I've done well with used tires in crummy passenger commodity sizes like 195/65/15. I drive 10-15 year old economy cars and these same cars are getting junked due to rust, so I get their tires at the junkyard.
If I had something that took expensive tires, like a bro-truck, every bro out there would hold on to his stuff and demand top used dollar.
That said, my junkyard is "up to $20" now (making a great deal just good), CL is even worse, and I'm just now getting my third brand new set from DTD.
