I have 4x original 19in wheels (start spoke) style 212 Silver finish
with MICHELIN RFT tires, size 255/50 R19
5 months old (10,000 KM)
filled with nitrogen by BMW dealer and ready to go
EXCELLENT condition

If you are looking for upgrade or winter tire, I think this is a great opportunity for X5 and X6.
Asking $1,790 (OBO)+ shipping
