Narrative:
On sat/apr/03, I installed 2 nosewheel assemblies on aircraft. Both part tags had the correct part numbers for this aircraft. Later I was informed that both part tags showed the correct part number for this aircraft. The tires were incorrectly tagged. Both wheels are similar in size with the same appearance. Although I verified serial numbers, I did not adequately confirm the part number on this wheel to assure it matched its tag. The difference between A-1 and A-2 tire is a major thing.
