The interesting thing is I also have the Nitto Motivos that others have mentioned here too. They have about 10,000 miles on them. I really think my vibration is a tire issue because the vibration really started after the car sat for about 3 weeks. The tires must have flat-spotted from the car sitting and I don't think the tires have recovered from that since then. I never hit a curb, pothole, or anything like that. I check my tire pressure often too.
I've never been impressed with the Motivos anyways. I remember the car swaying more in turns after I removed the Pirellis and installed the Motivos. Tire pressure was same. The sidewall stiffness is noticeably less on the Motivos (probably because they're an all-season tire compared to the Pirelli's Summer performance status).
The one time I had an impossible to fix vibration (no improvement when road force balanced) it turned out to be a defective tire. Flat spotting is not a thing on modern tires that are made right. BTW, where were your Nitto tires made? I am trying to stay away from Chinese made tires because Chinese manufacturers lie, cheat, and steal. Right now my Camaro has BFGs made in the USA.
