I have got myself a set of 20x10 inch mandrus wheels for my 2001 S320.

The offset of the back wheels are ET42 with a 10J width.

The company I brought them off recommened a 275/30/20 tyre for the back rims.


Ive got them all fitted today and went with a 285/30/20 back tyre because these were the only preworn tyres I could get closet to this size.


After driving the car and hitting speed humps, bumps, etc, the tyre setup is no good. The back tyres are rubbing all over at the top arches of the car and there is barely any space.


Ive known people on here to get 20" rims on then actully lower the car. The car is so low with these wheels on you can hardly fit your finger in all round the arch.


Im having to drive round with my suspension raised just to avoid the rubbing at the minute.


Do you think dropping to a 275/30 tyre is gonna make that much of a difference?

Also, what is the max size tyre I should be able to fit on this setup with the offset ive got. Im sure people have fitted 10.5" rims and even 11" rims without an issue on here.


Its dark now but I will posting pics tommorow of the exact problem.

my06clk

two issues.. 10"wheels and 285 tires.

If you use 10" wheels, you MUST have an ET of more that 42. 46 is better this will put the whell inside of the fender.

PLUS you can not run a 285 tire for this setup if you don;t want to rub. There was a good reason Mandrus advised to go with a 275 tire.
Also the 275 30 is the proper size tire for your car NOT 285 as some folks try to run with many issues.

If you want your speedometer to be correct and not rub, you should have 245 35 in the front and 275 30 in the rear.

And ET 42 on a 10" wheel sticks out waaay too far for your car. You should get a 9.5J with a 46 off set and it will be perfect. OR try a 46 offset on the 10J wheel.

my06clk, thanks for the quick reply.

I'm in a bit of a situation as ive already got the rims on, so its abit of a hassle having to get rid of what ive already got.


Another point is that the rear tyre walls seem to go straight up, almost like they stick out and go straight up. My friend has a CLS running a similar 20x10 wheel setup with 285x30 tyres, however his tyres are a Michelin Sport tyre, and the tyre wall appears to go up and then inwards, almost like the tyre tucks into the arch better.


Im going to order a set of 275's tommorow, more than likely brand new as tracking down 30 profile pre-worn is difficult.


Can you recommend a brand with a slimmer tyre wall. Should I even be considering 275/25/20 ?

m4xm1l10n

Well said !!!!!! even with 20x10 the 275/30/20 should cause no rubbing !!! but 285 hell yea !!!

baugh

Thanks for the heads up guys.

Do you think then that the 275/30/20's will be fine with the back wheels then?


The car already looks low as it is thats all, do you think dropping from the 285 to the 275 is gonna make all the difference?


Is there a particular brand of tyre that I need to go with, as I mentioned before, some seem to bed inward slightly on the tyre wall?

Will I need any fender/arch modification with this setup?

m4xm1l10n

No , it won't make a difference on the height , is it thought slightly narrow.

my06clk

I agree.. No matter what, with that 10J wheel you are going to have issues with a 42 offset.

M4M,

this is a bit off the subject but may have some use here..

I just did and experiment with my friends SL which is just like yours. We found that the rear fitment is the same. 275 30 20, and 46 offset for a 9J wheel.

the difference between the two cars is on the Front. The SL needs a 32 offset at least in order to clear the inner strut support. An Et32 wheel sticks out way too much on my S which requires an Et44 front to acheive the same look as the Et32 did on the SL.

The inner strut for the S clear the Et32 offset wheel by miles but the wheel is outside the fender well.. ( no good ).

THe Et44 off set wheel fits the SL but there is a micro hair between the wheel and the inner strut support ( no good either ). I don't do spacers... so we didn't go there.

Back to Baugh'e issue. He will need t least an ET45 or ET46 for his rear. an ET42 mounted flush against the hub puts too much wheel past the fenderwell. No tire is going to correct for that. 285 30 only makes matters worse.

You can try a 275 30 in a Nitto, or Toyo as they are more round, but I still think the wheel has to go.

Question for the OP...you are trying to buy used tires on new Mandrus wheels? I guess you can, but you may as well be looking for the right set-up as you will soon find out. Trying to make something work will only drag this out forever till you get the right setup. Madrus wheels are made specifically for Mercedes cars. Did you ask if that set-up was proper for your car? I'm surprised you were sold that offset.
No one shows an ET42 10J wheel for the W220 except OZ but the wheel design is different.

Hi again my06clk

I ordered the wheels from a local company who spoke directly to Mandrus. The wheels were shipped directly from them.

He spoke to them and they advised a 8.5J wheel for the front and a 10J wheel for the back, running a 245/35/20 on the front and a 275/30/20 on the rear.

This is definitely what they advised for my car after telling them the make/model/year as I didnt actully pick the size of the rims.


The only difference was that I didnt go with the brand new tyres from them as there are some cheap tyre shops round here so I wanted to get pre-worn first to make sure.


I can't believe you are now saying that im gonna have problems with a 275/30/20 on an ET42 offset, as this is what they have advised and the fact that it would give me problems with this offset and they have advised it is ludacris!

my06clk

It may be, but here we are right?

I checked Mandrus site as I am also a fan of their wheels and you are correct. They do state an ET 42 for our car. So there must be another issue or set of issues that exist in your case.

http://www.mandruswheels.com/appguide_20.html

You may be fine with the 275 30 tire. I should have asked what tire you were using in 285. I had noticed before that the Bridgestone RFT is a pretty beefy tire and caused me issues in the past so I don;t use them. They actually measure .5 wider than the same size tire in another brand.

Your car may be lowered too much for a 10" wheel also. less than 1 finger gap is a lot as it will be lower when you drive by about .5. I wish you could post a pic of the side view of your set-up so I can see the profile.

According to the measurements, that wheel should sit just inside of your fender well which again leads me to think more positively about the correct tire solving your problem.

Keep me posted....

m4xm1l10n

The wheels are fine , I also have the Mandrus on my SL 20x8.5ET25 AND 20x10ET30 , I came to a conclusion , like you said before MY06CLK , it has to be the lowering causing the problem . my friend does have the same wheels for the S with the ET42 and he is running 285/30/20 on the rear with no rubbing .

my06clk

I think so. Either that or those used tires were Bridgestone RFT's which a know for a fact are really wide at the sidewall and tread. I had to remove them from my car and put my a%$ on ice....LOL

I wanted some Mandrus Millenium wheels for my car..I thought I could sell St4's first. My garage is starting to look like a wheel shop again.

Here you go lads, pics as promised of my current setup and ride:

baugh

The first 3 pics are with the car with the airmatic up.

The 2nd 3 pics are with ride in normal, lowered position.


I would like to add my car does seem low, to say it was completely standard before I got it?

my06clk

Thanks for the shots.. The car is most definetly lowered. And lowered a lot. If it has adjustable links you can raie it just a tad and your problem will be solved.

Also you are running Dunlop Sport MAxx tires which are pretty stout. When you switch to the 275 series, you should be okay. I will check to see the specs on that tire.

if you raise your car slightly, you should be okay..

here is a shot of mine it's about as low as i care to get on 20's

https://mbworld.org/forums/s-class-w...gered-20s.html

Also here are some specs for the size you are using. The first link shows the dunlop tires specs.compared to other 285 series. click on the specs tab and look at the tire width and the section width..

The second link are 275 series tires.. look at the same widths for the 275 and you will see what your problem is.

Thanks m8, that was a great heads up again.


After checking the specs for most of the tyres shown there, the DUNLOPS im running actully have the highest section width, coming out at "11.7" inchs. Most others average out about 11.

This was much higher than the Michelin's, Yoko's and even the Pirelli's that im running on the front.


Based on the 275 specs I can see, and keeping the section width as low as possible, I should be ok with something like a Michelin or a Yoko.


My friend has a CLS running a 285/30/20 on his back rims, and he doesnt have a problem. He using Michelin Sport's and after looking at his tyres today, they really do 'Bed In' more on the tyre, as if they are centered towards the middle of the tyre. So they almost fit under the arches more. I think this type of tyre would help.


Finally, my car was brought completely standard when I got it as far as I can tell. Only 2 previous owners and the last guy was an old geezer.


Ive done all the mods myself, like the wing mirrors, grill, debadging, headlights, etc.


I'm not sure if the car can have links to re-raise the suspension?


The car has full service history from Mercedes and is a UK 2001 S320 CDI model. As I said completly standard as far as I know.

m4xm1l10n

baugh don't compare CLS and S two different cars when it comes to wheels , you can spank as much as 305/25/20 on CLS's with no rubbing problem

my06clk

Ahh that explains the height. The US cars sit a lot higher due to some ancient bumper rule that nobody pays any attention to except DOT. Change tires and you should be fine.

baugh

Right im gonna pick up a set of 275/30/20's for the rear and get them fitted hopefully on Sat.

Will report back with pics as soon as poss.

I have a set of 245/35/20 and 275/30/20 and I am rubbing all over on my 2002 S500. I have 20 x 10 and 20 x 8.5. What is the solution?

stevedel

couple questions:

• what is the offset of your wheels?
  
• where are you rubbing? inside or outside of wheel?
  
• are you lowered?

S600Keith

You've obviously bought too large for your vehicle. If you pay me a small fee and ship them to my house, I will take those 20s off of your hands and recycle them for you.

No trouble, really.

tusabes

Take your car to a custom wheel shop, they should know why it's rubbing and how to fix it. Sometime you need to trim some wheel well

It was just a little nipple that has to be shaved off. Not a big deal, problem solved! All plastic. Dremel is a wonderful tool!
