P225 / 60 R18. Passenger rear tire blew out driving at highway speeds (75-80 mph). The car swerved back and forth across lanes almost into the median and then to the shoulder a couple of times and almost flipped before I was able to pull to the shoulder and stop. Another driver stopped to make sure I was ok and said he also thought I was going to flip more than once. I did not notice any warning lights prior to the incident. There were a couple of times prior to the failure that it felt like the car was swerving slightly - I thought possibly due to wind or different texture of the road surface, then the tire blew. The entire inside wall of the tire is separated from the tread. The dealer has not inspected the tire yet. I am ordering a set of new tires - I don't trust these and never want to go through that again.
