Hi
I just ordered new 20" wheels for my e43.

• Front: 9,0x20 ET35 + 15mm spacers
• Rear: 10,5x20 ET40

I know, that the e43 has this tire combination

• Front: 245/35/20
• Rear: 275/30/20

Now my main question is. can i use on the rear 285/30/20 instead of 275/30/20?
does anyone have experience with this?
my concern is because of the 4matic.
next thing is i want nothing to brush against the fender

ty for all ur answers.

 

Your front needs 18mm spacer at least to clear the suspension components. As it stands now (without any spacers), your wheel is 28mm closer to the suspension components.

Your rear can do 285/30/20 ... but It will rub already even at 275/30/20 I believe because your wheel of 10.5 inch wide will have extended it out by 28mm (without any spacers), also you are going to be 10mm closer to the suspension components. If you do a spacer, that will extend the wheel out even more which means it will rub the fender for sure.

Is there anyway you can do away with these wheels ? Your wheel shop should have done the calculation for you before you are to order them.

just my 2 cents.

 

If I were you, I would consider doing

F: 20 x 8.5 et 15 255/35/20
R: 20 x 9.5 et 45 275/30/20

No spacers are required. The wheels (front & rear) would have extended outwards by about 10mm.

 

Yeah as Bobblehead said, you want to try and get the wheels in the right offsets instead of running spacers.

I run 20x9" 255/35/20 & 20x10.5" 285/30/20 on my E43 - those sizes keeps you within the variation allowed with the 4Matic.

 

Curious if you ended up getting spacers - I wanted to pick up some from H&R but for some reason they tell me they don’t make it for the e43.

anyone know of spacers should be interchangeable for all 2017+ w213s?
