Hey guys, brand new to this site...but love how helpful everyone is. I bought some staggered wheels and tires for my 2006 s500. The rears are a 30 offset with Pirellis 275/30-20. They only rub when I hit a dip at higher speeds and going up driveways. The barely rub, because I can see the rubbing on the edge of the tires on both sides, mainly on the passenger rear side. I called the company from which I bought the wheels and the company who makes them and they stated that that offset should work because they have done many w220. I am going tomorrow to get my fenders rolled by a place called TWS ( The Wheel Supply) here in southern california. I alot of good things about these guys and they said that even though the rear is aggresively...he will still be able to roll the fender enough and shave the inner bumper lining for it to work. What do you guys think about anything I have said..let me know your opinions....

The correct offset for the rears is 46 (44 for front).

The wheel company said they will exchange the rear wheels for a 42 offset. My questions is will it look weird with a 42 offset on the rears on 275/30-20 and the fronts stay at a 30 offset with 245/35-20. What do you guys think? Would it be obvious that the rear wheels are in 12 mm more? Should I use a small spacer to make it look better?

You should get the right wheels for the front too.

nguyenbio

What would be the right offset for the front too?

whoover

Here it is again.

while this may fit, this answer is too general without addressing width, tire size (sometimes brand as sidewalls may vary) and how low the car is.

i do agree to avoid using spacers if possible especially if the wheel you're using is available in various offsets. however, sometimes spacers are necessary to fine tune your stance.

These are the factory numbers for staggered 18 and 19-inch wheels on this chassis. The factory 19's, for instance, are 245/40-19 fronts on 8.5X19ET44 wheels and 275/35-19 rears on 9.5X19ET46 wheels.

The OP's 275/30-20 is a reasonable +1 fitment from the factory 19 setup, and would use the same offset. Similarly, I assumed the proper +1 fitment for the front, possibly 245/35-20, which would also take the factory offset.

30mm is way too low for any fitment with reasonable alignment.

I don't think it's too general. actually its more on point than off. IF he uses this offset, it really dosn;t matter if he's low, wide, or whatever, this WILL work.
Everything else is just a shot in the dark.
I agree with NO spacers as well. ust get the right whell and eliminate issues with vibration.

okay lets
Staggered set-up
Car is stock height!

Rears:
Tire-Pirelli Pzero Nero M+S 275/30-20
Wheel- Presently 20x9.5 with a 30 offset ( Barely rubs)
Company will exchange to a 20x9.5 with a 42 offset

Fronts:
Tire- Pirelli PZero Nero M+S 245/35-20
Wheel- Present 20x8.5 with a 30 offset. (No rubbing)

I love the look of the present set-up except for the occasional rubbing. If I can roll the fender enough and it stops rubbing, is there still a disadvantage or harm? I also am wondering how it would look if I decided to go with the 42 offset for the rears but kept the front at 30. Would it look odd? Never had experience with this before. Someone also mentioned alignment if the fronts stayed at 30. Is this really an issue?
Pleae let me know ASAP. Going to get fenders rolled tomorrow.

stevedel

IMO, if you can get enough clearance by rolling your fenders you the extra 12mm won't harm at all. However, a disadvantage to this would be that if you choose to sell the wheels down the road, you'd be limiting your number of potential buyers w/ a W220.

IMO, since you're running a staggered setup it wouldn't matter because you won't be rotating wheels front to back. If you like where the wheels sit now and you don't have rubbing issues, it's your perogative to use them or not. The only difference I can imagine would be lip size since the backspacing will be slighly different.

nguyenbio

Anyone else??

What is it that you'd like an opinion on? You seem to consider wheel offset as a cosmetic thing. If so, what do you care what other people think of the look? If you like it, fine.

The real problem, of course, is that offset is not about look or even preventing rubbing. It's a fundamental steering geometry parameter. Running 30 rather than the factory 44 means your front tires' centerpoints are 1/2" more inboard than intended. This will affect handling, roadholding, steering feel and tire life.

This is on top of the fact that your 245/35-20 is 3% larger in diameter than the factory recommended 245/35-19. The proper +1 tire is 245/30-20, which is within 1%.

Your steering geometry is all screwed up. But if you only care about cosmetics, just go with what you like and don't take any curves very fast. If maintaining or improving the engineering characteristics of the W220 chassis is important as well, go find a competent tire and wheel specialist.

Im using

20x9.5 35 offset of the rear with 275/30R20

20x8.5 35 offset of the rear with 245/35R20

Never have a rubbing issue

my06clk

UR wheels have a 2 or 3" lip. That's why your offset is 35.
AND the issues are with lowered cars. urs it still way up in the air to even matter.

steven07

will 18x9.5 ET30 cause probs?

Arlen777

Exchange ur wheels to higher offset and if u decide to drop ur car prepare to pull ur fenders and modify front fenders.

Albert at TSW is the *****...he rolled my fenders by hand and the thing doesn't even rub at all. I was amazed at how he rolled the fenders with a heat gun and rubber mallet and it looked like it came from the factory. He stated that very few of his clients run such an aggresive offset, but it does happen...I happen to like the look of the flush tire and wheel set barely behind the fender. It looks totally awesome.
BTW, Albert's shop has been featured in many German and Japanese high performance magazines. Spoke to a few customers while I was there waiting and they have been coming to him with their Mbs and GT3s for years. You will actually have to roll the fenders and shave off a little plastic. By the way, did you know that the rear passenger wheel is staggered towards the rear a fraction of an inch more on the w220 for handling purposes in corners. That is the reason, why rubbing is usually more prevalent from the passenger rear with a low offset.
If you want Albert's info, let me know. You get alot of information from a guy who use to work at Brabus when they were still in Newport Beach, Ca.

Interesting! My car tends to rub on the back passenger side as well. Now I know why. Its time to get my fenders rolled.

My car is lowered and I'm running 275/30/20 in the back and 245/35/20 up front. Not sure on the offsets of the rims though.

westcoast5

good info! I always wondered why my car rubs only on the passenger side I have my inner plastic cut, (did it myself) just enough to give clearence for the tire but it still barely rubs at speed. I run 275s in the rear and I think my offset is 32 or 35

huh? most of the time customer wont mind if you roll and pull the fenders especially if you have some sick wheels, as long as they dont rub ofcourse,other then that they will not care, unless its done like poo ..

the only way you can harm pontential buyers it if you put your stock wheels back on and the car looks like a sucken battleship...

stevedel

I said that because the general consensus in this forum is to use a wheel with a factory offset than to use an agressive offset and have to roll your fenders to fit.

OP - have you posted pics of your setup yet?

Mr S430

It should fit no problem I had these asanti af120 staggered 275/30/20 and at first they did rub but checked it out and it was just rubbing from the inner bumper end, so all I did was grind down the bumper and that was it no more rub at all as you can see I tucked the rear wheels in that much at one point and didnt rub at all.

xliemx717

here is something to also think about. i have a 2001 S600 sport package, have run Lorinser LM5 19 X 8.5/ 19 X 11 for rear offset 38mm and never had a rubbing problem. why, because my car has the inner fenders rolled from the factory for the AMG package option code 774. need to check and see if you have this option. you can tell by looking in the trunk right side under the carpet. if the rear wheel wells are not rolled like mine are, they will rub. hope this helps.

vision808

Definitely roll and pull your fenders first. If you still get rubbing I would just choose a smaller tire. 265 or 255. On a 9.5 wheel this would give you a very minor stretch and give you the clearance you need. Getting the higher offset in my opinion will look like crap.
