Lightbulb Guidelines for E90 rims on E46?

Hey all,

I searched for this topic and I see there are a ton of threads about this already. However, it seems that in the existing threads, people are usually asking about very specific cases (which might be why there are so many).

Would it help to make a more general thread with broader guidelines for fitting e90 rims to an e46? That way, people with this question can consult a single thread rather than asking about their specific case every time.

For example, what are the criteria that determine whether an e90 wheel will fit on an e46? Size, offset, etc? Right or wrong, here's what I dug up with a bit of research...

------

Diameter
From what I can tell (correct me if this isn't right, noob here), safe sizes are 16-18" on a stock 32x, and 17-18" on a 33x (obviously fit tires accordingly). 18+" looks like it can work, but at your peril, as tires could rub depending on your setup.
(see this database: http://www.linquist.net/motorsports/bmw/wheels)

Offset
This wiki suggests that acceptable offset is between +35 and +50.
http://www.bimmerfest.com/wiki/index...Wheels.2FTires

Would it be a problem then, to use certain e90 wheels that have an offset of +34, or is that negligible?

Width
My stock wheels are Style 45 (http://www.bmwtips.com/tipsntricks/w..._wheel_045.jpg), which are 7" wide according to a few minutes of Googling. The wiki and database seem to suggest that anything between 7 and 8.5" should be safe. The database shows cases of 8.5"-11" width, but the wiki does not recommend it.

------

Please feel free to correct / contribute, hopefully this can help others who are searching for fit guidelines in order to assess how e90 wheels might fit with their e46. I am by no means knowledgeable about this (just Googled furiously for a while), but hope that we could build up a little knowledge base with people weighing in about this. Hopefully I'm not way off base thinking that this might be useful!

im running 19x9.5/10.5s with an et of 20/22 so it can be done... weather you want to pay for the tires, and do the supporting modifications is entirely up to you... ive had OEM M3 wheels on my 328, 3 sets of staggered 19" aftermarket wheels.... The wheels rim running now work for both e46 m3s to e9x m3s.... its all about what you want i suppose... dont let google or wiki tell you otherwise... because people are doing it

I'm running a 17" square setup of 159's 17x8 et 34, tires are 225/45. I will be running 189's in the spring 18x8 et 34 and 18x8.5 et 37. I've already test fitted them and there will be no issues with the setup.

My 197s are 18x8 et 34 and 18x8.5 et 37. I am running the stock 225/40 front and 255/35 rear tires and I do rub in the back on dips, road humps and turning into off-kilter driveways.

Now that deer season is over, I can take the time to figure out exactly where they are rubbing, and see what can be done to fix the prob. I'm not sure if they are hitting the fenders or the inner lining. I'll update this once I figure it out.

FWIW - I love the way they look and don't plan to change them.

E9x ///M3 replicas from ModBargains.com.

18"x8" front and 18"x9" rear. ET40 on both. Tires are 225/40/18 front and 245/40/18 rear.

No rubbing, scraping, etc. Just great handling and great looks.

The wheels fit fine. In some extreme cases they could rub on the fender that can be easily fixed by rolling the fender.

E9x non-m wheels should all fit fine without modifications.

I ran all style 197 rears (18x8.5 et37 w/ 255/35/18) on all 4 corners with no issues. My coilovers did require a spacer up front, but my stock style 44's need a spacer up front with my coils also to prevent rubbing on the strut.

My Ride: E46 2001 330i
I installed a set of E90 staggered wheels 17inch on a E46 (2001 330i) - they fit perfectly and look great. I took the car for alignment and the tech said i need to change some bushings and strut mounts as they were damaged, bent.... Could the E90 wider/staggered wheels cause this issue? (i dont think so, but then again I know very little about this), perhaps it was just time to fix and I had not checked since its the first time I am aligning this vehicle (new owner)... any input much appreciated!
