I'm selling the two OEM front tires from my 2011 Z4 35is. I swapped them out at about 1400 miles, and they were never driven hard or tracked. Almost brand new. Never used them again, and now I no longer have that car. Dealer wanted the OEM rears back when I handed in the lease, but didn't mention the fronts...
EDIT: Price reduced: $150 for both tires.
