A tire iron is a tool used for working on the tires of a car.


The tire iron originally belonged to the Hill Valley Police Department, and was located in a toolbox on a Paddy Wagon. When Marty McFly altered 1931's history, he used it to help Emmett Brown escape from the paddy wagon, which had been hijacked by Kid Tannen, and then it was dropped onto the road.

The tire iron was lost for over 50 years, until being found by Jennifer Parker in 1986G, when an older Marty used it to break the impaired DeLorean's window to aid his escape.
