Narrative:
On wednesday I worked routine overnight shift. Aircraft came to the gate with the #1 main tire blown and flat. I changed the #1 main tire and brake assembly per the maintenance manual. I then completed the rest of the check and signed off all the required paperwork. Later that morning; my manager called me at home and told me that the #2 main tire should have been changed too due to the flat #1 main tire. He also told me the tire would be changed that afternoon.
