FWIW Theres a place Tonys Tires at 9th & Oregon that sells & installs used tires. They generally have decent tread, usually the big places will have people come in and just purchase all 4 new tires, so 1 or 2 may be reusable. They'll then dispose of these to these type places or something.

You can get a great deal if ever your in a pinch.
