Thats a pretty good price if they are in good shape! The tires alone will sell for approx. $1000 for the four of them new, so you are getting a good deal. Just make sure you see all 4 wheels to make sure they don't have any curb marks on them, and make sure they come with the Tire Pressure Sensors in them. After you get them mounted you can take it to your dealer and they will re-flash the speedometer for you to match the tire size and make sure the sensors are activated. They will usually do that at no charge for you. Take the plunge, at that price if they are in good shape you can't go wrong!
