I have one of the 2016 Silverados that have a vibration at highway speed boardwalk Chevrolet just blew me off and told me it was because I changed the tires when I tried to explain to the guy that tires don't last forever my truck has almost 27,000 miles that's pretty good for the crappy factory tires they put on... long story short I should have bought a Ford
