Tire Sidewall problems of the 2003 Chevrolet Suburban

I bought my Suburban with goodyear tracker ii tires on it from the dealer in Dec 06. In April 07 a tire was flat. It had a small slice in the sidewall of the tire between the grooves. Nothing had touched or scraped against the tire to cause it. I bought another one from walmart as they are only ones able to get and sell them. I had taken the wheels off for the summer and put them back on in sept 07. In March 08 on this new tire, it had a leak in the grooved section of the side wall near the tread. Again nothing punctured it or scraped it. Because I couldn't change the tire at the time I had to put a plug in it to get home. These are very poorly made and should not be allowed. I have never had any other tires get small slices in the sidewall. I could understand if I hit a pothole, curb, nail, something. But the first tire was 3" above the ground and this one was about 1" above the ground. I have about 5,000 miles on this tire with alot of tread left that is now garbage.

While driving on the garden state parkway in NJ (mile marker 133. 6), the driver's side rear tire blew-out while traveling at approximately 65 mph.

2003 Chevrolet k2500 Suburban with firestone steeltex lt245/75r16 tires. On Friday June 10, 2005 the right front tire suddendly lost pressure while traveling on i95 at 65 mph, at ambient temperature of 94 degrees: however, I noticed the loss of pressure before the tire went completely flat and was able to safely pull to the shoulder. Upon inspection I found no punctures. The inside side wall had a 1-1/2" crack where the tire began to separate. The tire had 68781 miles of tread wear with approximately another 10000 miles of tread life left. The tires have been rotated and tire pressure checked on a regular basis that is evidenced by the long life of the tire. The tire is still in my possession.

While driving at approximately 45 mph along texas hiway 242, a relatively new hiway with uniform road surface in good condition (north of houston). Vehicle is a 2003 Chevrolet Suburban. A loud buzzing sound was heard similar to that produced by the ribbed edge-of-roadway warning strip found on some hiways. I at first thought the character of the road surface had changed; then, a few seconds later, the passenger side rear tire collapsed suddenly. Upon stopping on the shoulder I found that the tire tread surface had separated from the sidewall on the outside of the tire and around the entire circumference of the tire just at the manufacturing seam where these two components are joined. Five radial rips had also occurred in the sidewall leading from about the middle of the sidewall to the separated tread/sidewall seam. The tires were standard equipment on the vehicle (purchased in may 2003) and have been driven approximately 25,500 miles. The tread is still very deep. The tires are firestone wilderness le p265/70r16 111s type.

Tires had 39 psi at the time of blowout. No vibration was noticed prior to blow out. No visible bulging in the tires. Contact stated that no other damage was present on tire, besides a verticle split through the tire from the rim through the tread. No problems with tires before and no other tires were damaged. Right rear tire.
