I sent a set of tires to a California locale and it was about $45 a tire. They were a little smaller and lighter but also much farther away. That said, I would plan on $200. Even at that it will be a savings of at least $300. Tire rack was $1360 plus $75 to ship. Don't know how they get the shipping that cheap, maybe they just make up the difference in the price of the tire.
Either way if that sounds good to you I will check with UPS on tomorrow. Let me know.
