Had a PUP that had a blow-out at about 65mph. Didn't hear or feel it happen. I just happened to look in the sideview mirror and see the PUP bobbing up and down a bit more on the left side than the right. Then I started to see pieces of rubber flying. Changed it on the side of the highway, went to the nearest Farm & Fleet and bought a new rim/tire combo, then continued on our way. Wasn't too bad an experience. Like someone else said, the scariest part was changing the flat on the drivers' side on the side of the highway with semi's flying by at 70mph....
