Hi all, I was thinking of gluing on a pair of new (but older) Vittoria Pave tires that I haven't used for a few years. They've been inside wheel bags and indoors.

Wanted to ask for opinions on whether they looked safe to ride on; the tread is free of cracks, but some stitching is exposed on the sidewalls--I took a couple pictures of the worst spots.
They hold air fine and look OK to me, but I'm not completely sure. Do I toss them instead?

Any input would be appreciated, thanks!
