Usually you can just call them and they will let you know if it's in stock or which store has them. If not in stock they will order them for you. They do not do oil changes.
They don't do oil changes. I called and asked if the tires I needed were in stock before I went in. I went down, paid for the tires, they took my keys, and I shopped while they changed them. They called me once they finished. As a bonus they fill the tires with nitrogen instead of regular air. It's part of the service. I don't think I'll ever get tires anywhere else.
Call or stop by the store. No oil changes.
