Narrative:

When replacing right nose tire/wheel assembly; on air carrier X aircraft in jul/xa/07; the anti-rotation ring was not installed. I checked the old tire/wheel assembly and did not notice the spacer was still in the old tire/wheel assembly; and installed the new tire/wheel assembly. The spacer was noticed missing at destination when the aircraft arrived. The missing anti-rotation ring did not cause any shimmy or damage to the aircraft. Checking the used tire in ZZZ the anti-rotation ring was discovered in the old wheel assembly. Was counseled by local management to slow down; and when in doubt read; consult the illustrated parts manual.
