Rubbing noise from front left wheel
I recently changed the front left wheel bearing. So i dont think it's that. I know the noise is coming the front left tires/rim because, when the front left wheel was swapped to the right side, the noise went to the right as well. When the wheel was swapped back to the left, so did the noise. I just dont know what within the tire or rim could cause this noise. Wheel has been balanced and tire pressure checked.
My mechanic suggested the steel belt in the tire might have shifted. But i am skeptical with that answer. Can anyone help?? Thanks in advance!

Tires and rim - OEM

The tread and tire physically looks okay; no feathering or cupping, and the tread looks evenly worn out. However, prior to rebalancing my left wheel, the mechanic told me it was slightly off balance. After rebalancing, the noise went away, only to return the very next day. Now the noise comes and goes, it's not as consistent as before....

I think it is a delaminated tyre or something inside the tyre like a piece of TPMS sensor etc.
The fact that the noise moved with wheel location removes possibility of suspension drop links & castor bushes or wheel bearing. I would have been suspicious that the new wheel bearing had been overtightened or damaged at fitting.
Take a very good look at the rim for peripheral cracks & around the lug bolts. Ensure lug bolts are tight.
I think we have a tyre delamination/separation here. Time for a new tyre. If you jack up the car & unload the wheel & then spin it does the noise disappear?

When the car is on a jack and the wheel unloaded, the mechanic and I didn't notice any noise when spinning the brake disc....
You are probably right. It seems like another member in another benz forum experienced the same noise and it was fixed by replacing the tire.

If the tread separates it can also cause damage to your wheel well
Delamination is the process where the tyre through various possible reasons separates into its component parts. Running for a considerable time in an underinflated or overloaded condition is the single largest cause of tyre delamination. The most common example is seen on the side of the motorways in the UK where you can see the tread sections of both truck and car tyres on the hard shoulder.
This is usually due the tyre suffering a slow deflation and the losing pressure until the volume of air inside the tyre is insufficient to carry the loads and stresses placed upon it. As the tyre pressure drops the build up of heat within the casing leads to delamination and the component parts separate.

The consensus is that the tire is coming apart. Your next post
should report that the tire has been replaced.
Please can anyone confirm that i would need a new tire. I will take it off and do a wheel turn without rim/tire on tomorrow. And yes it does sound when i move even just a little bit. THank you all
