NHTSA Complaint #11534012 — 2020 RAM 3500

While driving at 70 mph on I-75 July 1 2023, roads where dry, temp outside was 88 degrees, speed control set, my 2020 Ram 3500 diesel, 4X4 Mega cab pick-up began to shake violently, the steering wheel was trembling side to side ! I took the truck off cruise control and griped the steering wheel, traffic was heavy that day so it took about 1/4 mile to slow down and pull safely to the shoulder with the hazard lights on and the truck in park I got out and started looking at what was going on in the front of the truck! I didn't take long before I spotted a large egg shaped raised bump on the drivers side front tire! It was checked for air pressure before my trip and registered 80 PSI with a air gauge! I checked the passenger side tire and it was normal, ( No egg shape). I had the local tire shop remove the spare and swap it with the Drivers side lumpy tire. I had not even traveled 10 miles from the tire store when the steering wheel started to shake violently again, this time I took it right back to the tire store and thought that it might not have been balanced or threw a weight maybe, as the manager/ owner and I inspected the tire the drivers side was fine, we walked to the passenger side and we both saw a Hugh outward protruding bump on the center top of the tire running at an angle from front to back! He told me that it must be delaminating, that he couldn't be sure until he demounted it. I was out of spares, out of town and out of luck. I paid the man to mount 2 new Firestones and I would take it up with my dealer when they Opened on the following Monday! As I proceeded to Thayer Dodge, Chrysler, Jeep in Bowling Green Ohio, I felt the back of the passenger side of the truck begin to hop, the slower I drove the worse it became. Pulled into the dealer lot and left it running in park to cool the turbo down as I talked to the service manager, service manager asked to see the tires that where taken off, she saw the bubbles on the insides of both, told me to call NEXEM
