There are two 20mm aluminum spacers for the rear included if I require them.
If those measurements are correct, that makes both the front and rear offset ET47.625, which just might work. I'm not familiar with how much room is in the rear fenders, so you might want to ask LTBMW, since I think they're the only ones running extremely aggressive rear wheels and offset. The fronts will fit without any issue, though.

Alloy wheels offset

Hi Guys,

I need your advice on buying alloy wheels. I live in Austria and got my BMW F30 320i a few months back...have to switch to winter tyres in around 4 weeks.
I have been looking around to get complete winter tyres preferably 225/45 R18...the ones BMW sells are way expensive.
The ones I have found at few shops have rim offsets of 35mm whereas, BMW recommends 34mm for front and rears. Does that make any difference?

Thanks

Sorry for bringing this thread back to life.
Looking to buy a set of M5 reps sizes are Front 19x8,5 ET 35 Rear 19x9,5 ET37
I see they're a bit different from oem offset. Would that cause any problem?
Thanks

The front is perfectly fine. 9.5x19" ET37 rear is a bit aggressive, but nothing extreme.

What tire sizes do you plan to mount?

OEM 19" staggered tires 225/40-19 front and 255/35-19 rear will work with your offsets and fit nice on 8.5" and 9.5" wide wheels. If you want to go with a wider rear tire you might need to adjust camber.

I was thinking.

F: 8.5x19", 245/35-19
R: 9.5x19", 275/30-19

I could use some extra rubber jb4 and downpipe going in soon...
Suspension is stock.

275 rear will work on stock Sport Suspension. But the rear tire may visually be a tad bit outside the fender.

I am still struggling I can use my old rims or not. I go thru the forum and found that the new wheel offset for 19" is

Front 8X19 offset 36
Rear 8.5X19 offset 47

My old rims are on my current E90 which is
Front 8.5X19 offset 32
Rear 9.5X19 offset 25

I am not sure is it fit or not. will the rear extend too much and rub? As I really want to keep my old rims.
hi not sure about F30 offset but i can tell you that

front are fine no problem

rear better use 20mm spacer and your good too go
you will have an offset of 45 pretty close to 47 so is a gogo

best luck

bolts always the same in diameter can be bigger in lenght but dont know
using the 20mm spacer should have bigger bolts in lenght
If you use a 20mm spacer the rear will turn into +5 not +45. A spacer pushes the wheel further out LOL.
