I have been trying to resolve this matter with nitto and have had the tires inspected by one of there distributors at their request. It was determined that the tire separation that is occurring appears to be a manufacturing defect according to the inspector. This is the fourth tire from this same manufacturer to fall apart and at approx 18000 miles with this set. It is a huge concern as they show no signs of wear or defect until they are about to fail. Fortunately, I have become an expert at feeling the irregularities while driving and have now started inspecting the tires immediately before my life is threatened. This is a real problem that I was hoping to get the tires, I saved two of them, back to nitto for examination. They initially seemed very interested after hearing the news from their inspector, but my attempts to contact them have been ignored and they have failed to follow up as promised. I was forced to replace one tire already due to my location away from home at time of incident and while traveling home I felt the other tire start to go and yes this was also inspected. I will now replace all of my tires yet again (with a different manufacturer this time) for simple fear of failure and injury or death. I felt at minimum you should be made aware of this situation in case others have been injured due to their faulty products. It bothers me greatly that they would not want to have these returned for evaluation. I wasn't requesting any warranty or compensation, so it's not about money for me.

Firestone tire P245/70R17 108S M+ S destination le for your information while driving the inside lane of I-20 here in Alabama August 23, 2014 at a speed of approximately 65 miles an hour when my right front tire blew. Fortunately I was able to maintain control of the vehicle and get off the interstate. The tire blew out just below the thread, outside wall. Hole is approximately the sizes of a twenty five cent piece. I had an experience tire professional look at the tire; he said that the tire was defective because of the way it blew. The other three tires on this vehicle are firestones identical to this one. I am worried about the safety of driving the auto with these tires? the tire is on a 2008 Chevy Silverado pickup that is driven for pleasure. (not a work truck) less that 10,000 miles a year. All four original tires were replaced with firestones P245/70R17 108S. I would estimate these tires to have less than 20,000 miles on them.

Right front tire blew out, when we went to have them replaced we noticed a bump in all four tires, upon calling general we were told to take the truck to sears (authorized dealer) to look over the tires, sears confirmed that there was a belt separation in all four tires. We were told by general tires they would give us a 60% replacement on one tire. We then called General Motors to report the problem they told us we needed to take the truck to the dealer where the truck was purchased. After leaving the truck all day the service manager reported that the replaced tire was not an original tire (it was the one we had fixed due to blow out) and that it should not be warranted. At this time nothing has been done to fix any of the tires. We were told by a representative at General Motors that there were other reports of problems with these tires. A second representative denied that other problems has been reported. There is definitely a manufacturers defect in all four tires.
