Ive had this issue for a few months and it has been getting exponentially worse. At around 15mph, especially if I'm not accelerating very fast thru that mph range, I get an extremely loud and annoying vibration that reverberates throughout the entire cabin and makes everything else vibrate. Its coming from the rear of the car I think and is so intense it sounds almost like the tires are rubbing but I don't see any signs of that. I thought maybe wheel bearing but it doesn't intensify with speed, it's only at slow speeds. Sometimes it doesn't reverberate but simply sounds like a tire running the fender. I can't track it down. Weight in the car has no effect on it. Neither does braking.
I'm almost thinking this has to be the tires themselves. I've noticed when looking at them that it must have a hard and softer compound because every other tread block is higher or lower than the one next to it. So my assumption was that like a mud tire, those gaps and raised lugs are making bad vibrations and being that the tire is close to the fender it reverberates even worse.
Does anyone have any ideas to help me? This is driving me crazy. I've also checked the strut bolts and the sway looks fine.

If you think it's the rear tires, rotate them to the front.

All the tires are the same and fairly new. I think maybe that it's the tires in combination with them being close to the fenders in the rear

Rear tire damage is felt more strongly through the seats of the car, while front tire damage is indicated by steering wheel. Give 'em a rotation and see what happens. If it still feels like it's the rear, your wheels and tires are eliminated from the list of potential issues.
