I ended up calling around to junk yards for wrecked Chargers, 300s, Magnums and located a spare tire set that way. I drive my car a lot and wanted to have a spare tire.
Welcome aboard from Columbus OH by the way! One guy in the Cleveland area has a white Kowalski Special Edition 1-10 '11 SRT8 and he came down to a Meet N Greet we had earlier in the month. I don't know anyone else with an '11 Challenger in town let alone an IE 392.
