Hello guys,

I have a BMW e91 M Sport from 07 which i've found some new rims for.
But im not sure if they will fit properly?

The car have the M Sport suspension option, and the rim model is Japan Racing JR20

Front rim - 19" 8,5" width, ET35.
Tire - 235/35/19.

Rear rim - 19" 9,5" width, ET35.
Tire - 265/30/19

will they fit good? Or do i need spacers to make it look good relative to the arch?

Here is what I have setup with ZERO spacers and ZERO rub and ZERO low. Fronts are about maxed out on width of what you can fit under the fender, rear is the same.

You can run 275 on the 9.5 but i'd stay at 265. Wide enough. Use this as a reference. If you have a 20mm additional offset on a 9.5, you may need spacers to achieve a filling look.

For my setup the 275/30/19 was a better diameter match to 235/35/19.

For the Michelin PS4s and former supersport the contact patch was very close between the 265 and 275 (only listed as 0.1" in the specs even though the size implies more width). Note that they do list it as 1lb heavier though...

Would be possible to run 19x8.5/19x9.5 both ET 23, on the stock M Sport suspension then ?

Can I run your setup on my 328xi wagon or will this cause difficulties with the AWD system ?

punch 'em in here - https://tiresize.com/calculator/ tells you all the tire things. A 1:1 tire setup for 19s are
235/35/19
275/30/19

so play with the numbers for 18s. I think you have to stay within ~1.5% on the xdrive. Double check me on that.

Right now I have a 265/35/19 (220M, straight off an E92 M3) on the rears of my e92 335xi - but I'm running xDelete (otherwise its off by ~6%?) ...and the 265/35s rub like hell. I'm running m3 wishbones and guide rods (they play no part in this) but most important thing to note these wheels are a 23mm offset, most others are more -- and I haven't done a mock up to check my math, but I'm almost certain a ~30mm offset would clear it.

The tires I have now are in good shape so I'm REALLY trying to hold off getting 275/30 to make clearance ...or I might just roll the fender. It seems counter intuitive, but it's -0.8" diameter difference and a .4" wider tire.
