Narrative:

During routine through-flight inspection of aircraft xyz I found the right outboard main landing gear tire approaching tread wear limits. I made a logbook entry on log page #zyzy to replace the tire/wheel assembly within 12 lndgs per air carrier standard practices manual. I removed the maintenance copy of the log page. I dispatched the aircraft. I returned to the maintenance office to enter this item in the aircraft maintenance computer. I found that I had mistakenly wrote the words 'left main landing gear.' I have no explanation for why I wrote 'left' when meant 'right.' I have been working on aircraft for 20 yrs. I know aircraft right from left. I called air carrier aircraft maintenance planning and told them about my error. I called the station where the aircraft would receive overnight maintenance check and told them about my logbook error. I corrected the copy of the log page that I had per air carrier maintenance policies procedures manual. The only information that I can add is that I was standing on the loading bridge (jetway) when I was making this entry in the logbook. This was about 8 mins before departure.
