Done that too had a bad shimmy starting at 55mph and would shake the wheel a couple inches to each side. Had to take each wheel off and clean the rims of all the mud, and grass, and rocks Now she drives smooth as silk
Haha I was the complete opposite, I thought I had mud caked on my wheels on my old z71 but I actually broke my cv axle. Donuts in 4wd is not smart. I trashed that truck. Lol
Every 6-7K we have them rotated and rebalanced, it's in our tire purchase package options. Supposed to make the tires wear evenly and last longer unless one's driving method is hard on tires.
