Tire Bubble problems of the 2003 Dodge Durango

I have a 2003 Dodge Durango. In Dec. 2006 the original tires walls started to separate from the tread to the point that it was a complete ring around the tire showing the treads. I had to pay the difference of tread wear to replace the tires after arguing with a goodyear dealer. On Aug. 3 2007, I was riding on 495 doing the 65 mile speed limit when the tire started to bubble, smoke and then proceed to shred. I took the vehicle to a goodyear dealer who started to refuse to replace the tire at their cost because he said the replacement tire was replaced with the same recalled/defective tire. I now have 5 tires that are starting to have little blisters all over the wall of the tires. I am in no position to pay to replace these tires with another kind or brand. I want these tires replaced with something that is not going to kill us one day. Or give me the money to buy a different brand.
