So I'm about to pull the trigger on some wheels and am unsure/want confirmation that they will fit; I never trust the sales people anywhere since they don't know anything about any specific car. I've also consulted the Mercedes wheel fitment chart, but it only has fitments for 9's and 10's--no 9.5's.

What I'm planning on getting:
Front
8.5"; comes in 25mm or 35mm offsets

I'm thinking either one would fit with no problem, but will probably go with 25.

Rear
9.5"; comes in 28mm, 38mm, 42mm, or 44mm

I'm thinking 28 is the only one that will fit here.



What offset ranges will fit (with or without spacers--please specify)?

I would like to go with this wider staggered set, but will settle with 8.5", 35mm all around as well if the 9.5's won't fit.

7.5 32-35 front 8inch front 38 ,,,,,rear 8.5 32-35 rear 9-9.5 31-35

I think your numbers for the 8.5 are off a little, as stock offset for the 8.5 in the rear is 30.

And I'm definitely not going below 8.5" in the front.

Do you think I can push 28 in the rear for 9.5?

Outlawlatemodel

actually i sell wheels 28 is pushing it

importfan21

Ah, well you're the perfect guy to ask then!

According to the Mercedes fitment chart, it says 9's would be ok with 28 or 35 (Carlsson) and 10's would be ok with 25, 27, 30 (also Carlsson). Obviously 9.5 is between the two, so I'd imagine it would be fine.

What would be any potential problems?

All your suggested wheels are critical...

8.5 with offset 25 is critical at the fenders and with steering, offset 35 will be critical at the inside of the wheel (will depend on tire). Offset 30-32 should be best...

The 9.5 should work with the offset 28, but maybe some adaption will be necessary (rear bumper), all other offsets are too high.

You never know if it will fit before you did not test because the tolerance of the car and tires is too much.

Alright, so either 25 or 35mm for the 8.5 front---both seem to possibly cause issues.

On second thought, I may just stick with 8.5's in the rear too and go non-staggered. If that's the case, I'll run 35mm. If I stick with 9.5, looks like I'll go 28.

Anybody else have thoughts? 503C43///AMG, where are you? I know you have wide wheels; need your input.

503C43 ////AMG

My rims are stock off sets (I would suggest you stay as close to stock as possible to avoid problems)

I have 8.5 in the front and have an offset of 31
I have 9.5 in the rear and have an offset of 35

I have 235/35/19 tires in the front
I have 265/30/19 tires in the rear

I will admit the fronts are SUPER close on the inside AND the outside (especially the inside!)

BUT....

NO RUB!!!

importfan21

"Super close" as in how many mm? Think I can get away with 35? And that's with running your Vogtlands, correct? How much of a drop?

503C43 ////AMG

Vogtlands with 1.4" drop (have #5 pads in the front and #4 pads in the rear so it was supposed to be less than a 1.4" drop.)

Super close = I don't think you can get away with 35, stick with the stock offsets or as close as possible. My tire is literally a piece of paper away from touching the control arm

importfan21

Damn it. All the 8.5 wheels I find are 35mm or higher, with the exception of one with 25mm. Stock is 35 (but with 7.5 wheel).

I have H&R sports (not installed yet), but should give an estimated 1.5" drop. Thought I'd ask for your drop, regarding (lack there-of) rubbing issues.

Edit: Also is it more of the tire being close to the control arm, or the actual wheel? I'm thinking of running 225 on the 8.5 in the front.

Outlawlatemodel

on the front it is actually the front spacing the problem, on my 43 if the wheel had less offset it would rub the lip unless i put more camber in it, why 8.5 on the front and 8 inch with 35 would be best, if you want to go 8s all the way around you could put a one inch spacer on the back to fill the wheel well

503C43 ////AMG

Its both the tire and the wheel that are that close to the control arm.

Check out Mandrus wheels, they are made for our cars and have the correct offset.

running 225 on the front may get you further away from the wheel well on the outside but will not affect the distance on the inside next to the control arm

importfan21

Yeah, I'm looking at going 8 (at least in the front) with 35; downside is, that size/offset combination is only available on a 17in rim (same version of the wheel originally posted). So I could go 17x8 front, 18x8.5 in the back, but that would look a bit off.

I could go 17x8 all around and run spacers in the back. Didn't think about that.

I'm pretty dead set on the wheels in the original post; I'm real picky and the ones I like either don't fit or are questionable. No Mandrus for me. So basically it's the wheels in the OP or I'm sticking with my monos.

did you end up getting the 8.5" with 35 offset wheels?

im in a similar predicament as you were

the only thing im gonna try is just taking the stock C43 rear wheel and putting it on the front to check clearance, the 8.5" wheel with 35mm offset will only extend 5mm additional to the inside than the stock rear wheel, so i should be alble to get an idea of how much room is there when i do that. (if that makes sense!)

seems as if the rear wheels are not really an issue.

17x8 ET35 front; 18x8.5 ET30 rear

I use this website to check if the offset will fit http://www.rimsntires.com/specs.jsp

Dziner82

thanks for the link, i was using a similar tool from the wheels1010 site or whatever its called.

the front wheels in my setup would be an additional 13mm to the inside as well as 13 mm to the outside, i just wanst sure if that was going to be ok or not, hence why i was going to do the test with the stock rear wheel to get an idea before i ordered the new wheels and tires.

importfan, i dont have the 17x8 option for the wheels im looking at. would love to see pics of what your car looks like with the 17/18 setup though.

Outlawlatemodel

i have a set of 18" oz 3 piece superlegerra and a set of 19" oz superturisma if your looking, 574-274-2543

Forget about these calculaters handling with mm... the problem is, a 225 tire can be 218mm or 240mm or any other value.
My new 285/30-18 tire for example is 309mm wide (probably it is the widest 285 available). Now I try to get my fenders ready for the wheel.

was reading you posts guys and thanks so much .. just researching and looks like my set up is safe I have 18x8 ET31 front and 18x9 ET35 rears AMG monoblocks
