I sold my 2012 E70 X5 recently and have a set of 18" rims and tires (86077) Blizzaks with very little tread wear as I haven't swapped them out in a good 4-5 years. They've been sitting in their tire duffels w/felt in pristine condition. They also have their own BMW TPMS valves as well if I recall (will double check), and center cap as well.

I also have an OEM trunk mat, and also an OEM BMW ashtray cup holder as well.

Make me a reasonable offer on them as they're taking up space in my garage. I will try to get some pics as well!
