(1) tire has a slow leak, your risk to take on and repair.
The tire shop mistakenly marked one of the rear tires bad, and crossed out.
The questionable tire is marked bad. Started off from a slow leak, lost 1-2 psi a day, to unable to maintain pressure. I suspect a pebble/rock went too far. Maybe repairable?? I don’t know.
I am selling as is (3) tires, buyer’s risk/responsibility for the (1) bad tire. Asking $600 OBO. I am located in the Los Angeles area, would prefer a local transaction.
