OK, so I just got word back from the dealer on my whole wheel/tire setup - I wanted a second opinion on what my trusted mechanic had told me. As it turns out, he was ABSOLUTELY right about these d*mn cheap @ss tires from China and the vibrations I've been feeling. They are out of true and made of an inferior rubber compound, creating a severe cupping pattern on the tread. Thus, this is causing what feels like a balancing issue, wheel bearing issue or even a strut/shock issue. So, I'm going to live with them for the time being (it's not overly severe - but noticeable), and start looking for a very high quality tire for the near future. Good to know that none of this is related to actual mechanical issues. Note to anyone out there looking for new tires, stay the hell away from these POS Delinte tires - they are awful.
I'm thinking about picking up the yokohama parada spec-x series tires in the 285/25r22 variety - hoping these will not be problematic based on the reviews I've read.
