325iX Wheel thoughts

[nando]

ET27 for a 7.5" and a 225 is too low.

[saurey]

What's the Perfect size for an IX with these considerations?
17"x7.5 (Or 7 if 7.5 is too aggressive)
1.5" HR lowered suspension
225 tire *
No bottoming out/rubbing.

I was peeping the Beyern Mesh's but they are all ET27 which is too low for IX.

Great thread so far, thanks all so much for all the info.

I was comparing euroweaves to ix weaves. I think the track is pretty much the same.

What is the track of the m3? The front would be pretty comparable

[Mystikal]

the hub is more than 6.5mm, track width is based on the wheels/tires. So the hub sticks out more, plus the wheel is higher offset (41 - 24 = 17mm). You have to add the two together to figure out how far the 325ix hub sticks out, it's a lot more than 6.5mm.

The rear hubs stick out 17mm more than a standard E30 (since it has the same track width), and the front hubs stick out 23.5mm more.

Now you can see why I say an ET20 wheel doesn't work on an ix, because it's really ET-3.5/ET3 (front/rear) in comparison to a standard E30.

running an ET35 wheel on an ix is comparable to running an ET15 wheel on a standard E30, only you have the additional concern of strut and suspension clearance to deal with because everything moved out, not just the hub.

You're right, using the track figures my estimate is incorrect. But, the E30s in that chart are NA models using 14" wheels (majority being +33, so I assume that's the measurement they used). So the front hubs would be 13mm [track] + 16mm [wheels] meaning 29mm overall or 14.5mm per side. The rears stand at 0mm [track] + 16mm [wheels] meaning 16mm overall or 8mm per side.

Thank you, this is now the right info, what i need it now.
This somethig i think also, nut my brains dosent work, because of incomplete data. This is now lighted up the whole thing.

...per...side

Sorry 13divided by2 is 6.5mm per side
Yes, that is that number, as you say earlier

I do not know if that's right then, but hardly the owner manual Would fool

[Mystikal]

...per...side

[litu]

But my ownersmanual says that normal 325 track width is 1407mm and is 1420mm, 13 mm is wider

In there is stock rear wheel e30 1407mm and ix is 1420mm. Ok i remember wrong, but the difference is just 13mm.

On the previous page I made a post a few pictures ix 17 inch rims

That's funny, if you search my posts I've been saying for years that iX track is about 6-7mm off. Looks like it's 6.5mm.

[nando]

I think that site is wrong, the rear track is different too.

[litu]

well, the struts are more upright, and there are differences in clearance around suspension components.

but, generally, the ix will have a higher offset. It's more than 5mm as well (I'd have to dig up my manual, it's listed in a wiki but the numbers look wrong).

Stock iX wheels/tires...
15x7 +41 205/55-15

New size:
17x7 +35 215/40-17
The wheels will stick out 11mm further toward the fender and 1mm closer to the shock. They will occupy the same exact space rotationally, and are within 4mm of rolling diameter. The speedometer will be off by .3mph at 60mph, which is negligent.

I understand quite clearly the offset and wheel differences. What I want to know is, does anyone currently have some 17's on their iX and have pictures and specs on wheel/offset/tires

If I understand correctly that those is about the same E30 vs ix. So, if think tires/rims size almost, not stock tyres/wheels size. The only difference is that the track width of the front, but this clarified things.
I'm sorry if I can not explain clearly :)
