Narrative:

I received information that an incident occurred on dec/xa/99 concerning the wrong tire being installed on aircraft xyz, #7 position. The aircraft was a dash 200 series, and the tire was a dash 300 (part #XXX) tire assembly. The incorrect tire was discovered before the flight the next day and was corrected immediately before flight. I was called in for 4 hours early overtime for the terminal. When I reported to the terminal, they told me to go back to the hangar. I rode the employee bus back and was then assigned to said aircraft at hangar. When I arrived, the check and the tire change had commenced. I went in to stores for gloves and came out to help vxv abc with changing the #7 tire. There may have been a third person, but since it was not uncommon for the 4 early guys to work the B767, I don't recall exactly. I signed the tire log and filled out the paperwork as normal when helping out. And also backed checked the safety and torque of tire. Callback conversation with reporter revealed the following information: the reporter stated the B767-300 tire has a slightly greater diameter and a larger heat shield. The reporter said the identify of the wheel and tire assembly is the real problem, as the tire is not stenciled with the aircraft type but marked on the wheel half inner flange and depending on wheel placement is not visible. The reporter said the WX was extremely bad with a cold driving rain and limited visibility.
