general problems of the 2008 Chevrolet Silverado 2500

The contact owns a 2008 Chevrolet Silverado 2500 equipped with bridgestone tires, tire line: dueler a/t revo 3, tire size: lt265/75/r16, dot number: 9bw8 re3. The contact stated that the tires were purchased in California. The vehicle was driven back home to idaho, where the tpms alarm sounded. The vehicle was taken to the dealer for an oil change and the vehicle was inspected, and the contact was informed that the rear tire was flagged and was informed that the tire needed to be removed. The tire was not removed. The contact notified the manufacturer, and the contact was referred to a firestone location for an inspection. The manufacturer was informed that there were no firestone locations nearby. The manufacturer approved the contact to take the vehicle to a commercial tire shop for an inspection. The vehicle was taken to the commercial tire shop, and the contact was informed that all four tires were dangerous and needed to be replaced. The tread on the rear passenger’s tire was worn, the sidewalls of another tire were falling apart, and the tread and sidewalls on the other tires were separating. All four tires were replaced. The manufacturer was notified that the tires were replaced, and a claim was filed. The vehicle failure mileage was 169,508.

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.
