I just had LT285/60r20 General Grabber AT/X's installed and now notice a horrible shake or vibration in rear during acceleration. Could this be from improper balance or be from going to a larger tire?
Thanks in advance!

If it’s at or over a certain speed I would have them rebalanced. I just installed these in 275/70R18. The least amount of weight was 1.5oz on one tire. The most was 2.5oz. That’s pretty good IMO for a 55lb tire. I’ve taken mine to 70MPH with no issues. Just noticed a little more hum vs. the stock SR-A.
