I'm Looking at m5 Wheels that have 235 45 17 on Front (8J)
255 40 17 on rears..(9J)
will these tyres Cause a problem on standed e34 ?

The M5 uses ET10 offset and the usual 5 series uses ET20. This means that the wheel will become closer to suspension components and the lip of the arch. IIRC there are no body differences on the two models?

You may find that the lip of the arch needs rolling. Apart from that I don't think there will be any issues:thumbsup
