i ran et 33 with a thick 235. about 6mm of clearance.
he may need a 2mm spacer to clear.
235/40/19 would be a better square setup probably if thats what he would want but you would be burning the rears for days.
I was asking about an 18" wheel setup. Not necessarily looking for a square setup. For some reason tire rack only shows 18x8 +35 as an option for both front and rear for the BBS SX wheels.
i literally rubbed the shoulder off at 19x8 et30 w/ a 245
cannot recommend that - or guarantee that it would work
did you have a c43 before?
I am running the oem 19" forged wheels from c63 w205 with 235/40/19. `19x8.5j et33. it very very very lightly scrubs. until the part that rubs is gone then its fine. et32 is prime for me. this would be similiar to a 19x8 et38. so i think the clearance may be 1mm but it would be tight. there is also tolerance from car to car. i may have a wider tolerance by 1mm too.

alignment and tire brand would impact it's so close. so yeah - still can't recommend it.
OP, go to BBS website direct and find a distributor. they make a 9" wide wheel for the rear to make a staggered set up. tire rack isnt a great place to go for our car, they only sell what they know will fit with tons of margin. nothing wrong with a square setup though if you want it. I just think the rear tire will be smokin more frequently due to less traction.

I've checked the application guide (attached) for the BBS SX wheels and these are the options i'm seeing for W205 fitment:
18x8 et35
18x8 et44
19x8.5 et32
19x8.5 et46
CarID.com shows the other offset options, but they are out of stock.
Looking to possibly purchase a set of Vossen HF1s for my C450. I am lowered on HR sport springs and was wondering if the following would fit or would I have potential rub or interference?
Front:
19x8.5 ET30 with Hankook Ventus K12 245/40/19
Rear:
19x9.5 ET45 with Hakook Ventus K12 275/35/19

step down a tire size (sidewall too tall) - you might have issues with rubbing through your fender liners. if you want a meaty sidewall you're better off with 19x8 and 19x9
Anyone know a good all-season tire that would fit on 19x8.5 et35 in the front and 19x9.5 et45 for the rear? I was hoping I would be able to run 235/40/19 for the front and 265/35/19 but this has been a little bit difficult to find.
Hi all, I have a stock ride height 16' c450. Was looking to upgrade tire size to get more cornering performance, also important for me is to avoid rub. I'd like to keep as close to the stock width difference as possible, i.e. 20mm front to rear (stock 225 front 245 rear) whereas not to affect to cornering balance. As mentioned above these cars tend to understeer and I dont want to exacerbate that. I have some general questions. I'd like to run a 245/40 up front and either a 265/35 or 275/35 rear (summer performance rubber). Does anybody know the front/rear rolling diameters for the stock 450 wheels and tires? Are the rolling diameters on the sizes I listed appropriate for a c450? I'd be looking to pick up a set of 19x8.5 front and 19x9.5 rear wheels to mount them on. I have read this entire thread start to finish and I clearly have a very poor understanding of offset, so some direction would be appreciated. What range of offsets could be ran on a c450 with no rub issues. Also, does anybody have recommendations on tire sizes to avoid because of pricing/availability? I dont necessarily want a list of wheels that fit but instead would prefer a set of parameters that would work on the 450 without fitment issues. Any help would really be appreciated. Also, if anyone knows of a good resource on the subject of offset, I'd be interested in reading that so someone doesnt have to spend their time explaining.
Thanks for creating this thread everyone, still have some questions, but learned a lot already.

I find this website tool very useful for calculating tire dimensions.
with regards to offset, just google wheel offset explanation. It should bring up tons of websites that would give you a general understanding of positive/negative offsets. What it means the higher or lower the number is for offset and whether it sticks out of the body of the fender or not.
Generally, if you’re stock height and go for 19x8.5” width, the front offset range would be +30 - +28. With a 245/40 19 tire, don’t be surprised if you see the clearance from the tire to the suspension arm nervously close... It is what it is, if you wanna go 8.5” width. The rears are more flexible, so that really depends on your taste on how flush you want it to be. Anywhere from +45 - +50, depending on your rear width.
Happy wheel hunting!

Thanks for the info. Would adding spacers on the front eliminate some of that close proximity to the suspension geometry? Also, would it be so close that it may rub at full lock (depending on tire choice)? As far as I understand spacers effectively change wheel offset. Im going to do some research now so maybe I'll find answers to some of those questions. Thanks again.
Edit: That calculator is a great resource, thanks. Seems like a 245/35 and a 275/30 is the way to go without changing factory width difference too much. I also see that a 245 tire can fit on an 8" rim. Maybe that is a better option

Finally got the chance to post some pics. Just got the custom TSW Mallory’s on with some Pilot 4S’s. With the H&R springs fills the wheel wells much better, than the stock AMG 18”s.
Decided to custom hydrographic them in carbon fiber with custom tinted MB center caps
Wheels: TSW Mallory: No spacers needed
Front: 19x8 eta 32
Rear: 19x9.5 eta 53
Tires: Pilot Sport 4S
Front: 235/40 R19
Rear: 265/35 R19
Hope this helps those who are searching; like I did when I was reading this thread. Next up still waiting on my CF hood.
Now just waiting for my custom carbon fiber hood to come in then turbo install.
go w/ 235/40/19 and 265/35/19 w/ small spacer for the rear
Hmm ok, tbh my main goal in upsizing rim size to 19" (I am on the stock amg 5 spoke 18") was to get more rim width (and with that a wider tire). If it's only really reasonable to fit a 235 I may just cram that onto the stock 18x7.5 rim and go up to maybe a 255 in the rear.
Looked into things a bit more as well, the stock front rim is 18x7.5 et 33, and the wheel I was looking at is a 19x8.5 et 32, meaning I'd be shoving another inch (24mm after accounting for the 1mm loss in offset) of wheel toward the front suspension. That's before accounting for a 20mm gain in tire width (I'd assume 10mm of that would be toward the inside), and the fact that summer tires are wider for the same width measurement than the all seasons that I have stock. With that being said, it seems like I'd be losing about 35mm (maybe a drop more) of inner clearance. In the morning I'm going to check inner clearance at full lock in both directions, and at a few other angles. Will report back on that.
Alexasa I see your post above about you scrubbing the inside with a 19x8 et 30, with those specs and the same math I did for my situation, I calculate you lost about 19mm inner clearance.
Also in regards to post by star4life, reporting 19x8.5 et 33 with a 235 tire, I calculate inner loss of 30mm. Star4life reports very very light scrubbing.
Seems to me like this can vary from car to car, rim to rim, and tire to tire. I'd love to be able to step up to a 245/275 setup, would any combination of front and rear spacers make this do able? I'm stock ride height btw.
Thanks for all the knowledge everyone.

diameter doesn't go well with 245/275
cramming wider tires on narrow rims doesn't help achieve anything productive either. fit tires meant for the width of the wheel.
