Need help! Thumping from rear left tire!

I have a 2001 Mustang Gt. She has about 112,000 miles. The issue I am having is a thumping noise. Almost like a flat but not quite as violent. It also increases/decreases with tire speed. It has brand new tires and rims. It doesn’t always make the noise sometimes it’s non-existent sometimes it’s non-stop. Do you guys think it could be wheel bearing/hubs or suspension related?

Thank you guys for the help,
Kyle

It’s kind of mushroomed out. We had to file it down the make the rim for up on it. However it has been working so far. None of the lug nuts have come loose. The only problem is that noise

Was the noise present prior to installing the new wheels?

Happens when going straight, when turning right or left, or just whenever it feels like?

The area the rim interfaces with the hub is critical.
If the hub face is not flat and true (no axial run-out), the rim will not set perpendicular to the axle center line.
The displacement is exaggerated out at the wheel edge creating a wobble as the wheel rolls.
You may need to replace the axle, which is really easier to do than you might imagine.
