Vibration

[Ecoram2017]

Hey guys I’m new to the ecodiesel forum.
I have a 2017 ecodiesel big horn.
I was running original tires and mags with 2.5” leveling kit.
I changed the tires to a 33” more agressive and LT TIRE. There was a slight vibrate going on and then it got worse with time. I thought maybe I bent a rim or something which I New I didn’t so I went out and bought some new mags from HD. In the mean time the dealer found some problems with my diff rebuilt it and balanced the drive shaft. I put on my new mags with my new tires and the vibration is still there. Also when I put a maxi trailer on it makes the vibration worse. Do you guys have any idea what can be causing this vibration. Now the dealer is giving me a hard time and is saying it’s the tires but when I got them balanced it didn’t take a lot of weights or look off to me.
Give me your opinions

Not sure what kind of tires you have, but I put some 35's on my last Ram (2500 6.4 Hemi) and they were off brand (Cheap Chinese). I had them balanced 4 times (even road force balance) before I finally figured out that they were pretty badly out of round. I ultimately had to get a new set. If I were you, I'd have them checked for run-out. If the tires aren't out of round, then have them road force balanced. Good luck!!
