I was called to aircraft for a cut in the # 4 main tire. Since the aircraft was due to depart in approximately 30 minutes. I asked for assistance from Mechanic Y to change # 4 main tire. I finished the installation of the tire while I proceeded to sign-off the entry in the logbook. After returning back to the Shop; Mechanic Y explained to me that he might have left a tool on the right Main Gear Spray Deflector. I policed the area that we had been working in and was unable to locate the tool. The tool was found on the Ramp after filing out this report.
A Line Mechanic reports changing # 4 right main tire on a B717 aircraft with the assistance of Mechanic Y; who later told him; that he; Mechanic Y; may have left a tool on the right Main Gear Spray Deflector.
