Recommissioning my bike - weird tyre noise

After a few years off I have been getting my bikes back on the road (or should that be mud)

One of them has a pair of new (about 10 years ago) folding bead Continental Traction Pro with orange and black tread rubber - probably a bit retro these days! They cost the best part of £100, have almost no use and look so cool - so I am loathed to bin them

The tyres lost all air in storage and the black sidewall rubber has creased (and peeled a little in places)

So I put 45psi in the them to see if they went pop. . . . no worries, so I went for a ride and gave them a hard time on rocks and roots - they seemed fine. The carcase looks fine but some sidewall rubber has come off

But - the rear one makes a strange "squelching" noise as it rotates

Any thoughts?

    Maybe the bead slipping slightly on the rim, or maybe some condensation somewhere? (thinking between tyre and tube so a 'lump' as the wheel rotates, if they deflate completely, it wouldn't be a surprise).

    Maybe a kitten crawled in there.

    rubber perishes with age - about 7 or 8 years.

    car/motorbike tyres have a shelf life of 5 years

    Thats very much storage dependant, space savers spare wheels for example experience no UV light and last a lot longer.
