When I first bought my LJ about 2.5 years ago I had a bad vibration. It had chrome 16s on it and I wanted to move to 15s and go black so I bought some cheap steelies and some 31s and gave the tires and wheels to someone else. They in turn installed them on their TJ and they developed the same balance issue.
Now I work at a Toyota dealership so I had the ability to balance the original tire wheel set up but could not get a satisfactory ride with the original setup and I checked the tire wheel and forced matched but could not fix.
I fixed mine with new tires and wheels....
Just food for thought
I literally just saw my 2014 wrangler rims “flake off” the weights of one rim in my driveway when it fell over as I took it off my TJ (doing front suspension now)
So yeah wheel balancing is obviously a point of contention to be concerned with. Never take anything for granted
