Narrative:
I was changing nose tires on a 700 aircraft on gate X. I installed the nose tires and finished the paperwork. I was informed on jul/xa/08. Quality control called and informed that aircraft had -300 nose tires on it. He let me know that I had put the wrong nose tires on and I did not realize it until then.
