"I think he broke your tire ..."
Bison in Yellowstone National Park have been quite active this summer, and it seems as if the incidents are increasing. One of the more recent bison encounters involves a horn and a car tire.
With mating season in full swing, the males can get pretty aggressive, and that behavior was captured on camera. In the footage (below), the bison can be seen just to the right of a car before it then charges and headbutts the tire, ultimately popping it. The distinct sound of air being released from the punctured tire can be heard.
