Me and a coworker just picked up 2 new 2014 z71 LT's with the 18" wheels. While test driving his, the dealer mentioned the vibration was spots in the tires from sitting and wood go away quickly. I picked mine up today and it also has this vibration. This is very annoying for a new truck. Did a quick search and found this topic. Obviously not "flat spots" .
