It's definitely a truck issue and not a person to person issue. Last spring when my transmission in my 2006 was out of commission, I ended up using my triple A coverage to have it towed off the mountain to the transmission shop that ended up doing my rebuild. Triple A gave me a complimentary rental for the time my truck was down the mountain which was awesome. They put me in an early 2015 build SWB SLT Yukon, riding on SLT 18s. In the less than 10 minutes it took on the freeway to get to the bottom of the mountain, both my mom and I noticed major issues. It was terrible. Fortunately once we were well under highway speeds going up the mountain, the pressure was gone and I didn't drive that fast again while I had it. On the flip side my best friends parents have a mid year build 2015 escalade esv on factory 22s. Even when it was on Oem Bridgestone duelers it drove amazingly. I went on several road trips with them that I was invited along on, and there were zero issues whatsoever. No buffeting at why speeds, or odd noises or shakes. I don't know what causes it either, but it's definetly flaws in the truck. Been in several other gems as well and haven't noticed issues.
