Tire Blowout problems of the 2011 Toyota Prius

On October 18,2012 I was driving my 2011 Prius 2 on a 2 lane highway at 55 mph when the drivers side rear yokohama tire blew out on the sidewall. I swerved in to the left lane twice before leaving the road, snapping off a utility pole, going down a revine and rolling over end for end and side to side. I ended up in the middle of the back seat on my stomach facing the rear of the car. The drivers seat was broken back and my seatbelt was still on. I was in in the hospital for a month following back surgery. I had 3 cracked vertibre and one cracked rib as well as many bruises. Needless to say the car was totaled and I am still recovering 3. 5 months later.

I was driving on the 101 n freeway at about 55 mph and I heard a loud popping noise. I had never had a tire blow before so I didn't even realize what was happening until I heard the flat tire. Luckily it was my left rear tire so I was not injured and I was able to safely make my way across the freeway onto the right hand side of the freeway where I called aaa to come and change it to my spare. I called Toyota, they said they had nothing to do with the tires and could not help me and I would have to make a complaint to yokohama, the tire company. I called the tire company, they told me to have it inspected and it was found that it was a road condition that led to the tire damage and therefore it was not under warranty. The exact same incident occurred again on 01/15/2013, this time I was going 65 mph on the 101 s freeway. My rear right tire blew out and I had to get across traffic where I got off the freeway and was able to call for help. My concern is not whether the tire company will be able to foot the cost, but the fact that my tires will blow out when I'm driving under or about the speed limit for a road condition that everyone else manages to drive on with no problems. I reported both incidents with Toyota and yokohama.
