Default Humming when on accelerator

Hey all, I'm fairly new to this car, only had is for about 2 weeks, so sorry if this is normal. But I noticed that when driving I hear a strange humming noise, almost like snow tires on dry road. It's coming from the rear, and I can only hear it when I'm pressing on the gas, getting louder with speed. I thought it was my old run flats, but I swapped them out for brand new one's last week, I also changed the diff fluid, neither helped.

Any tips to finding the cause would be appreciated.

I was thinking it might be that, but wouldn't it always make the sound? It should be constantly running if I'm not mistaken.
