At least 30 spectators were injured Saturday afternoon when large chunks of debris, including a tire, sailed into the grandstands at Daytona International Speedway when a car flew into the fence on a frightening last-lap accident. Video from the area where debris showered the fans has surfaced.

This isn't confirmed, but in this video you can see a tire (or something that looks like a tire) in the seats near the guy who shot this video.

Caution: explicit language.
