Tire Bubble problems of the 2008 Jeep Patriot

We have bought a new vehicle on March 20th, 2010. We was told that the tires and everything on the vehicle was fine. On may 17th we took the vehicle in to get one of the tires changed and found out the other three of the tires have the same problem. The wires in the tires ae separating, which are causing the tires to bubble. In the end it's causing separation throughout the tires.
