Hi everyone. I'm a new '15 F34 owner and I am looking at using my stock 400M wheels / tires for winter. I'm overall pretty happy with the GT, but the square wheel setup is not very sporty.
I likely won't do anything with wheels until next spring. I've been browsing lots of forum threads, sites, etc. looking at everyone's F34 setups. I really like a lot of what I see.
Though I live in Michigan and keeping to 18" diameter would be ideal, more importantly I want to stick with a setup that maximizes rear tire width (purely aesthetic) and with an offset that would work with everyday camber at stock or slightly lowered ride height. I say purely aesthetic b/c until I run out of warranty and add power, or start running laps, the purpose will be to look sportier and lower my mpg.
So, in browsing around, I found an interesting OE offering that 1 site suggested might fit but I've seen no pictures:
BMW 310M 20" wheels (for the X3/X4)
Front wheels: 20x8.5" ET38 part #: BMW 36116787582
Rear wheels: 20x10" ET51 part #: BMW 36116787583
Tires:
On an X3 I've seen:
Front: 245/40R20 99Y XL +.7" Diam, +2.6%
Rear: 275/35R20 102Y XL +.8" Diam, +3.0%
This was an xdrive, so I assume ok with all abs/stability systems?
I was thinking to keep closer to stock diameter:
Front: 245/35 -.1" or -.4%
Rear: 285/30 -.2" or -.7%
20" wheels, even in summer, scare me a bit on Michigan roads. But, these wheels seem to be available and they are interesting to me.
I like the ET51 offset in the rear. I think they should tuck well. Other 10" rims with lower offset seem to be very close to the lip at ride height anyway, and if too far inboard, a spacer could be utilized.
If anyone has any information or experience or pictures of this setup I'd like to see them.
Thanks,
PJ Gross
