Hey folks I saw a sweet deal on some X3 style 191M on my local craigslist listing. I want to jump on it but not sure if we have sufficient room in our wheel well housing and tires for these?

Would bolt these on my 2007 328xi E90

Rear
19x9 et51 (42mm further in vs OEM based on offset calculator)


Front
9x8.5 et46 (31mm further in vs OEM based on offset calculator)

Also what tire combo do you recommend for the above wheels?

Thanks a ton!!

25mm spacer in the rear. 15mm in the front.

wow et 51 I never saw an offset so high.

Yes, need spascers like said above, and new smaller tires.

[Vic3Driver]

cool thanks for the reply!! So what is the maximum inside clearnance we can get a way with front and rear? Based on the spacers suggest it seems...

For rear it is (42mm-25mm)=17MM inside clearance in rear
For front it is (31mm-15mm)=16MM inside clearance in front

Do the above numbers seem about right when compared to a stock 7" wide wheel setup with et34?

So are you trying to use the smallest spacer possible. The spacers I suggested would look best without rubbing or rolling your fenders.

[edirtaynine]

i would get 20mm spacers front and rear. but i personally wouldnt even bother with any wheel that would require me to run 20mm spacers all around. it'd be better to just invest in a set of wheels that fit properly from the start.

Sorry to hijack the post here but I've got a similar predicament:


I happened to come across a guy selling some sick ass OEM E46 powder coated 19x9.5 squared setup (two sets of rear) off his M3 - 255/35/19. As far as I can see, the 19x9.5 ET are 27...my E90 is 34 and 37 - 205/55/16, F & R.

Now, I see this type of question on here a lot, especially lately since I've been looking more. What sort of spacing will I need here for the front and rear on the E90? Is fender rolling necessary?

This is what the wheel offset calculator read:
Rear - 22mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 42mm

Front - 25mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 39mm


Is this ridiculous?

Any help is appreciated!

You need a 235 tire up front and the rear will be fine with either a 235 to match the front or a 265.

[Rainerelliott]

Oh, forgot to mention its an xi. Shouldn't I keep it square?

[bmw325i]

As long as the diameter is within 1%, you'd be good with 235/265 but if you want to do 235 all around that will work too.

[Rainerelliott]

Amazing. So with 235/265 or squared 235 I won't need spacers?

Just run 235 all around since the wheels are 9.5 all around. The fronts will be fine but the rear may be tucked in a little. He's running 9.5 et 30 all around.

If your going with a 235 you can add a 10-12mm spacer but it's not needed.

[Rainerelliott]

Well they're 27 ET. What's the possibility of using a 255 all around? Fender rolling?
