We are running 205/50-17 on 8x17et35 wheels. That fits without rubbing.
I will install some BBS RX 8x17et38 wheels, and I am considering 225/45-17 tires this time. Will that fit as well?

I have noticed that the stock 225-fitments are running with et43, so this will bring the tires 5 mm closer to the wheel arches.

I think it will fit, but it would be nice if somebody else has some experience and can confirm it.

et43 with 8" rim? Sure no problem at all.

No, the stock wheels with 225-tires are et43. I will be running et38.

Kinda bumping the thread here..

I'm running 19x8.5 ET40 in front (225-35) and 19x9.5ET45 in the rear (255-30). It also all depends on the type of tyre you're running. Some are less high or less wide than others.
I have Falken FK-453's who are known to be a smaller tyre, as the sidewalls don't really go straight up as with e.g. a Michelin PS

Oh yeah, I'm all around under high load. and I have KW V1 lowering (about -5cm)

Thanks. Seems like my setup should also fit, then.

Hi guys!
I have a set of 17" 157 style wheels with et34 and 225/45/17 RS3 hankooks. On the road it seems to be no problem with the clearence. But on a track, sidewalls were rubbing the wheel arches. Now I'm running et40 wheels with 235/45/17 and it seems pretty good. By the way i have m sport suspension. Both wheels are 8 inch wide.

[ovekvam]

Thanks. Then I should be safe with my setup!

Hi all, I really need help here.
I'm buying a F20 118i(non M sport kit), and will come with 16" and ET40 wheels.
I want to put Beyern Multi 18" wheels, but I'm not sure if the fitment is possible:

Front: 18X8.5 ET40 with 225/40-18 or 235/40-18
Rear: 18X9.5 ET45 with 255/35-18

Few questions:

1- In the front 225 tires with 8.5 inch will look stretched? I don't like stretched look, but I´ve afraid that 235 will rubbing.

2- In the rear is worst, 9.5 I think is too much and with 255 will rubbing inside or outside? Remembering the offset is high, ET45.
I can buy for rear the same as the front, 8.5 width, but I prefer staggered, my actual E81 have M Sport kit and factory staggered wheels.

What do you think about this unusual set fitment?
I´m from Brazil and I need to import from US this wheels, if eventually didn't fit, I couldn't change it.
Other information, I will not lower the car.

Thanks in advance.
Regards,
Fabio

I have 225/45-17 (Michelin Pilot Sport 3) on 8" BBS wheels, and they look slightly stretched.

[CmteFabio]

A little stretched is not a problem, the real problem to tell the truth is the ET40, I have doubt that fits, and the 9.5 inch rear wheels with ET45 too.
Making a research today, I found a store in UK that sells Beyern:

http://www.rimstyle.com/alloywheels/...ulti&year=2013

I made this because in Europe sites have F20 beyond the cars application, in US doesn't exist.
For this site, when we select a F20 and 18 staggered set that I looking for, they send together a 3mm spacer for rear wheels to better fit, maybe my doubt was answered here, if the site was right, I need a pair of 3mm spacers too.

Thank you, if somebody knows something more about this set and could help I will appreciate very much, is hard to find informations about the wheel fitment in F20.

[ovekvam]

I recommend looking at the wheel sets directly from BMW, what offset they have.
You find them in the online ETK:

[CmteFabio]

So, this is the problem....lol
Original size and offset are:

Front: 18 X 7.5 ET45
Rear: 18 X 8 ET54

Pretty different I think.

Looking for some help. Brought some wheels for winter and didn’t check the ET (my bad), so have a staggered set of Fronts 7.5Jx18 ET49 & backs 8.5Jx18 ET52 and putting ContiWinterContact TS 830 P 225/40R18 92 V RUN ON FLAT Tyres on them. I believe the backs are OK.
Anyone know if the fronts will fit and/or damage anything?

[ovekvam]

If the wheels get too close to the front struts, you could add 10 mm hub-centric spacers.

I'm also trying to get the best fit wheels, found a very useful link where all the variables can be seen in a graphical way.
