Cabin Vibrations at highway speeds (70 mph+)

***Resolved. Thank you all for your responses on what the culprit may be. I was suspicious of the wheels being the issue, after removal, I measured them at the toyota hub bore of 95.1 mm, and couldn't find any hub ring, or even if it was possible to get a 2 mm hub centric ring made, so I found a set of bronco wildtrack take offs (+30 from google search, tires are falken at4 275/70/17) and they did the trick. Rides like a completely different truck. Thank you all again and appreciate this community!

I've bought hub rings as small .8 mm...
My Magnum wagon needed just 1mm rings to get the aftermarket wheels to run true...
