Or maybe the rear? Until it stops raining and I can drive along side a wall the closest sound I can describe it to is someone walking inside with wet shoes. Maybe the first few rotations it wont make any sound but it happens no matter if you are hard on the brakes or not..

 

I also noticed it's not as loud when backing up.

I had a tire that made that kind of noise because a belt pulled loose inside the tire. It was a squishing kind of rubbery sound like walking in a wet sneaker on tile flooring.

 

Do you notice any vibration at speed or side wiggle while driving slowly when you hear it?

not at slow speed but at high speed yes anything above 60 MPH on or off throttle.

 

could be the belts since the tires are about end of life I did not think about that and I was driving to pick up a desk chair and I was passing a long wall at around 70 MPH and the sound of it gets a little drowned out at speed but it does not really seem to get all that faster which points to something that is of a large diameter like the tire.

 

But yeah the way you said it sounds like what I hear a squishing rubber type of sound.
