Widest possible Rear Wheel setup

Hi,

I would like to fit 18x10 ET25 rim under my pre-lci E92 for the rear with 285/30 tires. Is it possible with fender rolling, or would the fender roll need to be aggressive?

Do you have stock suspension or aftermarket (car might sit lower)?

You would most likely rub with that setup even with fender rolling.

Ive got 18x10s et25 on all 4 corners on my e92. Youll need to roll fenders pretty badly and a little camber over stock. Im on a 265 35 tire. Wouldnt reccomend anything bigger.

I would do et35 ( or et38 ) with spacers m probably 12 mm and you should be fine.

Better to do fine tuning with spacers than get stuck with a rim that is going to rub all the time.

Yeah I got higher offset and fine tuned with spacers only safe way to go for sure... just make sure the room to play with spacers is from 10mm to 20mm for hub centric i would never f*ck with those bunk non hub centric spacers...

Why push it to it’s limit or beyond? A 265/30or35/18 on a 9.5 ET 32 or 35 is a nice look on the rear. Why cut or pull metal and negative camber if it’s not necessary?

I think I will go with an 18x10 with ET43 and 285/30R18 tire for maximum traction

Probably not comparable (as pre LCI have less space in the rear I think) but I have an LCI E92 and I have 275/40's on my 17x9 ET30 Apex in the rear and I have about an 1" to 1.25" of gap with stock xi suspension and springs. Will be a bit lower in the next couple weeks with sport suspension and springs.

The only bunk spacer for an E9x is a 10mm one. (Okay, fine, 8mm is bunk, too.)

Et43 is good for the rear with a 285, u might even get away with no fender work, tyre depending as some run wider than others at the same size. Let us know how u get on. :-)

What make you think that 285/30 will offer maximum traction?

I run 275 on my 19s with no problems at all. You might get some rubbing with 285.

^^^^This. I completely agree with Socket. I run 265 at all four corners (for many years now) so that I can get a little better longevity with rotating all 4. I like how 265 up front drastically reduces understeer. I dont think 275 up front would fit...

I'm running 275/30-19 on 19x9.5 in the rear on my car with 5mm spacers.
No rubbing unless I have heavy people in the back and I hit a big bump.
I have a 2008 E90.

By maximum, I meant that I can't really fit a wider tire in there. LSD is being custom built and I am running Yokohama ad08r and I would also be running ad08r with the new set up. So can't get any better traction than this for the street.

You can fit wider tire. However wider does not equal more traction. Use contact patch calculator to compare the tire sizes that you know fit.
