My first flat happened as i was pulling off the highway near my school. I got a piece of metal that is about 5inches long and 2inches wide all the way in my tire. On that same turn three other students blew out the back left tire just as I did. A week later i got a nail in my back right. The left tire was unplugable but the right they were able to get plugged. Luckly I had tire insurance so i got another tire for cheap.
