I think ET35 might work but ET25 is just too much...

but you don't mention offsets, just tires and width?

I know 18x10 et 35 will fit

curious if pushing to 25 would work or not...


i've done 19x10 et 30 before without any issues.

what do you mean ?

OEM offset is never the max as BMW is conservative

Sorry I don't completely understand what you're saying..... could you please be more elaborate?

I have personally fit a more aggressive wheel than OEM offset with no issues whatsoever

19x9 et 33 19x10 et 30 IIRC

Handled great, no rubbing against fenders or suspension.

Thanks

I talked to a bunch of guys here about what offsets theyre running, lowest i came across is lightning, hes running 9.5" rears +28.

So a 10" +34 would sit the same flushness.



I plan to go lower ;P

ET28 is exactly what I ran with my BBS CH 9,5 ET40 + 12mm spacer, with a PS2 265-30-16.
So a 10 ET34 will work, even a little bit lower up to about ET30 depending on the tire width (stretch). Wouldn't go lower than a 265 on a 10 inch... But than again I don't like stretched tires to much. To me it doesn't look good, the handling is poor and you lose a lot of confort.

Here are some pics of the BBS setup on my car (dropped on H&R)...
front : 8,5x19 et25 (35+10mm spacer) with 235-35-19
back : 9,5x19 et28 (40+12mm spacer) with 265-30-19









Grtz

Yup I agree

the lowest I'll go on a 9.5in now is a 265, let alone a 255 on a 10 lol

but they were free tires, plus only needed them for a short amount of time :P

Thanks for your pics!
