Narrative:
I was involved in replacing the left and right nose tires on aircraft. I may have inadvertently left the spacers out of the installation of the new tire/wheel assembly. I do not believe that the spacers were originally there. I followed maintenance manual card 32-96-10 which states that there should be a maximum of 2-3 threads showing. This thread count is maintained even with the spacer missing. There was no aircraft incident.
