Fair Oaks Chrysler Jeep Dodge Ram

I am a police officer out of North Carolina. I took time out of work and drove 5 hours to Virginia, to purchase a 2016 Jeep Grand Cherokee. On the drive back to North Carolina, I noticed that the vehicle was vibrating at 70 MPH. This vehicle currently has 829 miles, I took it to a local delearship reference the aforementioned issue. Well I was advised that the tires had flat spots from where it was sitting at the dealers lot for 6 months. Called Fairoaks back, they basically told me they were not going to replace the tires. Long story short I am going to buy four new tires on a brand new vehicle with 829 miles. Thanks Fairoaks Chrysler Jeep. Oh and I also contacted Chrysler, which met negative results
