I'm going to buy E90 bolt (36 13 6 781 150 M12x1.5) to compare it with mine F30 (36 13 6 781 151 M14x1.25)

[getman3d]

Bolts are really different: F30 - Left, E90 - Right. IMHO the rims are incompatible...

And what about the angle of the "cone" of the bolt? There can be free play of the rim...

Nice pic to show the differnet size of the M14x1.25 and M12x1.5 bolts.
At least the angle of the cone seems to be the same and the holes of the e90 wheels are large enough for the f30 bolts so I still think it should work.

I tend to agree- the angles look the same

I've measured it in Photoshop = 60 degrees. The same.

hi all

iam pretty sure that 397 whells will work on E90 / E91

they are Et 34

My concern is about 400M the rear ones are ET 47 !!!!!

what do you think ??

Wheels: Wheel 1 Wheel 2
Wheel size 18x8.5 ET 37 18x8 ET 47
BackSpace 157 mm (6.2'') 161 mm (6.3'')
3 mm (0.1'') deeper.
Rim Lip 17 mm (0.7'') wider
Typical Weight ~ 28 lbs / 13 kg ~ 26 lbs / 12 kg
Tires: Tire 1 Tire 2
Tire size 255/40-18 225/45-18
Section width 255 mm (10'') 225 mm (8.9'')
Sidewall 102 mm (4'') 101 mm (4'')
Tire diameter 661 mm (26'') 659 mm (25.9'')
2 mm (0.3%) shorter.
Rim sizes 18x7.5 to 18x9.5 18x6.5 to 18x8.5
Circumference 2076 mm (81.7'') 2069 mm (81.5'')
Revs per mile 775.4 777.7
Speedometer Assuming that this is OEM tire and speedometer readings are correct >>> When speedometer reads 60mph (96.6km/h) actual speed will be 59.8mph (96.3km/h): 0.3% slower.
Typical Weight ~ 25 lbs / 11 kg ~ 23 lbs / 10 kg
Wheel+Tire Weight ~ 53 lbs / 24 kg ~ 49 lbs / 22 kg
Clearance: Package 1 Package 2
Suspension Assuming that this is OEM wheel/tire and there is no any problems with clearance on both sides >>> 100% clear (leaves even more room than OEM)
Fenders 100% clear (leaves even more room than OEM)
Wheelwells The same.

Those ET47 wheels will fit on e90, but will look really tucked, so spacers are kinda needed.

Yes, cone angle (taper) is the same on both 12 & 14mm studs. Have physically measured the angle and placed 14mm studs in each rim type.

Glad to see some traffic starting to pick up on F30 post. This thread seems the most comprehensive on what I expect to be an ongoing conversation (maybe worth making it a Sticky?).

I am currently running 189s as my winter set-up for my e90. I will be ordering an F30 soon (likely Msport/RWD, possibly Adaptive M suspension). From what I have read on this thread it sounds like:

1. I will have no problem mounting the 189s on an F30, but I will have to use the F30 bolts.

2. The front will fit perfectly fine but the rears will be a bit pushed out.

(Please correct me if I am wrong on those!)

3. My question is, with the lower profile tires on the 189s, I suppose there will be more of a wheel well gap, but is there any other negative consequence of having the "incorrect" profile ratio? Incorrect speedometer reading? I guess logically you have less rubber so could there be increased risk of damaging the rims on a pothole or bottoming out in general? Not that I had planned on it but I assume dropping it would increase any of these possible issues. Does anyone know if the M adaptive suspension is any lower than the standard Msport?

Appreciate any input!!

For all those interested, I've replaced my 397's with my old 156 style alloys for winter on my F30.

They fitted with no issues, albeit there's not alot of room round the calliper.
