NHTSA Complaint #11547508 — 2020 CHEVROLET SILVERADO 3500

Tire size LT275 65 R20. Driving on Interstate Sunday September 24, 2023 the driver's side back tire blew out causing damage to the rim and side panel of the truck and bumper. We were pulling a 35 foot fifth wheel. We were able to successfully pull over to shoulder but had to wait over an hour for help. The blow out did do some damage to the fifth wheel also. Felt very unsafe until Georgia Champs arrived behind our camper. Our truck had about 16,000 miles on it and the tires. Last October the passenger side rear went flat (12,000 miles on the tires) and were able to pull over before a blowout. There we were stuck for about 3 hours on an interstate and had to change the tire ourselves because couldn't get someone out and felt unsafe waiting any longer.Both tires were on rear of truck and the blowout left over $6000 damage according to the estimate not including damage to the RV.We had no warning alert on the truck and a Goodyear salesman said the tires were not defective. But, we did not run over any apparent road hazard. We felt unsafe and were lucky the blowout didn't cause us to lose control of the truck or RV. Seems hard to believe this can happen twice in less than a year with pretty new tires. We always inspect the tires and make sure the tires are properly inflated according to the truck specifications.
