Ron's Used tires in Manassas, bought 4 used michilen 215/50/17 with a good amount of tread left for $120, guy gave me a discount cause business was slow. They mount and balance too for like $50 but that includes the tires. I just bought the tires cause I work at a car dealership and did the work myself. One of the tires I think has a slow leak cause my car pulled to the right and so I rotated the tires to the rear and it stopped. But what can I say, thats what you get when you buy used....
