Subaru Problems? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Did the noise start as soon as the tires were installed?
The hearing aid can pick up more odd decibel noises than most others can hear. You may want a unbiased person to ride and see if they can hear it. I would really like to say its the tire tread design to blame for this noise since it seems to have started then. One thing you can do is get the car to the speed where it is worst and swerve aggressive but safe to see if side load on the tire effects it. If so then it could be a wheel bearing your hearing. So far I do not believe its the CVT doing this but something else in the drive train could be like a carrier bearing.
