Narrative:
On mar/thu/04, I was in the process of performing a preflight inspection/walkaround on aircraft at gate. As I walked around the right main landing gear, I observed a deep cut, approximately 2.5 inches in length, that extended into the tire groove. According to limits, the tire needed changing. I looked at the tire's sidewall, which is what I have gotten in the habit of doing and noticed B767ER stenciled on the side. I went to get a tire. There was a B767ER tire there, so I brought it back. Another technician and myself installed the wheel assembly, rotated the tire and torqued the axle nut per manual. The aircraft left. The next morning we were informed of our mistake via e-mail. I feel this incident could have been avoided if it were not for the fact that we have many variations of B767's, different series. Some are international, some domestic, some domestics are used on international rtes, some intls are used on domestic rtes. If we could keep domestic aircraft and tires separate from international aircraft, this occurrence could be avoided.

Title: A B767-300 WAS DISPATCHED IN NON COMPLIANCE WITH AN EXTENDED RANGE ACFT HVY WHEEL AND TIRE INSTALLED ON A DOMESTIC AIRPLANE.
Narrative: ON MAR/THU/04, I WAS IN THE PROCESS OF PERFORMING A PREFLT INSPECTION/WALKAROUND ON ACFT AT GATE. AS I WALKED AROUND THE R MAIN LNDG GEAR, I OBSERVED A DEEP CUT, APPROX 2.5 INCHES IN LENGTH, THAT EXTENDED INTO THE TIRE GROOVE. ACCORDING TO LIMITS, THE TIRE NEEDED CHANGING. I LOOKED AT THE TIRE'S SIDEWALL, WHICH IS WHAT I HAVE GOTTEN IN THE HABIT OF DOING AND NOTICED B767ER STENCILED ON THE SIDE. I WENT TO GET A TIRE. THERE WAS A B767ER TIRE THERE, SO I BROUGHT IT BACK. ANOTHER TECHNICIAN AND MYSELF INSTALLED THE WHEEL ASSEMBLY, ROTATED THE TIRE AND TORQUED THE AXLE NUT PER MANUAL. THE ACFT LEFT. THE NEXT MORNING WE WERE INFORMED OF OUR MISTAKE VIA E-MAIL. I FEEL THIS INCIDENT COULD HAVE BEEN AVOIDED IF IT WERE NOT FOR THE FACT THAT WE HAVE MANY VARIATIONS OF B767'S, DIFFERENT SERIES. SOME ARE INTL, SOME DOMESTIC, SOME DOMESTICS ARE USED ON INTL RTES, SOME INTLS ARE USED ON DOMESTIC RTES. IF WE COULD KEEP DOMESTIC ACFT AND TIRES SEPARATE FROM INTL ACFT, THIS OCCURRENCE COULD BE AVOIDED.
