NHTSA Complaint #11579606 — 2014 CHEVROLET SILVERADO 2500

LT295/65R20 Two Nitto Grappler G2 which were on the rear of my truck, the internal belts of the tire have separated, causing a buckle of the tire. The separation caused a bouncing rough ride. This is a safety issue when riding the vehicle and I believe eventually it would have blown. The two tires were replaced by Discount Tire under my extended warranty that I purchased with the tires. I did contact Nitto Tire and attempted to have them replace the remaining front tires, I believe they will be separating very soon. Nitto refused to replace the tires, due to the tires being over 5 years old. The tires are not worn and have 11/32’s thread. I believe Nitto has a problem with the tires separating and should be addressed.
