Increase tyre pressure, but it may be too late.
By the looks of it, their profile is prone to sawtooth building, which causes road noise that might easily be mistaken for a shot bearing.

(Looking at a tyre from the front, if there's lots of small, well spaced, unconnected rubber blocks with upward pointing triangles /\ , it's prone to sawtooth building. The points of these rubber blocks are the last piece of that block to shear off the ground as the tyre rolls, and the points will wear off faster than the leading edge of the next rubber block.
If it's gone bad, you can simply feel it.)

As for the tyres , do you want all-seasons, or switch between winter and summer tyres ?
And what size of tyres do you want ?
