dunno if it's the same issue but I have a lifted 2015 Ram 1500... got new tires (load e rated 35X12.50 general grabbers) and started to develop a pretty bad vibration that was annoying the crap out of me. Many trips to Dodge... many rotations/balancing and replaced shocks/spacers with coil overs, rear shocks.. about every bushing and upper a arms (BDS), and still no improvement ...
I finally took to a four-wheel drive shop and they rebalanced my tires with beads instead of weights... solved it for 10 bucks a tire. Obviously, this was the last step in the process for me, and all the changes i did prior were solid and no regrets since I plan to keep the truck, but I wish I had started with the beads. Could even do it at home if you have a valve stem tool and an air compressor.
good luck!
