I have a slow lead in the side wall that came from scraping some kind
of sharp object laying by the curb. Looks like a 1/2-inch cut, but
jagged. Tire is tubeless radial. Is it possible to patch something
like this on the side wall? Patch kits say they are for the tread but
don't say specifically not to use them on the side.

2nd thought -- can I put a tube in it? Seems like I remember tire
places say tubeless can't be fixed with a tube, but I can't see why
not.

A tube should work, but any kind of cut could lead to a blow out.
Especially one on the side wall.
I say replace the tire.
