Bought a new '24 Dually a month and a half ago while traveling through Atlanta. On the way back to Minnesota I noticed some tire vibrations and brought it to my local dealer. Truck had about 1500 miles at that point. They found 3 Nexen tires that they were unable to balance within specs and submitted warranty claims with RAM. That was back on April 8th. I've check back with the dealer multiple times, but they said its still waiting some kind of final approval. Is there something different about tire warranty's vs other parts?
