2015 GMS 1500 4X4 Z71 - same vibration!!!!!!! brand new truck with 19 miles. I believe the tires are the main problem, going to ask dealer to change to Michelins, I'm sure they will try and make me pay the difference but we'll see. Bought a set of goodyears for my last truck and 4 out of 6 were so f&$ked they could not balance them.
also I have a friend of a friend thing that just started the lemon law with there 1500. not looking good for me fixing this vibration.
