Differentials are so cheap on these cars I would just swap one in if you think that’s the culprit. I’ve bought 2 differentials in great shape off eBay for like $200 delivered so far. And it’s an easy swap takes maybe 2 hours tops.

Also maybe the tires are bad have you tried rotating the tires to see if the vibration moves?

Seems to me it needs to be either driveline (driveshaft out of balance, guibo, or differential) or tire issues since you said it was parked right after new tires. Presumably the vibration started around when new tires installed.

Also if it coincides with engine rpm more than wheel speed have a look into the flywheel leaking. Research that on google.
