I and XI wheels interchangable?

Hi all,

I'm trying to revert my car to stock. I found some stock wheels that came from an I (RWD) but was wondering if these are interchangeable with XI? I heard that the XI had a slightly different offset for their spoke 45s.

They should be fine, but don't put a staggered set on. M3 wheels wont work either.

offset shouldn't matter, it's whether the set is staggered or not (risk of variation in rolling diameters)

For the record, my (German) instruction manual that came with my 325xi (I live in the Netherlands) does have the wheel specs and staggered is "allowed" by BMW.

I would never go with staggered due to bad experiences on a previous (non-M) e36.

The staggered doesn't matter as long as you are SURE that the overall wheel diameter (rim and tire included) is exactly the same. The biggest downside to staggered is that it will increase your understeer which the xi already has enough of. Stick with square, your smile will thank you.

I just want to stick to the stock 16inch spoke 45's but I recall back in 04 when my cousin bought a regular RWD version, his spoke 45's were slightly smaller than mine but I think this thread just confirmed that I misinterpreted everything. Thanks!

Running mildly staggered setups should be just fine if you keep a square tire setup. I'll let everyone know once I get some road time on my new winter setup, I got some e90 sport wheels, 18x8 in front and 18x8.5 in the back but they have offsets in the mid 30's to make a more aggressive stance similar to my BBS CH's.

One tire will be slightly stretched compared to the other so the diameters won't be identical, but I believe the difference will be so small it shouldn't affect anything. I know when I had a tire disintegrate on a set that was about 50% worn, I only replaced the tires on the front which would affect the overall diameters too and I noticed no ill effects.

True - staggered set up works fine on an xi so long as the rolling circumference is the same. Its just as essential for ABS not only the all wheel and DSC. Suggested (optional) set up (direct from BMW for XI in Canada) is 225/40/18 front and 255/35/18 back. I run these on 8s in the front and 8.5s in the back with 47 and 50 offsets respectively. I'm and everyday driver, don't track my car but like the staggered look so for me its mostly estetics. Downside of course is it limits your ability to rotate tires. That said I run winters on stock 16s with a square set up for 5-6 months of the year and summers on my 18s for the balance so my rubber is going to last longer than if I was running an all season on the 18s year round. Check out this link the difference between these is 2 revolutions per mile or 0.2% difference. The difference is so marginal, it would never impact the AWD system negatively. Arguably, uneven wear on your tires could be greater than this. That said, BMW probably is the most forgiving in this require, Subarau and Audi are much more finiky. At some point I may swap out my fronts for another pair of 8.5s and put 255s all around but for now I'm happy.

I want to put a staggered set of wheels on an, have been looking around at what everyone has said that there running, on their XI. I still don't understand why some choose to run a 40 series on the front and a 35 on the rear? why not a 35 or 40 series all the way around? By having to different side wall sizes create a different wheel rotation?
Example 225/35/19 Front on 19x8
225/35/19 Rear 19x8.5 (slight stretch)
I've read some one runs- Front 19x8.5 225/40/19
Rear 19x9.5 225/35/19

Its all about rolling diameter. If you run all the same widths say 4 x 225 then the profile/sidewall should all be the same 35s all around or 40s all around but if you have different widths 225 front and 255 back you need to run a different profile/sidewall in the back. The profile/sidwall is 40% of the width so 40 on 225 is like 35 on 255. It is absolutely essential that the rolling diameter is exactly the same otherwise you will mess up your all wheel drive and will cause your DSC and ABS not to work. I'm sure you have the last bit of your post wrong, I doubt anyone would willingly run Front 19x8.5 225/40/19 Rear 19x9.5 225/35/19. Are you sure that the back wasn't a 255 because that would make more sense

It may have been a 255. I know he had M3 wheels on, I don't remember where i seen it on the forums tho. I want a set of LM reps but with a lip on rear if possible? an don't fully understand how to choose the proper offset. An i have used the search button. Just would like a good answer for fitment, with or with out spacers.I want this look for wheel set up http://forum.E46Fanatics.com/attachm...1&d=1293165930

I run 225 x 45 front and 245 x 40 rear on 17 inch staggered wheels. I understand this was an optional wheel/tire setup with staggered Style 68 wheels in Canada when our cars were new.

I have exactly Shadow2 in Canada.325Xi-2002, very good ,only in dry warm time, Winter go back to 205-55R16 winter tires.
Really good, smiling when see other car stuck on heavy snow or icy. Now my son drives Xi.
And the same with X5 couple years ( X5 pre 2005 is exactly AWD of E46 XI).

Very satisfying when you pull away on a green light as if you were on dry pavement whilst others sit and spin through the intersection! I go back to 205/55/16 for the winter and its like driving a 4x4 truck except better because the xi has a low centre of gravity..........truly the best of both worlds!
