35/19 is 1.05% taller than stock 255. Not a bad combo since this is about 1%.
Plus 2: 245/35/19 is 1.3% smaller than stock 225 in diameter. I originally tried 275 in width.. you either end up with 2% over or 2% under.. 285/30/19 was a better ratio, only being 1.15% smaller, similar to the front in this example.
Plus 3: Only one member has run this wide @mo11 .... 255/35/19 up front. This is only .23% smaller than the stock 225. The matching rear is 295/30/19, also with a .23% diameter difference than stock. The only bad thing here is that this setup seems extremely wide and most likely would rub in the rear (the tire being 1.6" wider overall, so at least .75" more aggressive than stock on each side of the wheel. The way around this was to use a 50 or 55 offset wheel, to give the additional clearance from the fender (sucking the wheels in towards the center of the car).
I believe it is safe to say that my Plus 1 option is the way to go with this without rubbing. I'd love to Plus 3, but I don't think that's a reality.
I'm considering to get Vossen HF3 on Michelin Pilot Sport AS4. Please advise guys.
Front: 19x8.5 (ET30) 235/40
Rear: 19x9.5 (ET45) 265/35
Is this setup any good?
I really need help. I went with same setup but fitment industries recommended I do front 235/40 and rear 265/35. I'm rubbing like crazy especially in comfort mode. Currently, I got Aodhan AFF7's.
Front: 19x8.5(ET35)
Rear: 19x9.5(ET35)
I really want to keep these wider Michelin tires as it feels very nice on the road. Any advice would be appreciated besides rolling the fenders in the rear. I was thinking to get a new set of rims with ET42 in rear, everything else stays the same. Sadly, I'd have to get all 4 as Aodhan AFF7's only come in ET35. Please advise
Any rim recommendations that look nice, lightweight, and rotary forged but not too expensive also appreciated. Preferably silver.
Are you lowered at all? If so what suspension? Are you running spacers at all? If so what size?
I am 100% sure I could have ran that same tire size on my previous setup without rubbing as there was more than enough clearance.
I am not sure as to how you're rubbing with just a slightly wider tire than the oem sizes. OEM FRONT: 225/40/19 OEM REAR: 255/35/19

I'm running 235/40 in front, 265/35 in rear. Rubbing in rear. No suspension mods. No spacers. Planning to lower the car slightly with H&R springs.
Do you think this setup will work and can lower later using H&R springs? Want to get Vossen HF3's double tint black.

Can’t help much but a vendor on here has always gotten me and a buddy to fit perfect

Reason: Forgot
I really don't like how the transmission feels now that I went 235/40 and 265/35. Gears 3-4 feel like they take longer to shift. On 225/40 and 255/35 I was banging through gears like crazy. I think I'll go back to stock sizes 19x7.5 front and 19x8.5 rear. I'm also tuned on Eurocharged. It does feel like car is boosting crazy between gears but 3-4 feels like it hangs up in individual mode, haven't tried sport+ from standstill yet. Grip is crazy.
Please advise if I should keep 235/40 on 8.5 and 265/35 on 9.5 or go back to oem specs, which for amg multispoke was I believe 225/40 7.5 and 255/35 on 8.5. Transmission really doesn't feel like it used to.

I have this exact setup but lowered with H&R springs. That should work before and after you do the springs. Consider running a front tire at 35 instead of 40 if you are definitely going to do a drop. I have some slight rubbing in the front with the 40 sidewalls, but otherwise, it's fine. The rear will look tight, but it's got more than enough space.

@0dte I wanted to keep the same sidewall height, was told different rolling diameter can cause issues with AWD. I believe it's too late to change and I will end up keeping Michelin AS4's 235/40 and 265/35. How bad is the rubbing when lowered in the front 19x8.5(30)? My plastic shields in front are all messed up anyways so don't really care about those, but I do care about my paint and fenders. I could do a 19x8.5(35) as that's what I currently have and when lowered throw a spacer. However, even now it pokes like crazy and I do not like the look on stock suspension, does it really tuck in that much when lowered?
I have not tried a TCU reset. I guess the car just feels different on these wider tires as they're more grippy. Not sure if anybody else here noticed a difference themselves when going wider.
Also, I was in individual mode when 3-4 gear sleeps, maybe cause engine was set to ECO it sleeps and takes a long time to switch the gear when full throttle in that mode or ESP is more sensitive maybe, who knows. Changed the individual mode setting to comfort when customizing it and now it behaves better.
So much info to process. Basically, I have 19x8.5 et32 fronts and 19x9.5 et50 rears. Wheels are Mandrus Estrella matte black. I had the stock run flats (225/40/19s and 255/35/19s)for 3 seasons and now it’s time to replace them with non runflats. Looking at Michelin pilot sports A/S4. I was wondering if I can mount the Michelins with 235/40/19 and 265/35/19 front/rear respectively. I had no issues with the runflat dimensions but they looked pretty stretched. I’m on stock suspension by the way.
I have a 2020 coupe, staggered 19" OEM setup currently, OEM suspension. I want to buy a set of rims that are 19x8.5" ET35 front (will need a 5mm spacer per forum research), and 19x9.5" ET35 rear (should fit without spacer.) I want to keep the OEM tire sizes (255/35/19 rear and 225/40/19 front.) I don't want to lower the car.
Any input if this will work with no contact between the car and tires? Any help is appreciated. My understanding is the coupe has a little more clearance in the back.
I have a bit of an issue, last time I invested time into this thread and learned all this stuff was a while ago and now I forgot and maybe someone can help me quicker than I can learn again myself.
I bought my C43 coupe with 4x8.5J R20 MAM1 GT wheels - all the same size (offset numbers on rims were hard to read, but i think they were ET45).
If I recall correctly, it had 235/35 and 255/30 tyres on them. And all wheels had 10cm spacers.
But then I noticed that all tyres were badly worn on the inside and eventually one had wires out and fully broke down and then I had to buy a new set.
I bought new Vredensteins and it seemed that for 235/35 in the front, wider 265/30 in the back would result in better geometry. So I went with those.
I was worried about the first tyres being worn, but as rims and tyres were cheap, painted horribly etc, I just presumed that seller put on already worn tyres because my R18 winter tyres didn't have any wear on the inside after 2 seasons.
Now after 2 summers with Vredensteins, I noticed extreme wear on the inside of the front tyres.
So now I now I have to get the axle aligned properly, but I also need new front tyres.
It seems that 235 is still quite stretched on those rims. I want to know if I can put wider tyres on it? With 20 inch rims, the wheels already seem very tightly fit in the fenders.
I've seen people put 245's, but I wonder if they work on my rims and offset and spacers.
And if I pick 245s, should it be 245/35 or 245/30?
Or does it even matter at all?
In terms of wear, if 235s are worn already, then with current setup I think 245 would be worse, no?
I also have shock absorbers leaking oil, which might affect the geometry. If I replace those, get axles aligned, maybe the issue is solved and I can get new tyres also 235s?
Sorry for the mega bump, are there other spacers that fit for the front for the same fitment without your modification? I didn't really follow why you landed on 12mm 24556659 front and 12mm 2455665 rear? I'm trying to get some W204 C63 multispoke rims, which are the same size as your setup, F 19x8 et 45 R 19x9 et54. So from your post, the rear is good to go with no spacer, but in order to use 40mm bolts and have one size and set of bolts for both wheels, in addition to putting 12mm spacers on the front, you mirrored it in the rear? I just want to make sure I'm buying the right spacers as I don't have access to a lathe. I obviously don't have your technical knowledge either! But the W204 multispoke rims is the closest rim to give that CLK black series 16 spoke look. I'm not lowered and am looking for conservative and problem free fitment. Thanks again for all your research, incredible gift to the community.

So final specs are:
Front:
235/40/ZR19 Michelin Pilot Sport 4s on W204 OEM Forged C63 Black Series wheels 19x8 et 45 with a 12mm 24556659 spacer modified per above lathe pics.
Rear:
265/35/ZR19 Michelin Pilot Sport 4s on W204 OEM Forged C63 Black Series wheels 19x9 et54 with a 12mm 2455665 spacer.
dude thank you so much, I think i'm a bit lower than you so getting 4mm more with that stretch should be perfect. I think I'm going to pull the trigger on the Vertini RFS1.3 flow forged in silver on my car here
What suspension set up were you running here? Also, what model wheels are these? OEM? Thanks in advance!!
Hi all,
Does everyone has any feedback on using spacers and impact on the car for driving and long term maintenance?
I was initially going to get new wheels but I actually quite like the OEM ones, it's just that at the back especially the wheels are way too much tucked in and I would like to address that.
Thanks
Looking for hp finding aftermarket wheels for my 2017 C43 AMG. Currently running factory tire size front 225/40/19 and rear 255/35/19 with TSW Mandrus Arrow matte black rims (I "think they are front 19 x 8.5 and rear 19 x 9 but I'm not certain - don't know offset, hub and lug thread info).
I'm having trouble verifying the offset range, hub bore and lug thread size(s) and finding rims that will work. I'm willing to replace the tires if needed, but they have ample tread.
I live in a remote area, therefore want to ensure the local installer knows exactly what to do at install since I've already had to return an order due to non-fitment (went through a aftermarket rim tire retailer).
I am just a C43 driver - I have no affiliation with any seller.
I bent my OEM 19" wheels 3 times in the first year of ownership. I went through the same thing- trying to find wheels for my C43 Coupe. The C43 has a hard-to-find offset and lug pattern. Wheel Designers actually stocks blank wheels and they machine the offset, bore, and lug pattern to fit your vehicle. I ordered a set of wheels from them back in April and they have been great. Perfect fitment and no adapters needed. I did 19x8.5+32 front and 19x9.5+45 rear on OEM size tires, SF03, gloss black tinted face.
Got mine from wheel designers, a vendor on here, James took care of everything. Shipped my wheels so all I needed to do was mount tires and direct swap from stocK.
After having my 2016 Mercedes C450 AMG for nearly 10 years, I finally replaced all my wheels after having two very expensive AMG front wheels crack on me. This forum thread helped tremendously in making me decide on the right size wheels and tires to get. My goal was to have the least wheel well gap as possible and to have tires as flush to the fenders as possible. I wanted to keep the 19" diameter but widen both wheels and tires for better grip and handling. I used all the notes from the messages found here and calculated the different settings using an online wheel and tire sizer (https://www.wheel-size.com/) to analyze the best fit. I decided to go with Niche Misano staggered wheels with 19"x8.5" 34mm offset fronts and 19"x9.5" 50mm offset rears since I like the look of split spoke wheels commonly found on Porsches. I also decided on Michelin Pilot Sport 4 S (PS4S) tires with 235/40R19 fronts and 265/35R19 rears. I believe that Michelins perform better are more square at the corners than rounded Continental tires. Going with 20" wheels and wider lower profile tires would have looked nicer but I prefer comfort and performance over esthetics. Had I just went with the wheel and tire recommendations from companies like Fitment Industries or America's Tire, it would have been far from ideal. Using the website online wheel recommendations, it said I had to get a 25mm offset for fronts and 35mm offsets for rears which didn't make much sense since the offsets for the stock AMG wheels are 33mm for fronts and 52mm for rears. Based on my research, I concluded that 28mm offsets for the fronts and 38mm offsets for the rears were the maximum offsets one should use when using wider rims and tires on 19" wheels for a C450/C43 AMG. To come close to those ideal offsets, I used a 5mm wheel spacers on the front (34mm-5mm=29mm) and 12mm spacers on the rear (50mm-12mm=38mm). After using a leveling ruler to check how flush the wheels were to the fender, it showed both front/rear wheels being flush with fenders down to the middle of the sidewalls which means there should be plenty of clearance from top half of sidewall to the fender to avoid scrubbing. There should be more fender clearance once car is lowered in the future due to slight negative camber. See end results from pictures below (sorry for a dirty car, lol) and let me know what you think.
