I have a question for the wheel experts. I am looking to get a new set of wheels for my W212 and the only option I found on the wheels I like have 40mm offset.

My question is: will the following configuration rub at all or look bad in any way?

FRONT WHEEL SIZE 20" 8.5" 40mm TIRE SIZE 235x35x20

REAR WHEEL SIZE 20" 9.5" 40mm TIRE SIZE 275x30x20

Thank you

No, shouldn't rub at all. They might not be flush fitment, but it is easy enough to throw spacers on there to be flush. If you plan on lowering the car this offset might be just right to get the car down low without any rub. Maybe 3 mm spacers f and r would be just right to get it to -37 offset which in my mind is just right.

Thanks for the info, I'm not planning on lowering the car so I just might have to get spacers to get flush fitment...That said, will the car look odd in any way if I install 20" wheels and not lower it?

For front fitment, you maybe touching front perch due to higher than optimal offset with 235/35 tires. I would use 5mm H&R spacers part number 1055665 for et35 to be on a safe side (also will look better).

For rear fitment, you will be perfectly flash with fender. Nothing should be done there.

Thank you for the info, does that mean that the correct offset for 20" wheels 8.5"F, 9.5"R should be 35mm F and 40mm R? I have read in the forum that the correct fitment was 35mm all around

Thank you

Different people interpret differently what "correct" means. Most here (me included) want flash fitment as much as possible.

ET35 (or even a bit lower) will result in flush front fitment for 8.5" wide wheels with 235/35-20 tire you're using.

ET38 will do the same for rear 9.5" wide wheel when used with 265/30-20 tires. Since you're using 275/30-20 tires, any offset lower that 40mm will push wheels passed fenders. ET40 with 275 is as aggressive as one can get - a bit higher offset would be better, but not any lower.

Bottom line - your wheels and tires are "correct" for (nearly) flash fitment, but front most likely may require 5mm spacers.

I am looking for flush fitment, therefore 35m front and 40mm rear should be the correct measures for flush fitment given the tire sizes I'm planning on using correct?

threeMBs

Yes, for tire sizes you're planing on using, ET30-35 for 8.5" wide front wheel and ET40-45 for 9.5" wide rear wheel.

Thanks for your input, this information helps a great deal.

Not at all.

One more thing if you don't mind, since I haven't yet purchased the wheels or the tires...which 20" setup would you recommend for flush fitment if I'm not planning on lowering the car...or will a 19" setup will look better?

threeMBs

OK.

This is what I have on my stock hight rwd W212:

20" - 235/35-20 on 8.5" ET32 front, 265/30-20 on 9.5" ET43 rear (flush fitment requires ET38 with 265 tire, but spacer less than 10mm can not be used on the rear hub). Front 100% flush, rear 5mm "in" (but 275 tire, that most others use here, would result in about 100% flush fitment).

and

19" - 255/35-19 on 8.5" ET43 front (I use 5mm spacer for ET38 that gives me alsmost 100% flush front fitment), 285/30-19 on 9.5" ET43 rear (almost 100% flush rear fitment).


IMHO, 20s look better, but I feel "safer" when I'm on 19s. I switch them back and force twice a year.

Thanks again, I now have all the data to make a well informed decision.

Hello, I also have some questions on making 20 inch wheels flush on a 2011 E550 4 Matic. I have 20x9 wheels front et 40 offset and 20x10 rear with et 42 offset. I have 235/35/20 front tires mounted on the wheels and have 275/30/20 tires that have been ordered for the rear.

I'm sure that I will need at least 5mm spacers in front but was wondering is 10mm spacers would work on the front since that would give et 30 offset. The 5mm spacers would give a et 35 offset.

It looks like I would have to keep the rears the way they are but was wondering whether the 275/30/20 tires with the 20x10 wheels et 42 offset will be a problem or rub.

My hre that were built for a w212 e63 are 20x9 29et and 20x10 et 39

I run a 255/30/20 and 295/25/20

This is an aggressive figment that pokes just a bit. No rubbing but very close. Tire brand is very important when u have aggressive offsets

hypekills187

how would 20x8.5 et38 and 20x10 et 43 work out for w212?

Sounds about 3mm safe both front and back... so good call. Personally, I don't like to get super close to the fender. And this setup is pretty nice. Also allows for slight variance in tire models. Good call.
