I want to start with an apoligy, because I am pretty sure this topic has been beaten to death. Its just that I am uncertain and unclear and confused about wheel options. And I have no idea what the offset is on my current wheels (they are aftermarket and came with the car), the only calculators also scare me. lol

What I know: Xi models are different than RWD thus we have to watch for offsets.

Now I have heard that running offsets as low as 25ish is fine (which i kind find bs, I feel like that is way too low) I also heard a safe range is starting from 35 the lowest to 45 ish. I also heard that running 30 to 45 is ok too without too much trouble.

Reason why I am asking is well, I need a second set of wheels for the warmer months, I only have winter tires/wheels. I found a few options. One particularly that stood out is someone locally is selling a set of Miro STP3 wheels with pretty much good tread left for at least a season of driving starting from now until November. The wheels also never saw snow.

These are the specs:
19x8.5 +35 and 19x9.5 +33

Now if anything I feel like the rear wheels might poke out a little bit. Just not sure how much. I dont want them to poke out a lot.

Let me know what I should be running in terms of offsets, If there is some thread buried deep in the forums that I have not found post it here. Thanks!

I hear what you're saying about the abundance of information on xi wheels. It all can be a bit confusing.

Here's the basics:

1. E60 xi vehicles require an optimal offset between 35 - 45 mm. Go lower and they stick way out or won't fit at all. F10 offsets go down to 30. (You didn't indicate what year your 5er is, so I'll assume it's a E60.)
2. All BMW sedan/coupe wheels since the 90's have required a 5 x 120 mm lug pattern and a hub bore of 72.5 mm.

If the aftermarket wheels you're considering don't fall within those specs, walk away. If the center hole is smaller, the wheel won't fit over the hub. If it's larger, you'll need concentric rings or the wheel will vibrate at higher speeds. If the seller can't tell you the offset, either have them agree for you to do a dry fit or contact the manufacturer for the spec.

This should help you out some...

But to answer your question quickly.. I would say the Miro's you got should fit fine if you have an E60.

I just literally put on a set of 19x8.5 square with an offset of 33 . In the rears I kept my 12mm spacer and it's just about flush which I love and that's the look I was going for. The fronts are pretty square as well, so that's a good fit.

Thanks for the help guys!

And my bad, I drive a 2006 BMW 525ix I know the bolt pattern and the hub bore. Just the offset that I get confused on.

I wanted concave wheels I had a set of Miro 111's picked out, just the offset was like 25 or something. Good think I didnt buy them. I still like the wheel, and they do have ones that fit an AWD model, I think the offset is around 35-38 ish. (These are topping my list in terms of price and look)

Id also love something with a lip. But most of the wheels that have a lip and look nice and fit the AWD model, run close to 1,200-1,300 for a set. Im willing to spend up to 900 for wheels alone. Tires are another 500 or so, so that already 1,400 for a wheel set up which seems somewhat reasonable (if brand new)

Finding used wheels around my area is somewhat hard, I like some of the OEM X5 wheels which i hear will fit but I would need spacers for. But people want a bit much, granted some of them are in a rough shape. Another wheel is the style 95s. I hear they fit as well. Not 100% sure. (would have to look up the offset on the bmwwheels webpage at some point)

If I cant find anything I do have someone thats selling a set of style 124's. But I dont know what offset they are. I have heard that there were 2 different versions of those wheels AWD and RWD. I would have to test fit them.

Not true. E39's are 74.1mm center bore. You can use hub centric rings to fit a 74.1mm wheel onto a 72.6mm hub.

JayArras

You are absolutely correct! I had forgotten that!

Be sure to put that in your "garage" for when we you next time. (But it's "xi", not the other way around.)

Because of the offset, I don't believe you can achieve much concaveness (if that's really a word) on an xi.

E53 X5 wheels (1995 - 2006) shouldn't need spacers. E46 (1999-2005 3 Series) wheels will also work on an xi.

Please DO, because they WON'T at ET 24.
You are correct. There are 124's available at ET 43. If they're OEM, that number should be stamped on the back, so no need to test fit.

Kasmo

Thanks for the detailed response! yea sorry about the Xi mistake lol. been a long day today.

Ill be checking out the bmw wheels page to see what my other options are for OEM wheels. Thinking I might try to find wheels with a lip instead maybe. Also Im hunting for 19" wheels, 18"s are good too. But 19"s are ideal.

JayArras

Maybe for looks, but not for ride quality. Good luck in your quest!

I honestly don't notice a difference in the bumps in the road going from the stock 17 to 19's. Cornering is a billion times better because of the less sidewall roll.

I thought about 18's but saw the difference on two cars and I liked the 19's.

Price wise, 19's don't get much cheaper than 950 a set. Although I saw some Alzor wheels at ECS tuning for really really cheap, but after shipping etc you're coming up to that same price.

Tires are also not $500 for 19" tires. Maybe on 18's when they go on sale.... you might be in for a little sticker shock.
