Tire Tread/belt problems of the 2001 Chevrolet Blazer

Tread separation on uniroyal laredo p235/70r15 all season awr tire caused over $2,000 damage to SUV and a messed up vacation. Canister was just hanging after the failure. (canister bracket was badly damaged and hose from gas tank was disconnected. ) the damage could have been very hazardous if a fire started.

Uniroyal tires have separation between the treads. The area between the treads looks like it is dry-rotted.

This problem first occurred at about 4600 miles. I took the tire to have it repaired at the tire shop I use. They told me it had some belt separation. I then went to the dealership where I had purchased the vehicle and was told by the service manager to take it to goodyear. I took it to goodyear and they told me that since my spare tire was already on that I should keep it on and that the tire only needed a flat repair. In September 2001 I started to notice a slight thumping noise coming from my vehicle I took it back to the dealership in October 2001 they replaced a front wheel bearing and the rear differential but still the thump. They told me it was a flat spot on the tire and that I had two bad tires and needed to go back to goodyear. The dealership told me that the other tire was bad too, not what goodyear told me approx. 8 months earlier. I am being told these tire problems are caused by my driving. I know this is not the case, I had a Blazer 3 yrs prior to this one with a different brand of tires and not once did I have any problems. (tiresize: p235/70r15).
