I bought a "01" 2500HD Silverado to replace the 1990 half ton Jimmy I used to pull my camper because we planned to upgrade to a fifth wheel. The truck is only driven in the summer months, has never seen snow, used almost only for pulling our camper, and had only 28, 328 miles on the original factory installed tires (Firestone)which I always check the tire pressure before a trip. On 8/27/10 while pulling our camper we were going 65 mph when I started to feel a vibration from the rear of the truck, as I was slowing down the tread belt came off the tire. The tire did not deflate so I easily made it to the shoulder of the road. When I got the truck stopped I checked the damage to my truck and the other 3 tires, I found that the other tires showed tears that looked like they also were going to lose the tread belt. We drove to the first tire store we could find and had all the tires replaced. When we returned home I contacted Firestone and told them what had happened. The lady I talked to said there was nothing they would do about my problem until I told her that they were the factory installed tires, I was then given a case number and a phone number to call. I was sent paper work to fill out which I did and they also wanted the tire which I had to send at my own cost ($46.00). In the end I received a letter from Bridgestone/Firestone that they would not pay for damage to my truck or cover any of the cost for my replacement tires, as my tire "exhibits conclusive evidence of over deflection". I had to find out what this meant so a quick look on the internet found "Tire deflection (the tread and sidewall flexing where the tread comes into contact with the road)". I have never run my tires under inflated or overloaded them. It also said that Firestone tires at ten years old should be replaced. My tires were manufactured the 18th week of "2001", under their recommendation my tires had almost another year to go with plenty of tread left and only 28, 328 miles on them. I really do expect them to pay for the replacement tires, the cost of shipping the bad tire, and at least the $500.00 deductable to get my truck repaired.
