Narrative:
After takeoff and gear up from cdg on runway 26R, cdg tower said that we might have blown a tire on takeoff. Takeoff seemed normal, but bumpy like a rough runway, not nearly as rough as blown tire in company flight simulator. Not anywhere close to that rough. Gear had raised normally. Brake temperatures and hydraulic were normal. We were later informed via ACARS that a tire and wheel (#3) were found by maintenance on the runway 26R at cdg. Although we have an emergency procedure for a blown tire with landing gear down, there is no procedure for discovering you have a blown tire after landing gear are up. Our gear had been up for an hour when a missing wheel was confirmed. Since we had no indication of high temperature or hydraulic leak, we elected to continue to ZZZ, us and a light fuel weight landing. We do not know what caused the problem in the wheel. It checked normal during walk around preflight inspection. Captain flew the emergency landing at ZZZ, us. Callback conversation with reporter revealed the following information: the reporter stated that the crew was aware of one tire and wheel assembly replaced in ZZZ, us. The reporter said the alert from cdg only mentioned one wheel assembly was found and reported but in fact two wheel assemblies were missing. The reporter said some right inboard flap damage was incurred in this incident.

Title: A DC10-30 FREIGHTER ON TKOF HAD TWO R MAIN LNDG GEAR WHEEL ASSEMBLIES DEPART THE ACFT.
Narrative: AFTER TKOF AND GEAR UP FROM CDG ON RWY 26R, CDG TWR SAID THAT WE MIGHT HAVE BLOWN A TIRE ON TKOF. TKOF SEEMED NORMAL, BUT BUMPY LIKE A ROUGH RWY, NOT NEARLY AS ROUGH AS BLOWN TIRE IN COMPANY FLT SIMULATOR. NOT ANYWHERE CLOSE TO THAT ROUGH. GEAR HAD RAISED NORMALLY. BRAKE TEMPS AND HYD WERE NORMAL. WE WERE LATER INFORMED VIA ACARS THAT A TIRE AND WHEEL (#3) WERE FOUND BY MAINT ON THE RWY 26R AT CDG. ALTHOUGH WE HAVE AN EMER PROC FOR A BLOWN TIRE WITH LNDG GEAR DOWN, THERE IS NO PROC FOR DISCOVERING YOU HAVE A BLOWN TIRE AFTER LNDG GEAR ARE UP. OUR GEAR HAD BEEN UP FOR AN HR WHEN A MISSING WHEEL WAS CONFIRMED. SINCE WE HAD NO INDICATION OF HIGH TEMP OR HYD LEAK, WE ELECTED TO CONTINUE TO ZZZ, US AND A LIGHT FUEL WT LNDG. WE DO NOT KNOW WHAT CAUSED THE PROB IN THE WHEEL. IT CHKED NORMAL DURING WALK AROUND PREFLT INSPECTION. CAPT FLEW THE EMER LNDG AT ZZZ, US. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT THE CREW WAS AWARE OF ONE TIRE AND WHEEL ASSEMBLY REPLACED IN ZZZ, US. THE RPTR SAID THE ALERT FROM CDG ONLY MENTIONED ONE WHEEL ASSEMBLY WAS FOUND AND RPTED BUT IN FACT TWO WHEEL ASSEMBLIES WERE MISSING. THE RPTR SAID SOME R INBOARD FLAP DAMAGE WAS INCURRED IN THIS INCIDENT.
