Maintenance/Repairs

Hi, I need serious help. I have a 2013 Subaru Outback that since I bought it, has had a rhythmic humming noise/vibration when at highway speeds (55-70). Sounds like a hum, hum, hum once per second. Vibration doesn’t shake the wheel, but you can feel it in the floorboards. Rhythm gets faster when driving around a curve to the left, quieter when curving to the right. I’ve taken it to several shops (including a Subaru dealer) and was told it is not the wheel bearings and those are fine. They told me it was because the tires were cupped and new tires would fix it, but getting new tires did not fix the noise. Firestone said my alignment was good when they mounted my new tires too, so I don’t think it’s an alignment issue. Suspension feels fine, not crazy bouncy or anything.
