I know someone mentioned these tires a while ago in another thread- but they are now cheap enough that even I was interested...
NC State Surplus Property office on Hwy 54 (Chapel Hill Rd) just off I-40 in Raleigh has a bunch of new and (barely) used 225/60R16 snow tires for sale.
IIRC, they were Goodyear Winterforce tires. The used ones I saw looked to be barely used, and they were mounted on black steel wheels- I don't know what bolt pattern, but I think it's safe to assume they were either Crown Vics, Impalas or Chargers. The used ones were studded- they have small steel studs imbedded in the tread, but I *think* the new ones were studless.
Price was $50 for 4 of the used ones (tires/wheels) or $200 for 4 of the new ones (bare tires only).
They had a bunch of them, probably 8-10 sets of each, when I was there this afternoon.
Seriously thinking of buying a set of these for my BMW 528iT in case we see some snow next winter.........
