Narrative:

During the remove and replace (right/right) of a #2 main tire per (aircraft maintenance manual) amm 32-42-11 on an A319 aircraft; the maintenance manual called for new nuts to be placed on the main wheel nut as well as new cotter pins. Other cotter pins were used from personal stock as well as the original nuts for the main wheel nut were used. A calibrated torque wrench was used for the main wheel nut (300.14 ft pounds; 149.70 ft pounds). A torque wrench was not used requiring 39-in/lbs on the castellated nuts. A new discrepancy [write-up] was created to replace the nuts and cotter pins at the next available maintenance layover. However; it was also discovered from an [FAA] inspector that an axle thread protector was not utilized during the repair per the amm. The main issue with the inspector is that a thread protector was not used; a torque wrench not used for the castellated nuts (39.2 pounds inches). The re-using of the nuts can be found under chapter 20-21-11 of the A319/A320 amm. A new discrepancy had been made to replace the nuts at the next maintenance visit [not layover]. The environment during the aforementioned maintenance action was as follows:- did not realize the recent revision to the procedure of requiring new nuts- the flight crew was soon to run out of time for the day- we were under pressure to expedite the repair without compromising airworthiness and safety at no-time during the maintenance action was safety compromised for the aircraft departure intentional.
