Just outside Detroit, along the side of a I-94, sits a very big tire. In this episode of CuriosiD, a listener asks how the Uniroyal Giant Tire ended up there, and what it's like inside. Plus, did the it ever roll across the freeway? WDET's Jack Filbrandt goes the extra mile to get some answers. Have your own question about Detroit? Submit it at http://wdet.org/curious.
