Small update on my issue, got new front tires and fixed the problem. Although the front left was the one making a noise, I drove over a monster pothole on the right side which instantly deflated it. So kind of worked out to replace both at the same time.
Car drives great and straight...
Has anyone had this problem at lower speeds?
My 2020 has a thumming / whirring sound at low speeds between 15 - 25 mph, but smooth and quiet on the highway. I have an appt with Toyota on Friday but not too confident they know what they're doing. Sounds like its coming from the front driver...
