Narrative:

I was informed tonight on sep/wed/05 at XA30 by my supervisor that I had installed the incorrect nose tires on aircraft back on aug/fri/05. He told me that on sep/mon/05 while another shift was doing a hot tire pressure check; they noted the improper nose tires; and installed the correct tires without delay or incident. On aug/fri/05; aircraft X was the 3RD of 4 aircraft that my partner and I were responsible for. I was the brake rider. Upon reaching the park; I performed the walkaround and found the nose tires with cord coming through. Once caught up with me; we were fairly busy at that time. I informed him that we needed nose tires. He returned with everything on his golf cart to change the tires. I went into changing the tires without a thought. This is a routine item -- I never asked or looked closely at the tugs.
