I was driving alone at freeway speed of 65mph, when it felt like I had hit a strong wind, but the trees at the side of the road were not moving, so I started to pull over to the side of the freeway, when the tire blew out. The entire sidewall blew out of the tire. I have a photo of the tire. No one was injured but the rim is pretty torn up. (dot number: W2vfnna199 tiresize: P21565R159)
