I have a 2010 535xi, I recently got a very nice set of style 199 wheels 19x8 et37 F & 19x9 et39 R, I’m thinking of putting on 235/35r19 on the front & 275/30r19 rear... that puts me at a 0% difference. But I’m wondering if the rear tire will be ok in the width? I also have 15mm front spacers & 20mm rear spacers
will I be able to use them still? Another thought I had was I could just put 235/35 all around but I wasnt sure if the rear wheels being 9” would effect that in a negative way with the rolling circumference duet to minimal stretching? Anyone with any gong the above mentioned setups I could really use your help and photos for helping me choose what direction to go. Thanks!

My car.


Style 199’s

 

Not one person on this entire forum can chip in?

 

I am running 245/35/19 front, 35ET,8.5 wide and 285/30/19, 33ET, 9.5 wide in summer.
Winter is stock staggered 124s at 245/40/18, 8 wide,45 ET and 275/35/18, 9 wide, 55 ET with 12mm spacer in back for winter.
I dont think your spacers will work on a Xdrive
Does that help?

 

Thanks, after a TON of googling and reading. I just decided to go with
235/35/19 Front
275/30/19 Rear
they have a 0% rolling circumference. Same sizes just wider in the rear, Fingers crossed!
I have the spacers on currently and been running them with zero issues. From my research spacers are ok on xdrive... am I wrong?



Before spacers

Before spacers

With spacers

As long as the tires dont hit the fenders, spacers are cool.
You just need to worry about the front = back wheel diameter on the Xdrive
Stock for me with the 245/40/18 and 275/40/18 is close at .54. It must be okay since BMW went with that size from the factory.
My summer setup is .08

 

Good morning, i bought a set of CSL wheels Fronts: 19x8.5 ET 35

Tires: 235/35/19



Rears: 19x9 ET 40

Tires: 275/30/19



Bolt pattern: 5x120

i was told, this set up would mess up my xdrive system. Have anybody rant into any issues with a setup like this?

 

You should be okay.
