I've got 4 original tires off a M3. They are the Continental ContiSportContacts. They are right off of a new M3 and have no more than 500 miles on them. They are in perfect condition. No Burnouts or hard corners. Front: 225/40ZR-19 Rear: 255/35ZR-19. Tire rack sells the fronts for 203 and the rears for 233. I'll sell the them for 500 (OBO.) for the set. Buyer pays shipping.
