I have a set, but shipping could be expensive from NH. Someone local that could pick them up would be preferred. They probably don't have much more than 8K miles on them, but are original from 2014, so at about the recommended service life. But, if you look at the price of the wheel, it's more than BMW charges for the entire winter tire ready to mount, or at least did back when. Originally, retail was about $2K for a set. I'd take $1000 plus shipping.
2014 i3 BEV, 2021 X5 45e
(The i3 will be sold soon, <17K-miles, interested?)
