I haven't figured out an exact price yet, BUT bearing in mind they cost £1113 to buy + extra to fit the tyres to the rims and balance them, coupled with the fact they are pretty much as new, I don't want to take a stupid loss on them as I will in all likelihood plough the money back into a set of 18" winters for the X3 - which are more expensive
Feel free to PM me with an offer and i'll consider it.
I can post more photos of the rims/tyres/tread if needed. They looked great on my 5 series.
