19x9.5 +49 offset help?
I am thinking about getting this set of wheels for my 340i x-drive. However, I am not sure if it will work or not. I have seen others fit 19x9.5 +35 offset on these cars. The wheels I am looking at are +49 offset. By theory, it should work with a 15mm spacer correct? Or has anyone tried this and found that the theory does not work in practice? I am considering buying one wheel and trying it out. If anyone has any insight on this please let me know. Any info will help.
Specs: 340i x-drive stock suspension (planning on dinan springs) 19"x9.5" squared +49 offset 255/35r19 Michelin Pilot 4s (subject to change) Will spacers make these fit? What size spacer? How about the scrub? Would the change be worth it if it's about 15mm scrub after spacers? |

Why would you recommend not running spacers? I have seen many people run them. Are there inherent issues involved that I may not know about? Unfortunately the wheels I am looking at only come in that size or 8.5 at +35 which I am not sure will be enough rubber as I am planning an 800whp build.

imo for 800whp you should run 8.5" +35 with 245/40/19 front and 9.5" +49 with 275/35/19 rear. or run square 19x8.5 ET35 with 255/35/19, like this...https://f30.bimmerpost.com/forums/sh...ht=bimmerguy91 . Last edited by alohasurftoad; 05-17-2021 at 06:18 PM.. |

I definitely prefer to not run spacers. However, the 9.5" wheels are what I wanted to run and for the reason of not wanting to run spacers I am still unsure. I have seen the 255 on the 8.5" but was unsure about the fitment and bulge of the tire. Not saying that it wouldn't work but that it may be a little silly stuffing such a big tire on the 8.5" width. |

I have aftermarket wheels that required spacers. I almost returned the wheels because I would rather not deal with spacers as others mentioned. But I liked the wheels so much that I decided to keep them. Wheel stud conversion would make your life much easier if you decide to go with spacers.
9.5 inch wheels with 15mm spacers might be too much for the front. I think you will be running into rubbing issues. You might want to ask around with someone that has this type of setup. Good luck! |

OEM 442M, 403M and 704M staggered setups have 255/35/19 on 19x8.5 at the rear. it's the minimum width required for 255/35. if the concavity of the 9.5" is the real reason you want them over 8.5", i understand. |

It's more so the contact patch that I am after which is far different between the two.
Looked up the scrub again. With the spacer the scrub radius is the same as stock. Last edited by sm32589g; 05-18-2021 at 12:03 AM.. |

Correction: the wheels that I'm looking at, alternate size is 19x8.5 but et30 not 35. Has anyone ran these with 255/35r19 successfully? I think I've seen one guy run a +35 with a 5mm spacer, but I would like to see if more people have run it also with any luck.
