(4) brand-new Pirelli Sottozero 225/50R17 run-flat winter tires.
Tires even still have the stickers on them - I ordered last year for our BMW X1, but sold vehicle in the meantime before these even were mounted.
Currently out-of-stock at Tire Rack, but once in-stock would be $1000.
These are great performance winter tires: balance lower wear during weekday driving with great traction for the snow in Tahoe.
