So it looks like the BMW black steel 18” compact spare wheel ( part # 36-11-6-768-861 for the X5 and X6) should work on the 1M (and M3) with the appropriate tire (ie Maxxis 155/70-18 112M part # TP 10676000 giving a diameter of 26.54”or several of the other suggested choices). Thanks Tom303 and flzrider for the link to this information!

I have a couple of questions related to using this wheel on our 1Ms:-

1) Is the bolt/stud hole size on this wheel larger that what is on the 1M wheels? ie ours are sized to take a stud 12mm in diameter.

2) If the hole size on the steel wheel is larger is the purpose of the “centering ring” to ensure that the smaller diameter 1M (M3) bolt/studs will center precisely in the steel wheel holes? – Or is there another purpose for the ring?

3) Will our 1M bolts/studs be useable with the steel wheel or will a different set of bolts/studs be required? ie same diameter but different length?

Thanks for your help - pete
Right - just had the 18" steel (with 135/80 x 18 Continental s/s tyre). Fits fine with standard wheelbolts (M12) - the standard conical profile bolt fits fine in the hole. Also, it does not require the plastic centre spacer - this is just for ease of fitting rather than for anything else. Think about all those ancient VW Beetles with those massive holes in the centre of the wheel!
