Verifying preferred 18” wheel fit

[sig425]

These are E class monoblock wheels with the following measurements.
Diameter: 18"
Width front: 8"
Width rear: 9"
Offset front: 31 mm
Offset rear: 35 mm
Bolt pattern: 5 x 112

They should work fine on my c43 right?

Thanx for the specs. So many people don't provide the base info needed so others can help them... ;)

You're narrowing your track by 9mm total front to rear this way, with all but 1mm of your added rear rim width [11mm] extending inside the wheelwell; going wider in the front and narrower in the rear.

I experienced pretty bad oversteer when I did this using 8" OZs front and rear. I widened the front and narrowed the rear, and the car started spinning out on quick sharp turns. I had to add a spacer in the rear; 15mm in my case. You shouldn't rub on the inside wheelwell cover extending 11mm into the wheelwell. It depends on your drop and others who run them whould be able to say. I would think it would be much better if you ran a rear rim with offset in the mid to high 20's. (surprisied the 18" E monoblock offset is so high in the rear!)

On the C43 stock 7.5" AMG monoblock is 35mm and stock 8.5" is 30mm. Use this to compare how much wider your rim track will be both front and rear and you'll see what I mean:

With your selected rims, it says....

FRONT:
Inner Clearance: 2mm LESS (the inside of the wheel to the strut housing)
Outer Position: EXTEND an extra 10mm (position of the outside edge of the wheel)

REAR:
Inner Clearance: 11mm LESS (the inside of the wheel to the strut housing)
Outer Position: EXTEND an extra 1mm (position of the outside edge of the wheel)

I think for the best handling you'd want to use a 10mm spacer with them myself.

I currently have this Monoblock setup on my C43. Many others have done the same.

Do you know if your rears are the 35mm offset? I know carl (coolcarlskic43) runs them too. Just don't know if you and he and all others have a 35mm rear offset.

Yes, my Monoblocks are 31F and 35R.

ALOT and i mean ALOT of people are running those wheels with those specs and it works out just fine.

make sure however you DO NOT run the E55 size tires, the will not fit

you need

225 front and 255 rear tire sizes

good point jnolte, i guess we just forgot and left those details out......that would have been harsh and a waste of money, LOL

thanks guys.

where can I get the required spacers?

[SLAMMED_C]

digging up an old post!!!
I was wondering if 18x8 et30 and 18x9 et33 would fit my car.. I was reading the above and it seems they should.. maybe use spacers to push them out slightly?
I know ideal offset is 35.. maybe I should use some spacers to get them to sit right.

I think the lower the offset, the more it will go out. You don't need spacers for those wheels, slammed_c.

Yeh I just realized that.. I would have to get the wheel hubs machined down a bit.
